Loss of the ability to recall information that had been previously encoded in memory prior to a specified or approximate point in time. This process may be organic or psychogenic in origin. Organic forms may be associated with CRANIOCEREBRAL TRAUMA; CEREBROVASCULAR ACCIDENTS; SEIZURES; DEMENTIA; and a wide variety of other conditions that impair cerebral function. (From Adams et al., Principles of Neurology, 6th ed, pp426-9)
Loss of the ability to form new memories beyond a certain point in time. This condition may be organic or psychogenic in origin. Organically induced anterograde amnesia may follow CRANIOCEREBRAL TRAUMA; SEIZURES; ANOXIA; and other conditions which adversely affect neural structures associated with memory formation (e.g., the HIPPOCAMPUS; FORNIX (BRAIN); MAMMILLARY BODIES; and ANTERIOR THALAMIC NUCLEI).

A syndrome characterized by a transient loss of the ability to form new memories. It primarily occurs in middle aged or elderly individuals, and episodes may last from minutes to hours. During the period of amnesia, immediate and recent memory abilities are impaired, but the level of consciousness and ability to perform other intellectual tasks are preserved. The condition is related to bilateral dysfunction of the medial portions of each TEMPORAL LOBE. Complete recovery normally occurs, and recurrences are unusual.

Recovery from anterograde and retrograde amnesia after percutaneous drainage of a cystic craniopharyngioma. (1/84)

A case is reported of a cystic craniopharyngioma involving the floor and walls of the third ventricle. Pronounced anterograde and retrograde amnesia were documented preoperatively by formal testing. Rapid improvement in both new learning capacity and remote memory occurred after percutaneous twist drill drainage of the cystic portion of the tumour. The relevance of these observations to the amnesic syndrome and its neuropathological basis is discussed.  (+info)

Naloxone in the prevention of the adverse cognitive effects of ECT: a within-subject, placebo controlled study. (2/84)

Electroconvulsive therapy (ECT) is a highly effective treatment for major depression, but is also associated with characteristic cognitive side effects. Several reports document that endogenous opioids and their receptors are activated by electroconvulsive shock (ECS) and that naloxone in doses sufficient to block endogenous opioid receptors may reverse ECS-induced retrograde amnesia. This placebo-controlled, randomized, within-patient study was conducted to examine the potential of naloxone, given in doses sufficient to block opioid receptors (high dose), to ameliorate acute anterograde and retrograde memory impairments following ECT. Compared to placebo and low dose naloxone, high dose naloxone administered immediately before ECT resulted in significant reductions in anterograde amnesia, and better performance on an attention task. Both low and high dose naloxone improved verbal fluency. There were no beneficial effects of high dose naloxone on retrograde amnesia, and an indication that high dose naloxone may have worsened retrograde amnesia for shape stimuli. There were no effects of high dose naloxone on seizure duration, vital signs, and subjective side effects. The study is consistent with prior research in which change in behavioral and physiological measures was produced principally by naloxone doses sufficient to block endogenous opioid receptors and offers evidence of the potential for ameliorating some adverse cognitive effects associated with ECT.  (+info)

Anterograde and retrograde amnesia after lesions to frontal cortex in rats. (3/84)

A socially acquired food-preference test was used to assess effects of lesions to the frontal cortex on anterograde and retrograde memory in rats. In Experiment 1, there was no effect of lesion when rats were administered a two-choice test in which the target food was to be selected in the presence of a single distractor. In Experiment 2, a three-choice memory test was administered in which the target food was presented along with two equally palatable alternatives. In the latter test, lesioned groups displayed anterograde amnesia that increased with the length of the interval between postoperative acquisition and test, and a severe retrograde amnesia that extended equally over the entire range of intervals between preoperative acquisition and test. This outcome, which contrasted with the pattern of memory loss previously observed in rats with hippocampal lesions on this test, was interpreted as evidence for the strategic role of the frontal lobes in directing response selection and retrieval processes in memory.  (+info)

Reactivation-dependent changes in memory states in the terrestrial slug Limax flavus. (4/84)

The change in memory state in the terrestrial slug Limax flavus was studied using cooling-induced retrograde amnesia. Slugs were first conditioned to avoid carrot odor and then a second conditioning procedure was applied 1, 3, 6, or 7 days after the first conditioning trial. Cooling the slugs to approximately 1 degrees C on day 7 immediately after the presentation of the odor used in the conditioning resulted in retrograde amnesia in the slugs that were subject to a second conditioning on day 6 or 7, but not in slugs that were subject to a second conditioning on day 1 or 3. Next, second-order conditioning was used as the second conditioning procedure to distinguish the memory acquired in the first conditioning from that acquired in the second conditioning and similar results were obtained. These results suggest that the reactivation of memory altered the memory state from a cooling-insensitive state to a cooling-sensitive one. A possible model for memory states is discussed.  (+info)

Computer-assisted behavioral assessment of Pavlovian fear conditioning in mice. (5/84)

In Pavlovian fear conditioning, a conditional stimulus (CS, usually a tone) is paired with an aversive unconditional stimulus (US, usually a foot shock) in a novel context. After even a single pairing, the animal comes to exhibit a long-lasting fear to the CS and the conditioning context, which can be measured as freezing, an adaptive defense reaction in mice. Both context and tone conditioning depend on the integrity of the amygdala, and context conditioning further depends on the hippocampus. The reliability and efficiency of the fear conditioning assay makes it an excellent candidate for the screening of learning and memory deficits in mutant mice. One obstacle is that freezing in mice has been accurately quantified only by human observers, using a tedious method that can be subject to bias. In the present study we generated a simple, high-speed, and highly accurate algorithm that scores freezing of four mice simultaneously using NIH Image on an ordinary Macintosh computer. The algorithm yielded a high correlation and excellent linear fit between computer and human scores across a broad range of conditions. This included the ability to score low pretraining baseline scores and accurately mimic the effects of two independent variables (shock intensity and test modality) on fear. Because we used a computer and digital video, we were able to acquire a secondary index of fear, activity suppression, as well as baseline activity scores. Moreover, we measured the unconditional response to shock. These additional measures can enhance the sensitivity of the assay to detect interesting memory phenotypes and control for possible confounds. Thus, this computer-assisted system for measuring behavior during fear conditioning allows for the standardized and carefully controlled assessment of multiple aspects of the fear conditioning experience.  (+info)

Profound amnesia after damage to the medial temporal lobe: A neuroanatomical and neuropsychological profile of patient E. P. (6/84)

E. P. became profoundly amnesic in 1992 after viral encephalitis, which damaged his medial temporal lobe bilaterally. Because of the rarity of such patients, we have performed a detailed neuroanatomical analysis of E. P.'s lesion using magnetic resonance imaging, and we have assessed his cognitive abilities with a wide range of neuropsychological tests. Finally, we have compared and contrasted the findings for E. P. with the noted amnesic patient H.M, whose surgical lesion is strikingly similar to E. P.'s lesion.  (+info)

Phosphorylated cAMP response element-binding protein as a molecular marker of memory processing in rat hippocampus: effect of novelty. (7/84)

From mollusks to mammals the activation of cAMP response element-binding protein (CREB) appears to be an important step in the formation of long-term memory (LTM). Here we show that a 5 min exposure to a novel environment (open field) 1 hr after acquisition of a one-trial inhibitory avoidance training hinders both the formation of LTM for the avoidance task and the increase in the phosphorylation state of hippocampal Ser 133 CREB [phosphorylated CREB (pCREB)] associated with the avoidance training. To determine whether this LTM deficit is attributable to the reduced pCREB level, rats were bilaterally cannulated to deliver Sp-adenosine 3', 5'-cyclic monophosphothioate (Sp-cAMPS), an activator of PKA. Infusion of Sp-Adenosine 3',5'-cyclic monophosphothioate Sp-cAMPS to CA1 region increased hippocampal pCREB levels and restored normal LTM of avoidance learning in rats exposed to novelty. Moreover, a 5 min exposure to the open field 10 min before the avoidance training interferes with the amnesic effect of a second 5 min exposure to the open field 1 hr after avoidance training and restores the hippocampal levels of pCREB. In contrast, the avoidance training-associated activation of extracellular signal-regulated kinases (p42 and p44 mitogen-activated protein kinases) in the hippocampus is not altered by novelty. Together, these findings suggest that novelty regulates LTM formation by modulating the phosphorylation state of CREB in the hippocampus.  (+info)

Retrograde amnesia for spatial memory induced by NMDA receptor-mediated long-term potentiation. (8/84)

If information is stored as distributed patterns of synaptic weights in the hippocampal formation, retention should be vulnerable to electrically induced long-term potentiation (LTP) of hippocampal synapses after learning. This prediction was tested by training animals in a spatial water maze task and then delivering bursts of high-frequency (HF) or control stimulation to the perforant path in the angular bundle. High-frequency stimulation induced LTP in the dentate gyrus and probably also at other hippocampal termination sites. Retention in a later probe test was disrupted. When the competitive NMDA receptor antagonist 3-(2-carboxypiperazin-4-yl)propyl-1-phosphonic acid (CPP) was administered before the high-frequency stimulation, water maze retention was unimpaired. CPP administration blocked the induction of LTP. Thus, high-frequency stimulation of hippocampal afferents disrupts memory retention only when it induces a change in the spatial pattern of synaptic weights. The NMDA receptor dependency of this retrograde amnesia is consistent with the synaptic plasticity and memory hypothesis.  (+info)

Limbic encephalitis with antibodies to the voltage-gated potassium channel-complex (VGKC-LE) is now a well-established neurological syndrome. Recent work demonstrates many patients suffer from persisting anterograde amnesia following the resolution of VGKC-LE. However, no detailed assessment of retrograde memory, episodic or otherwise, has yet been undertaken. We assessed 14 VGKC-LE patients and 14 age-matched controls were assessed on a detailed measure of retrograde episodic memory (the Autobiographical Interview). One episodic memory was obtained from each decade of life (six in total). The results show that VGKC-LE patients had significant deficits in episodic recall across the most recent 40 years of their life, in the context of preserved personal semantic memory (as measured by the Autobiographical Memory Interview). Moreover, ultra-high field magnetic resonance imaging suggests that VGKC-LE is associated with focal hippocampal atrophy. These data demonstrate that retrograde amnesia is ...
A 54 year old patient of average intelligence with a severe and enduring loss of old autobiographical memories after herpes simplex type 1 infection is described. She was tested with a comprehensive neuropsychological battery two years after the infection. Special emphasis was laid on examining different aspects of retrograde memory. The neurological examination involved MRI and SPECT. Brain damage was found mainly in the right temporofrontal region, but minor left sided damage to this region seems possible. The patient was in the normal or slightly subnormal range for all tested anterograde memory functions, but manifested severe retrograde memory deficits with respect to episodic old memories and more moderate deficits in tests of general knowledge (semantic old memories). It is concluded that the ecphory of old autobiographical memories relies heavily on an activation of the right lateral temporofrontal junction area, but that probably only some complementary left hemispheric damage to these ...
People with retrograde amnesia have trouble accessing memories from before the onset of amnesia. Well tell you what you need to know.
There are many controversies concerning the structural basis of retrograde amnesia (RA). One view is that memories are held briefly within a medial temporal store (hippocampal complex) before being consolidated or reorganised within temporal neocortex and/or networks more widely distributed within the cerebral cortex. An alternative view is that the medial temporal lobes are always involved in the storage and retrieval (reactivation) of autobiographical memories (multiple trace theory). The present study used quantitative magnetic resonance imaging (MRI) in 40 patients with focal pathology/volume loss in different sites, to examine the correlates of impairment on three different measures of RA. The findings supported the view that widespread neural networks are involved in the storage and retrieval of autobiographical and other remote memories. Brain volume measures in critical structures could account for 60% of variance on autobiographical memory measures (for incidents and facts) in diencephalic
We report the case of a 42-year-old man (patient CL) who developed a particular profile of amnesia with two dates of onset. At the first onset, the patient suffered a mild/lmoderate injury that accounts for an initial anterograde and mild retrograde memory impairment. At the second onset, 8 months l …
Gade, A., & Mortensen, E.L. (1990). Temporal gradient in the remote memory impairment of amnesic patients with lesions in the basal forebrain. Neuropsychologia, 28, 985-1001. Recall and recognition of premorbid public events were studied in four groups of subjects. Dementia patients showed equal losses from all time periods compared to normal controls. In contrast, two groups of amnesic patients showed extensive remote memory losses, which were most marked for the last few years prior to onset. The difference between recall and recognition was similar in the groups. The results indicate that the retrograde amnesia associated with aneurysms of the anterior communicating artery cannot be distinguished from that of amnesia with other etiologies. Implications of the finding of a temporal gradient in the retrograde amnesia of non-alcoholic amnesics are discussed. ...
The hippocampus is critical to the formation of memories and the retention of them. Damage to the hippocampus can cause both retrograde amnesia (loss of previous memories) and anterograde amnesia (ability to form new memories).. Memory loss is one of the earliest symptoms of Alzheimers disease, and the hippocampus is one of the first areas of the brain to deteriorate.. ...
Injury or trauma to head is the most leading cause of memory disorders. Injury to brain leads to tissue displacement, disruption of vascular channels, subsequent hemorrhage and edema. This damage impairs memory functions and causes a person to loss memory either transient or permanent. Person is unable to recall about what happened with him. If lesion is in hippocampus, some degree of retrograde amnesia occurs in which person fails to recall memories from the past and its lesion can also lead to anterograde amnesia in which people unable to establish new long term memories of those types of information that are the basis of intelligence.. Diseases like Alzheimer leads to memory loss and mostly this disease occur in late age. This is the degenerative disease results in formation of plaques in brain areas and the cortex becomes atrophic. This disease is characterized by dementia in which intellectual functions of brain are disturbed. It widely effects to thinking, talking, judgment and memory. ...

These case studies … ...
If its any consolation, retrograde amnesia tends to affect episodic memory (which is personal in some way, inherently subjective) more than semantic memory (which is like facts about the world, inherently objective). Its plausible that hed forget his past but remember the existence of a film. ...
In humans, the ability to form new declarative memories and recall those created in the recent past depends on the integrity of the hippocampus (Squire, 1992). Context fear memories in rodents show a similar dependence on this structure (Kim and Fanselow, 1992). Lesions of the rodent hippocampus produce robust retrograde amnesia for context fear. As in humans, the amnesia is temporally graded and does not extend to context memories formed in the remote past (Anagnostaras et al., 1999). However, in contrast to the human literature, the ability to form new context fear memories is sometimes spared in lesioned animals (Maren et al., 1997; Cho et al., 1999). The current set of experiments addressed this discrepancy by demonstrating that context fear memories formed during a single learning trial always require the hippocampus. The use of multiple learning trials can overcome this deficit. These results are consistent with studies of spatial memory that show single-trial learning is particularly ...
Memories that have been lost as a result of amnesia can be recalled by activating brain cells with light. In a paper published today in the journal , researchers at MIT reveal that they were able to reactivate memories that could not otherwise be retrieved, using a technology known as optogenetics.. The finding answers a fiercely debated question in neuroscience as to the nature of amnesia, according to Susumu Tonegawa, the Picower Professor in MITs Department of Biology and director of the RIKEN-MIT Center at the Picower Institute for Learning and Memory, who directed the research by lead authors Tomas Ryan, Dheeraj Roy, and Michelle Pignatelli.. Neuroscience researchers have for many years debated whether retrograde amnesia -- which follows traumatic injury, stress, or diseases such as Alzheimers -- is caused by damage to specific brain cells, meaning a memory cannot be stored, or if access to that memory is somehow blocked, preventing its recall.. The majority of researchers have favored ...
On July 3, 2003, while riding the New York subway, 35-year-old former stockbroker and photography student Doug Bruce suddenly experienced a rare form of retrograde amnesia. Though his entire episodic (autobiographical) memory was wiped clean, his procedural (skill-based) memory remained intact. Over the course of a year, Bruce videotaped himself as he pieced together the facts of his forgotten life while trying to forge a new identity for himself. British TV documentarian Rupert Murray, whod known Bruce for nearly two decades, decided to document the experience. Though Doug no longer recognized him as a friend, Murray still managed to secure his full cooperation. As outlandish as Doug Bruces situation may be, ultimately, whats remarkable about Unknown White Male is how unaffecting this bizarre and potentially intriguing story turns out to be.

This brings me back to an old memory. Circa 1975 I was working with Rad Smith who was my first Uechi instructor. I think I must have asked an annoying question in class about the effectiveness of a technique, and so Rad was in a mood to break bad with me in partner exercises. For those who dont know the late Rad Smith... He was a sprinter and swimmer at Harvard, and he looked like it. After he got held up at knife point on a Boston subway over a leather jacket, Rad got his shodan from George with just one extremely intense year of training - and with Tomoyose Ryukos blessing. Bob Campbell spoke of working with him, and said Rad was one of the strongest people he ever faced. (Rad would tell me though that Bobby always knew what he was going to do before he did it.) In any case... in a partner exercise during that class, Rad hit me in the sternum with a vertical fist punch so hard that it felt like all the air went out of me. It took about 5 years before I no longer felt that spot when weight ...
Chapter One. She was fifteen years old and alone. The first gulp of the dark liquid scorched her throat and burned all the way down. Her eyes stung and she fought the urge to vomit.

When her vision cleared she saw her husband, Thomas, slumped in a straight-backed chair, his dark head cradled in his hands. What happened? she whispered.. Thomas jerked up when he heard her voice. Shadowy circles surrounded his deep brown ...

Post-traumatic amnesia (PTA) is a state of confusion that occurs immediately following a traumatic brain injury in which the injured person is disoriented and unable to remember events that occur after the injury. The person may be unable to state his or her name, where he or she is, and what time it is. When continuous memory returns, PTA is considered to have resolved. While PTA lasts, new events cannot be stored in the memory. About a third of patients with mild head injury are reported to have islands of memory, in which the patient can recall only some events. During PTA, the patients consciousness is clouded. Because PTA involves confusion in addition to the memory loss typical of amnesia, the term post-traumatic confusional state has been proposed as an alternative. There are two types of amnesia: retrograde amnesia (loss of memories that were formed shortly before the injury) and anterograde amnesia (problems with creating new memories after the injury has taken place). Both ...
Memory disturbances frequently occur after brain damage, but can be associated with psychiatric illnesses as well. Amnesia-the most severe form of memory impairment-has several variants, including anterograde and retrograde amnesia, material-specific and modality-specific amnesia, and transient global amnesia. We searched databases to obtain an overview of amnesia research from the past 5 years. Research into amnesia has increased exponentially, probably because of the availability of modern brain-imaging techniques. In line with the view that memory is not a unity but is organised into several systems, amnesia is described as a multifaceted disease with a frequently poor prognosis ...

N2 - The effects of non-competitive N-methyl-d-aspartate receptor antagonists on amnesia induced by carbon monoxide (CO) were investigated, since they have neuroprotective effects on delayed degeneration induced by ischemia. In the mice exposed to CO, acute and delayed amnesia were induced. (+)-MK-801 and (-)-MK-801 improved the delayed amnesia, but the effects of phencyclidine (PCP) were weak. (+)-MK-801 and PCP potentiated the acute amnesia. From these results, it is suggested that there is a stereoselectivity in the effects of MK-801 on CO-induced amnesia and that CO-induced delayed amnesia animals could be used as an ischemic amnesia model..

RIVISTA SPERIMENTALE DI FRENIATRIA - Amnesia dissociativa e trauma: una prospettiva secondo la teoria della dissociazione strutturale ( Nel DSM-IV lamnesia dissociativa è considerata unentità clinica distinta che può prendere le seguenti forme: amnesia localizzata, amnesia continua, amnesia sistematizzata, amnesia generalizzata e amnesia selettiva. In ambito clinico, tuttavia, essa è più comunemente presente come espressione sintomatica di disturbi più complessi ed estesi, soprattutto i disturbi dissociativi complessi (e spesso in pazienti che hanno subito traumi acuti e cronici). La dissociazione è il risultato di unintegrazione difettosa, che di solito si produce in occasione di esperienze traumatiche, di quei sistemi neuro-bio-psicologici dalla struttura estremamente complessa costituita dalla personalità. Questo difetto comporta una dissociazione della personalità in due o più parti scisse - sottosistemi dinamici e attivi, ma rigidi e relativamente chiusi. In base a questo approccio
This article examines the trope of amnesia—the crisis of memory—in two recent Chinese-language films dealing with traumatic memories of the Cultural Revolution and its aftermath: Zhang Yimou’s Coming Home (Guilai, 2014) and Wang Xiaoshuai’s Red Amnesia (Chuangru zhe, 2014). Cinematic representation of real and symbolic amnesia, I argue, can be an affective way to overcome historical amnesia, both institutionalized by the Party-state and privatized by individuals. By exploring the dynamics between forgetting and remembering at both collective and individual levels, we can reach a deeper understanding of the profound impact of the Cultural Revolution and its present-day repercussions.
There are no laboratory tests that are necessary to confirm amnesia nor are there any physical conditions that must be met. However, it is very important not to overlook a physical illness that might mimic or contribute to amnesia. If there is any doubt about a medical problem, the mental health professional should refer to a physician, who will perform a complete physical examination and request any necessary laboratory tests.. Very sophisticated psychological testing, called neuropsychological testing, can be very helpful in determining the presence of amnesia. Sometimes the diagnosis of amnesia can be aided by the use of brain scans such as the magnetic resonance imaging (MRI).. via.

It is true that stimulation of various parts of the brain can evoke memories, or at least memory-like experiences. The hippocampus, however, is not known as a hotspot for this. Early studies found that hippocampal stimulation produces amnesia, not memory recall, and heres a recent paper reporting that patients couldnt even tell whether their hippocampal stimulator was switched on or off, and reported no subjective memory effects.. Its especially unlikely that hippocampal stimulation would evoke 60 year old memories, because damage to the hippocampus is known to impair recall of recent events, and memory formation, while old memories (older than about 20 years pre-lesion) are spared, suggesting that theyre stored somewhere else in the brain.. Now, maybe Carson just mis-spoke and he meant to say the temporal cortex near the hippocampus. However, while stimulation of this region can indeed produce vivid memory experiences, theres no evidence that these memories are any more detailed or ...
The old theory is that once a memory is wired in your brain, it stays that way, explained Nader, William Dawson Scholar and EWR Steacie Fellow in the Department of Psychology. But our discovery shows that once you remember something, it doesnt stay wired in your brain, it becomes unwired and needs to be restored again - reconsolidation.. This latest finding builds on Naders previous research which showed that it was possible to chemically erase fearful memories in rats. That research shed light on the neurobiology of memory and showed that long-term memories can be unlocked and even modified. Naders discoveries challenged traditional views about the neural basis for memory.. The new findings deepen our understanding of the molecular basis by which the brain controls which memories do and do not undergo reconsolidation. Reconsolidation blockade has been suggested as a possible new treatment for sufferers of psychological disorders, including those involving uncontrollable, intrusive ...
Just casting about here, but wouldnt Propofol or a similar agent (if there is such a thing) additionally have an effect that from Joe and Dylans point of view would be advantageous; ie: amnesia. Though you use the word amnesia in the title of this post Im not seeing (or being obtuse and not seeing) the suggestion that Joe and or Dylan maybe initially banked on the amnesiatic (I am not sure if that is the correct form of that word, but causing memory loss is what I am talking about) properties of any of these drugs.. I think that in their delusion and malevolence these two men sought to incapacitate and sexually assault Robert and that they initially believed that the incapacitating drug would also produce amnesia in Robert. To the mentally disturbed and disinhibited by drug abuse and alcohol abuse this might seem like a good plan.. I remind all on this site that sexual crimes of this nature against women and girls are so commonplace that they arent even mentioned in the mainstream press ...
Treatment of amnesia depends on the root cause of amnesia and is handled on an individual basis. Psychotherapy can be helpful for amnesia caused by emotional trauma.
Amnesia is the inability to recall information which is stored in memory, meaning that it is the loss of memory, wih causes which may be organic or functional. Organic amnesia causes may include the damage to the brain through injury, or the use of certain drugs - usually sedative drugs. This is the forum for discussing anything related to this health condition
Infantile/childhood amnesia refers to a persons inability to recall events from early childhood. Infantile amnesia could be linked to language development.

The kind of long-term depression that we are talking about here is not the depressed psychological state that immediately comes to mind when you hear this expression. Rather, we are talking about a molecular process by which the brains neurons can reduce the efficiency of the connections between them. Long-term depression is, in a sense, the opposite of long-term potentiation, the process by which synaptic connections are strengthened in order to store new information in memory. Because the neurons of the brains two hippocampi, through which newly memorized facts enter, cannot keep strengthening their synapses indefinitely. Scientists believe that one possible role of long-term depression might be to bring the strengthened synapses back to their baseline level- resetting them to zero, so to speak, and thus erasing old memories so that new ones can be stored in their place.. If these memory traces have had enough time to be transferred from the hippocampus to other circuits of the brain, they ...
Basu Chatterjees remake of a Hollywood classic (12 Angry Men) is about a jury discussing the verdict of a young boy, accused of murder. Every one is convinced of the boys guilt - except one member. And he starts asking uncomfortable questions. A truly gripping film, set in one room for the entire duration, narrowly beats out Eternal Sunshine of the Spotless Mind, a film about blotting out unwanted memories. But after you have decided to do so, what if you change your mind? And after you have blotted out the old memories, what stops you from acquiring the same memories all over again ...
Ever since the night when he had evoked, for no apparent reason, a whole train of melancholy memories, pictures of his past life returned to Des Esseintes and gave him no peace.. He found himself unable to understand a single word of the books he read. He could not even receive impressions through his eyes. It seemed to him that his mind, saturated with literature and art, refused to absorb any more.. He lived within himself, nourished by his own substance, like some torpid creature which hibernates in caves. Solitude had reacted upon his brain like a narcotic. After having strained and enervated it, his mind had fallen victim to a sluggishness which annihilated his plans, broke his will power and invoked a cortege of vague reveries to which he passively submitted.. The confused medley of meditations on art and literature in which he had indulged since his isolation, as a dam to bar the current of old memories, had been rudely swept away, and the onrushing, irresistible wave crashed into the ...
Well, the guy with the camera approached us as we walked back across that famous old Ryman Auditorium stage. He told us that they were filming a documentary about Glens life. He asked Robert to say his name and contact info so he could get permission from us if they use it in the finished project. And before I knew it, I asked if I could tell him about my Glen Campbell back story, and he said of course. So I did, starting with my 3-year old memory, and my voice broke and I kept talking nearing the verge of tears. And he looked at me from behind his camera, and said, Wow. How did tonights experience match up to your memory of 1969? And I told him exactly what I felt: it was simply the same JOY I felt then. The exact same, only it had come full circle ...
Comment #56 September 9th, 2006 at 5:52 am Scott, I think Im just babbling about knots - Im drawing from old memories of pop science articles, which has possible failures at both the memory link and the what was written in the articles link.. Anyhow, what I know for a fact is that the problem of knot classification is still open, and that its intimately linked with the problem of 3-manifold classification, because the inverse space of a knot forms a 3-manifold, and at some point around 1990 or so it was shown that if two knots have the same manifold then theyre the same knot (but that isnt true of links).. The possible link to perelmans work is that articles I read on knots said that the big problem with classification was proving the poincare conjecture. Of course, its entirely possible that this was speculative wishful thinking, that it sure seemed like a first step in the direction of classification was to be able to prove poincare, but there wasnt a formal argument about why that ...
I dont like TV commercials or those dreaded infomercials any more than anyone else. Maybe I dislike them even more than most. But there is one type of infomercial that catches me & sets me down quietly in my chair to listen. Even if its a whole half hour long. I never have or likely ever will buy the product but my like for the product carries me through all the customary sales pitches. Its always a pleasant type of infomercial filled with many, many, old memories. Its those Time/Warner type music Infomercials where they play snippets of songs from the 50s, 60s, 70s etc. Could be the golden age of Country Music, could be the Doo Wop era or the Motown sound. Maybe the heavy age of Rock or romantic ballads of the 50s. Big Band. Doesnt really matter because it is all memory music for me. Each song brings back a different set of nostalgic feelings. People, places, events, good times, not so good times. It s all there in each snippet of music that is played. Not the whole song, just ...
The protective response causes APP (Amyloid Precursor Protein, the long molecule that protrudes from neurons) to be cut into four fragments, including amyloid-beta, that downsize the neural network and eventually destroy synapses and neurons. When the APP molecule is cut into those four pieces, it is not cut into the two pieces that nourish and maintain synapses. Alzheimers disease is a state of the brain in which there is an imbalance between the reorganization of synapses that have outlived their usefulness (and which the brain can stand to lose - healthy destruction) and the maintenance or creation of existing and new synapses (which the brain needs to sustain old memories and form new ones, as well as perform other cognitive functions). That imbalance comes from too many of the synapse- and neuron-destroying quartet of molecules snipped from APP and too few of the synapse- and neuron-sustaining duo of molecules snipped from APP ...
I got an important lesson in remembering how important that the things that arent there can be, and how hard it is to see that theyre not there, and in how inportant the things that we immediately worget can be, and how hard it can be to recall what youve forgotten. The wife and I go swimming at a municipal indoor pool thats not far but a few miles up the road. About halfway there the wife slams on the brakes for no reason apparent to me and then I saw the black fellow dressed in black jaywalking, well jayrunning Its a 40 MPH 4 lane road, lots of traffic. The car in the right lane didnt seem like he saw the fellow until the last second and I thought I was going to get to see a pedestrian popped into the air by a car again. It really was ,, that close. They actually go straight up when they get clobbered by a car at speed, at least the fellow I saw get it did. Thats a decades old memory that I could stand forgetting. Then the wife says why is it the ones that jaywalk are always dressed in ...
I have a unique life. And dont get me wrong, I love unique. I love that God made us all so different that on this planet of billions, not one person is alike. I even love diversity, coming from a small town it was my favorite thing about college. Ive always felt quite different, but I SO love that about myself now. But there are days. There are days that I would love to just be. Not to be the mom, the wife, the school psychologist; just be. Not to have people look at me with sad eyes and say, Hows Kennedy? Or a day when people dont say, You have 4 kids? I dont know how you do it.[insert pity face here] Sheesh! Dont get me wrong, I love all five of my lovelies. They brighten my life and I wouldnt want a life without any one of them in it. But just a break from the norm every now and then can be awesome. I recently got a glimpse of a day like that. I got to celebrate a grad school friends birthday with her and some friends. We laughed, shared old memories, and celebrated new ones. It ...
If there is any darkness in your cells, it may very well be released in your physical body, which could result in some body pain in one or more areas. If this applies to you, speak with your pain and ask what you can do to let it go. It could be resistance; it could be old memories or old wounds; it could be that your body is asking for Forgiveness of self and/or others. Follow the guidance of your body. Surrender to and follow what is shared, rather than wondering what it means. We are surrendering much of the old, so let the sacred waters of Soul help you let it go. Some other physical experiences you may have are disruptive sleep, headaches, feeling as though you arent even in your body; feeling disoriented, not remembering things that happened even a few minutes ago, things disappearing in different dimensions only to reappear in the same place or someplace different, nausea, rashes (especially where your chakras are) and more ...

Next is Series 2 Industrial. This subject matter is important, because any of us live in urban environments, take trains, travel in cars, planes, motorbikes etc. It is important to include the myriad of sounds and noises that are derived from these diverse types of transportation. The key is not hide from these sounds, they can be scary or feel harmful to those of us with tinnitus and so have to be reframed, to gently reintroduce them.. Toned down and carefully EQd recordings of planes, trains, boats and automobiles and associated sounds, most certainly have their own charm and can carry the most positive of connotations. If the connection is re-wired and re-worked it is then very possible to take those sounds and give them back to the user in a more palatable and less threatening manner.. Many tracks were designed to invoke old memories of safety and wonderment, using the sounds of steam trains, like a day trip with grandparents, a Citroen 2CV turning in a gravel drive in the South of ...

Needless to say, Meyer has nothing to say about this book. One wonders whether or not she ever took the time to read it. She thus establishes herself as a perfect example of why I continue to find the phrase cultural amnesia so relevant and significant. Do I really want to see large quantities of money managed by someone who cannot put the lessons of history into proper perspective before coming to conclusions? Of course the whole idea behind Viewpoint is that everyone is entitled to an opinion. My own opinion is that anyone hooked on this-time-its-different thinking is inviting the next economic crisis to set in before we have extricated ourselves from the current one. ...
