Anterograde and retrograde amnesia after lesions to frontal cortex in rats. (1/47)

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)

Brain correlates of memory dysfunction in alcoholic Korsakoff's syndrome. (2/47)

OBJECTIVES: To investigate the relation between anterograde amnesia and atrophy of brain structures involved in memory processing in alcoholic Korsakoff's syndrome. METHODS: The volume of brain structures involved in memory processing was measured with MRI from 13 subjects with Korsakoff's syndrome, 13 subjects with chronic alcoholism without Korsakoff's syndrome, and 13 control subjects. The brain structures analysed were the hippocampus, the parahippocampal gyrus, the mamillary bodies, the third ventricle, and the thalamus. Brain volumes were correlated with the delayed recall of a verbal learning test. RESULTS: Compared with subjects with chronic alcoholism and control subjects, subjects with Korsakoff's syndrome had a reduced volume of the hippocampus, the mamillary bodies, and the thalamus, and enlargement of the third ventricle. The impairment of delayed recall correlated with the volume of the third ventricle (r=-0.55, p=0.05) in the Korsakoff group. CONCLUSIONS: Anterograde amnesia in alcoholic Korsakoff's syndrome is associated with atrophy of the nuclei in the midline of the thalamus, but not with atrophy of the mamillary bodies, the hippocampus, or the parahippocampal gyrus.  (+info)

Pharmacokinetic-pharmacodynamic analysis of mnesic effects of lorazepam in healthy volunteers. (3/47)

AIMS: To describe the pharmacokinetic-pharmacodynamic modelling of the psychomotor and mnesic effects of a single 2 mg oral dose of lorazepam in healthy volunteers. METHODS: This was a randomized double-blind, placebo-controlled two-way cross-over study. The effect of lorazepam was examined with the following tasks: choice reaction time, immediate and delayed cued recall of paired words and immediate and delayed free recall and recognition of pictures. RESULTS: The mean calculated EC50 values derived from the PK/PD modelling of the different tests ranged from 12.2 to 15.3 ng ml-1. On the basis of the statistical comparison of the EC50 values, the delayed recall trials seemed to be more impaired than the immediate recall trials; similar observations were made concerning the recognition vs recall tasks. CONCLUSIONS: The parameter values derived from PK/PD modelling, and especially the EC50 values, may provide sensitive indices that can be used, rather than the raw data derived from pharmacodynamic measurements, to compare CNS effects of benzodiazepines.  (+info)

Amnesia due to fornix infarction. (4/47)

Background and Purpose-The fornix connects various structures involved in memory. We report a patient with anterograde amnesia after an acute ischemic infarct in the anterior fornix. Case Description-A 71-year-old female with acute-onset amnesia had neuroimaging studies showing ischemic infarction of both columns and the body of the fornix and the genu of the corpus callosum. Neuropsychological evaluation revealed anterograde amnesia without evidence of callosal disconnection. The patient showed marked improvement in her memory function on the follow-up visit. Conclusions-Amnesia in this case is likely due to infarction of the anterior fornix structures.  (+info)

Bilateral astrocytoma involving the limbic system precipitating disabling amnesia and seizures. (5/47)

Astrocytomas involving the limbic system are usually unilateral in nature. We report a very unusual case where a low-grade astrocytoma originating in the left temporal lobe spread to the right hippocampus through the hippocampal commissure to cause disabling amnesia and seizures. Some improvement in the memory deficit was facilitated by identification of complex partial status epilepticus. EEG should be performed in all patients with lesions of the limbic system and neuropsychological problems if ongoing seizure activity is not to be missed.  (+info)

Focal autobiographical amnesia in association with transient epileptic amnesia. (6/47)

Although problems with remembering significant events from the past (e.g. holidays, weddings, etc.) have been reported previously in patients with transient epileptic amnesia (TEA), to date there have been no detailed studies of autobiographical memory in patients with this disorder. To investigate this issue, a 68-year-old right-handed man (R.G.) who suffered from TEA and reported significant autobiographical memory problems was tested on a battery of neuropsychological tests of anterograde and remote memory. Tests of autobiographical memory revealed that R.G. was unable to evoke detailed autobiographical recollections from a substantial part of his life. By contrast, he performed well on tests of new learning and general knowledge and possessed good personal semantic information about his past. In summary, a distinct form of autobiographical amnesia, which is characterized by loss of experiential remembering of significant events, may be associated with TEA. It is proposed that the autobiographical memory deficit seen in the disorder may result from the progressive erasure of cortically based memory representations. This case adds to growing evidence for a dissociation between mechanisms subserving anterograde memory and those required to evoke remote episodic memories.  (+info)

Cognitive impairment after small-dose ketamine isomers in comparison to equianalgesic racemic ketamine in human volunteers. (7/47)

BACKGROUND: Ketamine is increasingly used in pain therapy but may impair brain functions. Mood and cognitive capacities were compared after equianalgesic small-dose S(+)-, R(-)-, and racemic ketamine in healthy volunteers. METHODS: Twenty-four subjects received intravenous 0.5 mg/kg racemic, 0.25 mg/kg S(+)-, and 1.0 mg/kg R(-)-ketamine in a prospective, randomized, double-blind, crossover study. Hemodynamic variables, mood, and cognitive capacities were assessed for 60 min. RESULTS: Transient increases in blood pressure, heart rate, and catecholamines were similar after administration of all drugs. At 20 min after injection, subjects felt less decline in concentration and were more brave after S(+)- than racemic ketamine. They reported being less lethargic but more out-of-control after R(-)- than racemic ketamine. Ketamine isomers induced less drowsiness, less lethargy, and less impairment in clustered subjective cognitive capacity than racemic ketamine for the 60-min study. Objective concentration capacity [test time, S(+): 25.4 +/- 15.2 s, R(-): 34.8 +/- 18.4 s, racemic ketamine: 40.8 +/- 20.8 s, mean +/- SD] and retention in primary memory [test time, S(+): 4.6 +/- 1.2 s, R(-): 4.2 +/- 1.4 s, racemic ketamine: 4.0 +/- 1.4 s, mean +/- SD] declined less after S(+)- than either R(-)- or racemic ketamine at 1 min. At 5 min, immediate recall, anterograde amnesia, retention in primary memory, short-term storage capacity, and intelligence quotient were less reduced after the isomers than racemic ketamine. Speed reading and central information flow decreased less after S(+)- than racemic ketamine. CONCLUSIONS: Early after injection, ketamine isomers induce less tiredness and cognitive impairment than equianalgesic small-dose racemic ketamine. In addition, S(+)-ketamine causes less decline in concentration capacity and primary memory. The differences in drug effects cannot be explained by stereoselective action on one given receptor.  (+info)

Isoflurane causes anterograde but not retrograde amnesia for pavlovian fear conditioning. (8/47)

BACKGROUND: Production of retrograde amnesia by anesthetics would indicate that these drugs can disrupt mechanisms that stabilize memory. Such disruption would allow suppression of memory of previous untoward events. The authors examined whether isoflurane provides retrograde amnesia for classic (Pavlovian) fear conditioning. METHODS: Rats were trained to fear tone by applying three (three-trial) or one (one-trial) tone-shock pairs while breathing various constant concentrations of isoflurane. Immediately after training, isoflurane administration was either discontinued, maintained unchanged, or rapidly increased to 1.0 minimum alveolar concentration for 1 h longer. Groups of rats were similarly trained to fear context while breathing isoflurane by applying shocks (without tones) in a distinctive environment. The next day, memory for the conditioned stimuli was determined by presenting the tone or context (without shock) and measuring the proportion of time each rat froze (appeared immobile). For each conditioning procedure, the effects of the three posttraining isoflurane treatments were compared. RESULTS: Rapid increases in posttraining isoflurane administration did not suppress conditioned fear for any of the training procedures. In contrast, isoflurane administration during conditioning dose-dependently suppressed conditioning (P < 0.05). Training to tone was more resistant to the effects of isoflurane than training to context (P < 0.05), and the three-trial learning procedure was more was more resistant than the one-trial procedure (P < 0.05). CONCLUSIONS: Isoflurane provided intense dose-dependent anterograde but not retrograde amnesia for classic fear conditioning. Isoflurane appears to disrupt memory processes that occur at or within a few minutes of the conditioning procedure.  (+info)

A classical model of memory developed in the 1960s assumed that all memories pass from a short-term to a long-term store after a small period of time. This model is referred to as the modal model and has been most famously detailed by Atkinson and Shiffrin (1968). The exact mechanisms by which this transfer takes place, whether all or only some memories are retained permanently, and indeed the existence of a genuine distinction between the two stores, remain controversial topics among experts. One form of evidence, cited in favor of the separate existence of a short-term store comes from anterograde amnesia, the inability to learn new facts and episodes. Patients with this form of amnesia, typically caused by damage to the hippocampus, have intact ability to retain small amounts of information over short time scales (up to 30 seconds) but are dramatically impaired in their ability to form longer-term memories (a famous example is patient HM). This is interpreted as showing that the short-term ...
Focal damage to the fornices is uncommon and may be due to surgical removal of ventricular cysts and tumours.1 We report a case of bilateral fornix infarction with reduced fractional anisotropy values at 3 T after anterior communicating artery aneurysm clipping.. A healthy 33-year-old woman was admitted to our hospital with the incidental finding of an anterior communicating artery (ACoA) aneurysm on magnetic resonance angiography. Neurological examination was normal. Digital subtraction angiography visualised a broad based, tapered and 4 mm sized aneurysm of the ACoA and a median callosal artery (fig 1C). The ACoA aneurysm was treated with surgical clipping because of its irregular configuration. After surgery, the patient was drowsy with fluctuating impaired vigilance. She was disoriented in time, space and person, and revealed anterograde amnesia and amnesic aphasia. Her relatives noticed personality changes, psychomotor slowing and decreased spontaneity of speech and behaviour. Apart from ...
This fact was made most famously clear in the case of patient Henry Molaison (H.M.) who post-operatively was unable to form new episodic memories (anterograde amnesia). He was henceforth only living in the present moment, unable to recall past or recent episodes in his life, though he maintained his pre-operative semantic knowledge of himself and the world. Another patient, Clive Wearing, was afflicted with encephalitis that destroyed most of his hippocampus and fornix fibers connecting the hippocampus to the neocortex. Consequently, he is unable to remember anything as recent as 30 seconds ago, though he still manages to play the piano beautifully (see also the article by Oliver Sacks, and the excellent film, Memento, by Christopher Nolan).. While there is still debate regarding the extent to which the hippocampus is necessary for the maintenance of stored information, the general view of hippocampal function resulting from these and a number of animal studies, is that the hippocampus is ...
In 2012, when a 22-year-old man showed up at a hospital in Boston suburb complaining of memory loss and extreme confusion following a possible opioid overdose, doctors were quick to diagnose him with an inability to form new memories, known as anterograde amnesia. The lead neurologist, who examined the man at that time, observed something strange in his brain scan report. The two seahorse-shaped structures of the patients hippocampi appeared lit up in contrast to the dark background of the rest of the brain. The neurologist concluded it was the impact of chronic injury to that part of the brain.. Although neurologists were aware that the hippocampi could change short-term memories into permanent ones, they couldnt provide a clear reason for the partial damage to the mans brain. In the months that followed, the doctors in the hospital came to know that opioids had a role to play in the mans memory loss. Moreover, the case became even more acute in the next three years, when three more ...
Although psychologists and neurologists have been familiar with the case of H.M. for years, this small volume makes his story-and what it can teach us about the functioning of memory-accessible to a much wider audience. Hilts has done a good job of piecing together H.M.s early life, in the absence of any living relatives and all but a few written records. He recreates the life of a very normal youth in the 1930s and 1940s; normal, that is, until H.M.s first epileptic seizure. In 1954, after several other treatments for the epilepsy had failed, H.M. (at age 27) had a bilateral medial temporal lobectomy, in the hope that it would alleviate his seizures. A neurosurgeon removed large sections of both temporal lobes, as well as much of the limbic system, including the amygdala and hippocampus. Since the surgery, H.M.-who was still alive when the book was written-suffers from a pervasive anterograde amnesia. In particular, H.M. has contributed greatly to our understanding of the neuroanatomy of memory and

Drinking enough alcohol to cause a blood alcohol concentration (BAC) of 0.03-0.12% typically causes a flushed, red appearance in the face and impaired judgment and fine muscle coordination. A BAC of 0.09% to 0.25% causes lethargy, sedation, balance problems and blurred vision. A BAC from 0.18% to 0.30% causes profound confusion, impaired speech (e.g., slurred speech), staggering, dizziness and vomiting. A BAC from 0.25% to 0.40% causes stupor, unconsciousness, anterograde amnesia, vomiting and respiratory depression (potentially life-threatening). A BAC from 0.35% to 0.80% causes a coma (unconsciousness), life-threatening respiratory depression and possibly fatal alcohol poisoning. There are a number of factors that affect when your BAC will reach or exceed 0.08, including how much you weigh the time frame that you been drinking and if you ate within the time of drinking. A 170 lbs male can drink more than a 135 lbs female, before being over the BAC level. [13] A breathalyzer is a device for ...
Drinking enough alcohol to cause a blood alcohol concentration (BAC) of 0.03-0.12% typically causes a flushed, red appearance in the face and impaired judgment and fine muscle coordination. A BAC of 0.09% to 0.25% causes lethargy, sedation, balance problems and blurred vision. A BAC from 0.18% to 0.30% causes profound confusion, impaired speech (e.g., slurred speech), staggering, dizziness and vomiting.

English version of clinical summary. Echinococcosis is an uncommon parasitic disease in Brazil, and manifestations are mainly pulmonary and hepatic. The central nervous system is involved is less than 2% of cases, the meningoencephalitic form being distinctly rare. This 67-year-old man presented with a 4-month history of cognitive decline (anterograde amnesia for recent facts and apathy). On the day before, he complained of headache, vomit, fever and confusion. On admission there was right hemiparesis (attributed to a cerebrovascular accident in 1994), lack of external ocular movements, uneven but light reacting pupils and meningoradicular signs. No papilledema was found. In 1997 he presented a left ventricle myocardial lesion which on biopsy proved to be an echinococcus cyst. Routine laboratory tests were normal. A suboccipital cerebrospinal fluid sample disclosed 95 cells/mm3 (60% neutrophils, 39% lymphocytes and 1% eosinophils); 61,800 red blood cells/mm3, protein levels of 268 mg/dl and low ...

ECT causes three types of memory impairment: an acute-confusional state, anterograde amnesia, and retrograde amnesia. The acute-confusional state is characterized by patient confusion due to the seizure and general anesthesia. That impairment typically lasts 20-30 minutes and subsides by the time patients leave the hospital. Patients are brought to a recovery room in order to wake up in an unstimulating environment because of this impairment. Anterograde amnesia is the disruption of memory function during the course of ECT treatment. If, for example, patients are receiving ECT three times a week for 3 weeks of treatment, they will have difficulty remembering and recording memories during that time. Anterograde amnesia dissipates over approximately 1-2 weeks after the end of the ECT course with memory functioning returning to normal. For that reason, patients cannot drive for approximately 1 week after their course of ECT, and certainly not during ECT treatment. Retrograde amnesia is the erasure ...

NMDA-receptor antagonist, is a relatively new drug specially developed for use in moderate-to-severe dementia. This drug may also be effective in the treatment of Korsakoffs amnestic syndrome. We report a case of a 45-year-old woman with WKS, who was treated with 20 mg memantine (Axura) daily for the period of 28 weeks. The patients cognitive status was evaluated using the following tests: mini-mental state examination (MMSE), Buschke selective reminding test, trail making test and Rey-Osterrieth complex figure test. No significant improvement was observed in the patients anterograde amnesia. Larger trials are needed to substantiate the efficacy of memantine for treatment of memory impairment in Korsakoffs syndrome.. ...
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. ...

The anterior thalamic nuclei (ATN), a central component of Papez circuit, are generally assumed to be key constituents of the neural circuits responsible for certain categories of learning and memory. Supporting evidence for this contention is that damage to either of two brain regions, the medial temporal lobe and the medial diencephalon, is most consistently associated with anterograde amnesia. Within these respective regions, the hippocampal formation and the ATN (anteromedial, anteroventral, and anterodorsal) are the particular structures of interest. The extensive direct and indirect hippocampal-anterior thalamic interconnections and the presence of theta-modulated cells in both sites further support the hypothesis that these structures constitute a neuronal network crucial for memory and cognition. The major tool in understanding how the brain processes information is the analysis of neuronal output at each hierarchical level along the pathway of signal propagation coupled with ...
Background Isoflurane can induce anterograde amnesia. Hippocampal ripples are high-frequency oscillatory events occurring in the local field potentials of cornu ammonis 1 involved in memory processes. The authors hypothesized that isoflurane suppresses hippocampal ripples at a subanesthetic concentration by modulating the excitability of cornu ammonis 1 neurons. Methods The potencies of isoflurane for memory impairment and anesthesia were measured in mice. Hippocampal ripples were measured by placing recording electrodes in the cornu ammonis 1. Effects of isoflurane on the excitability of hippocampal pyramidal neurons and interneurons were measured. A simulation model of ripples based on the firing frequency of hippocampal cornu ammonis 1 neurons was used to validate the effects of isoflurane on neuronal excitability in vitro and on ripples in vivo . Results Isoflurane at 0.5%, which did not induce loss of righting reflex, impaired hippocampus-dependent fear memory by 97.4 ± 3.1% (mean ± SD; n ...

Errorless learning has proven to be an effective method for (re)learning tasks in several patient groups with amnesia. However, so far only a handful of studies have examined the effects of errorless learning in patients with Korsakoffs syndrome. The aims of this feasibility study were to (a) examine the effects of errorless learning training on (re)learning tasks in a patient with Korsakoffs syndrome, (b) examine the effects of the nature of the training on the execution of the tasks, and (c) examine characteristics that may mediate learning outcome. Professional caregivers, who were trained in errorless learning principles, taught 51 patients with Korsakoffs syndrome two everyday tasks. Significant improvements in the performance were found after an errorless intervention for different types of trained tasks (activities of daily living, chores, mobility, housekeeping). Moreover, the results of this study suggest that all patients, despite of age, educational level, or level of cognitive ...

The functional contribution of medial temporal lobe has been studied in the human brain for over half a century. Insight into the nature of this extraordinary structure was discovered when epileptic patient H.M. had an experimental operation to surgically resect his bilateral medial temporal lobes. The procedure resulted in profound anterograde amnesia, demonstrating the critical role of medial temporal lobe in forming new long-term memories; yet a variety of other capacities remained intact (e.g., intelligence, personality, and skills). The notion that medial temporal lobe function was isolated to the formation of new long-term memories persisted for several decades until the development of new methodologies. It has been the endeavor of cognitive neuroscience to further our understanding of the structural organization of complex cognition and behavior. The focus of this dissertation is to provide evidence supporting the functional contribution of medial temporal lobe sub-regions, namely ...

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.. AB - The ...
BACKGROUND: Subclinical doses of propofol produce anterograde amnesia, characterized by an early failure of memory consolidation. It is unknown how propofol affects the amygdala-dependent emotional memory system, which modulates consolidation in the hippocampus in response to emotional arousal and neurohumoral stress. We present an event-related functional magnetic resonance imaging study of the effects of propofol on the emotional memory system in human subjects.. METHODS: Thirty-five healthy subjects were randomized to receive propofol, at an estimated brain concentration of 0.90 μg ml(-1), or placebo. During drug infusion, emotionally arousing and neutral images were presented in a continuous recognition task, while blood-oxygen-level-dependent activation responses were acquired. After a drug-free interval of 2 h, subsequent memory for successfully encoded items was assessed. Imaging analysis was performed using statistical parametric mapping and behavioural analysis using signal detection ...
Alcohol dependence and alcohol abuse or harmful use cause substantial morbidity and mortality. Alcohol-use disorders are associated with depressive episodes, severe anxiety, insomnia, suicide, and abuse of other drugs. Continued heavy alcohol use also shortens the onset of heart disease, stroke, cancers, and liver cirrhosis, by affecting the cardiovascular, gastrointestinal, and immune systems. Heavy drinking can also cause mild anterograde amnesias, temporary cognitive deficits, sleep problems, and peripheral neuropathy; cause gastrointestinal problems; decrease bone density and production of blood cells; and cause fetal alcohol syndrome. Alcohol-use disorders complicate assessment and treatment of other medical and psychiatric problems. Standard criteria for alcohol dependence-the more severe disorder-can be used to reliably identify people for whom drinking causes major physiological consequences and persistent impairment of quality of life and ability to function. Clinicians should routinely ...
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
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.

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. ...

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.

TY - JOUR. T1 - Rab1 interacts directly with the β2-adrenergic receptor to regulate receptor anterograde trafficking. AU - Hammad, Maha. AU - Kuang, Yi Qun. AU - Morse, Alexa. AU - Dupré, Denis J.. PY - 2012/5/1. Y1 - 2012/5/1. N2 - Very little is understood about the trafficking of G protein-coupled receptors (GPCRs) from the endoplasmic reticulum (ER) to the plasma membrane. Rab guanosine triphosphatases (GTPases) are known to participate in the trafficking of various GPCRs via a direct interaction during the endocytic pathway, but whether this occurs in the anterograde pathway is unknown. We evaluated the potential interaction of Rab1, a GTPase known to regulate β2-adrenergic receptor (β2AR) trafficking, and its effect on export from the ER. Our results show that GTP-bound Rab1 interacts with the F(x) 6LL motif of β2AR. Receptors lacking the interaction motif fail to traffic properly, suggesting that a direct interaction with Rab1 is required for β2AR anterograde trafficking.. AB - Very ...
