The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.

A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Long-term effects of N-2-chlorethyl-N-ethyl-2-bromobenzylamine hydrochloride on noradrenergic neurones in the rat brain and heart. (1/63334)

1 N-2-Chlorethyl-N-ethyl-2-bromobenzylamine hydrochloride (DSP 4) 50 mg/kg intraperitoneally, produced a long-term decrease in the capacity of brain homogenates to accumulate noradrenaline with significant effect 8 months after the injection. It had no effect on the noradrenaline uptake in homogenates from the striatum (dopamine neurones) and on the uptake of 5-hydroxytryptamine (5-HT) in various brain regions. 2 In vitro DSP 4 inhibited the noradrenaline uptake in a cortical homogenate with an IC50 value of 2 muM but was more than ten times less active on the dopamine uptake in a striatal homogenate and the 5-HT uptake in a cortical homogenate. 3 DSP 4 (50 mg/kg i.p.) inhibited the uptake of noradrenaline in the rat heart atrium in vitro but this action was terminated within 2 weeks. 4 DSP 4 (50 mg/kg i.p.) cuased a decrease in the dopamine-beta-hydroxylase (DBH) activity in the rat brain and heart. The onset of this effect was slow; in heart a lag period of 2-4 days was noted. In brain the DBH-activity in cerebral cortex was much more decreased than that in hypothalamus which was only slightly affected. A significant effect was still found 8 months after the injection. The noradrenaline concentration in the brain was greatly decreased for at least two weeks, whereas noradrenaline in heart was only temporarily reduced. 5 The long-term effects of DSP 4 on the noradrenaline accumulation, the DBH activity and noradrenaline concentration in the rat brain were antagonized by desipramine (10 mg/kg i.p.). 6 It is suggested that DSP 4 primarily attacks the membranal noradrenaline uptake sites forming a covalent bond and that the nerve terminals, as a result of this binding, degenerate.  (+info)

Studies on the mechanism of action of amantadine. (2/63334)

1 The effect of amantadine hydrochloride on various aspects of catecholamine metabolism in the rat brain has been investigated. 2 Amantadine failed to have any significant effect on brain concentrations of dopamine or noradrenaline even when administered daily for 9 days. 3 Amantadine had no effect on the rate of decline of noradrenaline and dopamine concentrations after alpha-methyl-p-tyrosine. 4 In vitro amantadine inhibited dopamine uptake into synaptosomes only at high concentrations, and caused little release of dopamine from synaptosomes. 5 There is no evidence from these results to suggest that the anti-Parkinsonian effect of amantadine is related to an action on dopaminergic mechanisms.  (+info)

Mercury and Mink. II. Experimental methyl mercury intoxication. (3/63334)

Adult female mink were fed rations containing 1.1, 1.8, 4.8, 8.3 and 15.0 ppm mercury as methyl mercury chloride over a 93 day period. Histopathological evidence of injury was present in all groups. Mink fed rations containing 1.8 to 15.0 ppm mercury developed clinical intoxication within the experimental period. The rapidity of onset of clinical intoxication was directly related to the mercury content of the ration. Mercury concentration in tissue of mink which died were similar, despite differences in mercury content of the diets and time of death. The average mercury concentration in the brain of mink which died was 11.9 ppm. The lesions of methyl mercury poisoning are described and criteria for diagnosis are discussed.  (+info)

Glycopeptides from the surgace of human neuroblastoma cells. (4/63334)

Glycopeptides suggesting a complex oligosaccharide composition are present on the surface of cells from human neuroblastoma tumors and several cell lines derived from the tumors. The glycopeptides, labeled with radioactive L-fucose, were removed from the cell surface with trypsin, digested with Pronase, and examined by chromatography on Sephadex G-50. Human skin fibroblasts, brain cells, and a fibroblast line derived from neuroblastoma tumor tissue show less complex glycopeptides. Although some differences exist between the cell lines and the primary tumor cells, the similarities between these human tumors and animal tumors examined previously are striking.  (+info)

Evaluating cost-effectiveness of diagnostic equipment: the brain scanner case. (5/63334)

An approach to evaluating the cost-effectiveness of high-technology diagnostic equipment has been devised, using the introduction of computerised axial tomography (CAT) as a model. With the advent of CAT scanning, angiography and air encephalography have a reduced, though important, role in investigating intracranial disease, and the efficient use of conventional equipment requires the centralisation of neuroradiological services, which would result in major cash savings. In contrast, the pattern of demand for CAT scanning, in addition to the acknowledged clinical efficiency of the scanner and its unique role in the head-injured patient, ephasies the need for improved access to scanners. In the interest of the patients the pattern of service must change.  (+info)

oko meduzy mutations affect neuronal patterning in the zebrafish retina and reveal cell-cell interactions of the retinal neuroepithelial sheet. (6/63334)

Mutations of the oko meduzy (ome) locus cause drastic neuronal patterning defect in the zebrafish retina. The precise, stratified appearance of the wild-type retina is absent in the mutants. Despite the lack of lamination, at least seven retinal cell types differentiate in oko meduzy. The ome phenotype is already expressed in the retinal neuroepithelium affecting morphology of the neuroepithelial cells. Our experiments indicate that previously unknown cell-cell interactions are involved in development of the retinal neuroepithelial sheet. In genetically mosaic animals, cell-cell interactions are sufficient to rescue the phenotype of oko meduzy retinal neuroepithelial cells. These cell-cell interactions may play a critical role in the patterning events that lead to differentiation of distinct neuronal laminae in the vertebrate retina.  (+info)

Visual perception: mind and brain see eye to eye. (7/63334)

Recent functional imaging studies have identified neural activity that is closely associated with the perception of illusory motion. The mapping of the mind onto the bin appears to be one-to-one: activity in visual 'motion area' MT is highly correlated with perceptual experience.  (+info)

Accelerated accumulation of somatic mutations in mice deficient in the nucleotide excision repair gene XPA. (8/63334)

Inheritable mutations in nucleotide excision repair (NER) genes cause cancer-prone human disorders, such as xeroderma pigmentosum, which are also characterized by symptoms of accelerated ageing. To study the impact of NER deficiency on mutation accumulation in vivo, mutant frequencies have been determined in liver and brain of 2-16 month old NER deficient XPA-/-, lacZ hybrid mice. While mutant frequencies in liver of 2-month old XPA-/-, lacZ mice were comparable to XPA+/-, lacZ and the lacZ parental strain animals, by 4 months of age mutant frequencies in the XPA-deficient mice were significantly increased by a factor of two and increased further until the age of 16 months. In brain, mutant frequencies were not found to increase with age. These results show that a deficiency in the NER gene XPA causes an accelerated accumulation of somatic mutations in liver but not in brain. This is in keeping with a higher incidence of spontaneous liver tumors reported earlier for XPA-/- mice after about 15 months of age.  (+info)

Term newborns with congenital heart disease have widespread brain abnormalities before they undergo cardiac surgery. The imaging findings in such newborns are similar to those in premature newborns and may reflect abnormal brain development in utero.
In late-onset Alzheimers disease (AD), multiple brain regions are not affected simultaneously. Comparing the gene expression of the affected regions to identify the differences in the biological processes perturbed can lead to greater insight into AD pathogenesis and early characteristics. We identified differentially expressed (DE) genes from single cell microarray data of four AD affected brain regions: entorhinal cortex (EC), hippocampus (HIP), posterior cingulate cortex (PCC), and middle temporal gyrus (MTG). We organized the DE genes in the four brain regions into region-specific gene coexpression networks. Differential neighborhood analyses in the coexpression networks were performed to identify genes with low topological overlap (TO) of their direct neighbors. The low TO genes were used to characterize the biological differences between two regions. Our analyses show that increased oxidative stress, along with alterations in lipid metabolism in neurons, may be some of the very early ...

Neuroanatomically precise, genome-wide maps of transcript distributions are critical resources to complement genomic sequence data and to correlate functional and genetic brain architecture. Here we describe the generation and analysis of a transcriptional atlas of the adult human brain, comprising extensive histological analysis and comprehensive microarray profiling of ∼900 neuroanatomically precise subdivisions in two individuals. Transcriptional regulation varies enormously by anatomical location, with different regions and their constituent cell types displaying robust molecular signatures that are highly conserved between individuals. Analysis of differential gene expression and gene co-expression relationships demonstrates that brain-wide variation strongly reflects the distributions of major cell classes such as neurons, oligodendrocytes, astrocytes and microglia. Local neighbourhood relationships between fine anatomical subdivisions are associated with discrete neuronal subtypes and genes

Given recent advances in technology, it isnt unusual for a previously paralyzed man or woman regaining the ability to walk thanks to manually-controlled robotic limbs, but now University of California-Irvine researchers have accomplished the feat without such aids.. In a preliminary proof-of-concept study, Dr. An Do, Dr. Zoran Nenadic and colleagues showed that it is possible to use direct brain control to allow a spinal cord injury patient to use his or her own legs to walk again without having to rely upon mechanical aids for locomotion.. The research, which was published in the Journal of NeuroEngineering and Rehabilitation, is said to mark the first time that direct brain control has enabled a person to walk without use of robotic devices following complete paralysis in both legs following a spinal cord injury.. The individual had been a paraplegic for five years, and thanks to an EEG-based brain control system, he was able to walk along a 3.66m long course 30 times over a 19 week span, the ...
Weve been hearing plenty about brain-based learning, but much of what we hear can be confusing. Not only are there arguments about how well brain-based learning works, there are arguments about whether such a thing such as brain-based learning exists at all.. Like so much other recent brain-related news, discussions about brain-based learning have been sparked by the boom in brain science over the past 15 years. With so much new information about the brain filtering into the mainstream, educators have been understandably eager to put to use in the classroom whatever they can.. The rush to use this information in the classroom, however, can be a problem and do more harm to education than good, says Dr. John Bruer, author of The Myth of the First Three Years and president of the James S. McDonnell Foundation, which supports research and education related to the brain. Brain science, says Bruer, can tell us very little about how the brain learns and it is far too early to take what we know at this ...

N2 - The in vitro effects of aluminum (A1) on lipid peroxidation were studied in mouse brain homogenates and purified brain subcellular fractions. In brain homogenates prepared in 5 mM Na2HPO4, 0.14 M NaCl, pH 7.4, the addition of Al decreased Fe2+-induced lipid peroxidation, measured as 2-thiobarbituric acid- reactive substances (TBARS), in a dose dependent manner, with a maximum effect at 250 μM Al. In brain homogenates prepared in 20 mM Tris-HCI, 0.14 M NaCl, pH 7.4, Al acted as a prooxidant at 250 and 500 μM concentrations. The prooxidant effect of Al was enhanced with increasing concentrations of Fe2+. In brain microsonies Al increased TBARS production and conjugated dienes formation, both depending on the addition of Fe2+. In myelin, the prooxidant effect of Al on Fe2+-induced lipid peroxidation was eliminated ...

The hippocampus is one of the earliest and most affected regions in Alzheimers disease (AD), followed by the cortex while the cerebellum is largely spared. Importantly, endothelial dysfunction is a common feature of cerebral blood vessels in AD. In this study, we sought to determine if regional heterogeneity of cerebral microvessels might help explain the susceptibility of the hippocampus and cortex as compared to the cerebellum. We isolated microvessels from wild type mice from the cerebellum, cortex, and hippocampus to characterize their vascular phenotype. Superoxide anion was significantly higher in microvessels isolated from the cortex and hippocampus as compared to the cerebellum. Importantly, protein levels of NADPH oxidase (NOX)-2 and NOX-4 were significantly higher in the cortical and hippocampal microvessels as compared to microvessels from the cerebellum. In addition, expression of manganese superoxide dismutase protein was significantly lower in microvessels from the cortex and hippocampus
The method researchers used to assess brain atrophy across 25 published studies, called colocalization-likelihood estimation (CLE), was developed by Peter E. Turkeltaub, MD, PhD, an associate professor of neurology at Georgetown and a co-author of the study.. The researchers found that the frontal region (including anterior cingulate cortex, or ACC) is the most frequently affected brain region in HIV+ adults, whereas the neural injury to the caudate/striatum was consistently linked to neurocognitive impairment.. These results suggest a two-stage model of HAND in the context of brain atrophy, with a frontal/ACC stage that links to HIV disease and likely other comorbidities, such as substance abuse, and a caudate/striatum stage that links to neurocognitive impairment. These two areas likely play different roles in HAND, Jiang says.. It is our theory, and others, that the frontal/ACC area damage is due to a number of factors, but which importantly includes damage to the dopaminergic region, he ...

Research by a UConn neurobiologist has demonstrated that a developmental brain disorder that causes a predisposition to seizures can be reversed.. The research, by a team led by Joseph LoTurco, a professor of physiology and neurobiology in the College of Liberal Arts and Sciences, was the cover article in the January issue of the biomedical research journal Nature Medicine.. We showed that adding back a normal gene in a brain that has already developed the wrong way can reverse a previously formed developmental malformation, LoTurco says.. The cerebral cortex is a structure within the brain that plays a key role in memory, attention, perception, thought, and language. Its layered structure is formed during development by the migration of neurons.. The researchers focused on a malformation that happens early in fetal development that is a known risk factor for epilepsy. The malformation is linked to mutations in a certain gene known as Dcx or doublecortin. LoTurco says patients who have a ...

Now, writing in the journal Cell Stem Cell (July 1, 2010), a team of scientists from the University of Wisconsin-Madison has identified a single gene that seems to be a master regulator of human brain development, guiding undifferentiated stem cells down tightly defined pathways to becoming all of the many types of cells that make up the brain.. The new finding is important because it reveals the main genetic factor responsible for instructing cells at the earliest stages of embryonic development to become the cells of the brain and spinal cord. Identifying the gene - known as Pax6 - is a first critical step toward routinely forging customized brain cells in the lab.. Whats more, the work contrasts with findings from animal models such as the mouse and zebrafish, pillars of developmental biology, and thus helps cement the importance of the models being developed from human embryonic stem cells.. The new work, conducted in the Waisman Center laboratory of UW-Madison neuroscientist Su-Chun Zhang, ...
TY - JOUR. T1 - The role of nutrition on cognition and brain health in ageing. T2 - A targeted approach. AU - Monti, Jim M.. AU - Moulton, Christopher J.. AU - Cohen, Neal J.. PY - 2015/10/15. Y1 - 2015/10/15. N2 - Animal experiments and cross-sectional or prospective longitudinal research in human subjects suggest a role for nutrition in cognitive ageing. However, data from randomised controlled trials (RCT) that seek causal evidence for the impact of nutrients on cognitive ageing in humans often produce null results. Given that RCT test hypotheses in a rigorous fashion, one conclusion could be that the positive effects of nutrition on the aged brain observed in other study designs are spurious. On the other hand, it may be that the design of many clinical trials conducted thus far has been less than optimal. In the present review, we offer a blueprint for a more targeted approach to the design of RCT in nutrition, cognition and brain health in ageing that focuses on three key areas. First, the ...
By David J. Ostry (Professor, Psychology, McGill) We frequently think of neuroplasticity in the human brain in the context of the developmental and maturational changes that occur in the brain and behaviour during childhood. Luckily, for those of us that are no longer children, the adult human brain remains remarkably plastic. A facet of this plasticity that has important clinical applications is that changes occur in both sensory and motor systems of the brain with surprisingly brief periods of training. I will tell you about a series of recent studies in my laboratory, where we see that the effects of motor learning spill over into sensory systems, and that perceptual learning may provide us with a back door to the motor system that can be exploited in therapeutic interventions. Dr. Ostrys research focuses on understanding the biological mechanisms of voluntary movement and deals equally with speech production and human arm motion. His lab uses mathematical models, robots and behavioral and

Experiments with rabbits, cats, and monkeys during recording of complex physiological processes (LEPG, ThG, Po2, Pco2, and ECoG) in functionally discrete brain regions of awake animals have shown that functional changes, expressed as desynchronization effects on ECoG, are followed by an increase of local blood flow (LCBF) in regional brain cortex up to 0.3 to 0.4 ml per minute per 1 gm brain tissue or an increase of 35% to 45% of resting levels of LCBF. Under normal physiological conditions LCBF and Po2 change periodically without any external interference at frequency ranges 0.005 to 0.2 cps. This is characteristic of all brain regions and all species of animals investigated. These variations range in amplitude as much as 28% of the mean level of LCBF.. Changes of LCBF have no correlation with changes of systemic blood pressure (SAP). Local control mechanisms appear to be responsible for them. The interrelationships of changes of functional activity and CBF in local regions of awake brain are ...

Hello, I have some sample of rat brain which is not perfused with any fixitive before. The tissue is profixed in 4% paraformaldehyde for a week and then processed for paraffin section. But when the section is cut, it expands and breaks when float in water. Does anyone know why this happen and can give suggestion for the protocol? I also have rat brain when received 4% PFA perfucion before dissected out. These whole rat brain is profixed in fixitive overnight and then dehydrated with alcohol, again, after xylene and wex embedding, it breaks up when cut into 8 micron section. Does anyone can give me some suggestions on the protocol? Thanks a lot.

Keep in mind, in contrast to most other body organs, your brain cannot fix itself. Exploration considers have indicated that Parkinsons illness, a sensory system malady, is brought about by outside synthetic substances and neurotoxic toxins. As per an article distributed in the Journal of the American Association, ecological synthetic concoctions and neurotoxic toxins are answerable for some instances of Parkinsons sickness.. Food decision is critical to brain health in light of the fact that the food you eat today is not the same as that devoured by your progenitors.

Summary: By optimizing neurons with CRISPR gene editing technology, researchers will have new ways to study genetic influences on brain health and disease, a new study reports.. Source: SfN.. Neuroscientists have used CRISPR/Cas9 genome editing technology to regulate genes in the rat brain. Described in eNeuro, this technique paves the way for researchers to probe genetic influences on brain health and disease in model organisms that more closely resemble human conditions... Studying genes in the brain is expensive and time-consuming, often relying on transgenic animals, such as fruit flies and mice, designed to assess one gene at a time. Despite rapid advances in the development of powerfully precise CRISPR/Cas9 systems, adapting these for use in the central nervous system has proved challenging.. A neuron-optimized CRISPR activation system developed by Jeremy Day and colleagues overcomes these challenges. The researchers demonstrate both in diverse cultured cells and in multiple regions of the ...

We know that high levels of amyloid-beta plaques are characteristic of Alzheimers, but we also know that people can have high levels of amyloid without displaying symptoms of Alzheimers. A new study shows that the reason for this apparent discrepancy may lie with another protein, called NPTX2.. It appears that memory loss occurs when high amyloid-beta occurs in combination with low levels of NPTX2.. The gene which expresses the protein NPTX2 belongs to a set of genes known as immediate early genes, which are activated almost instantly in brain cells when an experience results in a new memory. The protein is used by neurons to strengthen the circuits that encode memories.. A study of 144 archived human brain tissue samples revealed that NPTX2 protein levels were reduced by as much as 90% in brain samples from people with Alzheimers compared with age-matched brain samples without Alzheimers. People with amyloid plaques who had never shown signs of Alzheimers, on the other hand, had normal ...
Immunohistochemical analysis of human brain samples represents an alternative approach for neurogenesis experiments in adult humans [32]. Based on our results, we recommend that the time between death and tissue fixation does not exceed 16 h when devising an immunohistochemistry protocol to study neurogenesis markers in adult humans; thus, the development of a rapid autopsy program [33-35] is desirable. In the indirect immunofluorescence protocol, we noticed that better nestin staining was achieved when the primary antibody solution was maintained on the slides for 48 h at 4°C (Additional file 1: Table S1) [36] instead of overnight at room temperature (data not shown); this finding should be taken into consideration when troubleshooting poor staining of human brain samples.. A caveat of our results is that the staining may not identify a neurogenic system. Indeed, the streptavidin-biotin method revealed biotin staining in negative controls in major bundles such as the fimbria-fornix. To avoid ...
