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 ...
TY - JOUR. T1 - Aluminum Has Both Oxidant and Antioxidant Effects in Mouse Brain Membranes. AU - Oteiza, Patricia I. AU - Fraga, C. G.. AU - Keen, C. L.. PY - 1993/1. Y1 - 1993/1. 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.

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 ...

The long term objective of this project is to develop an understanding of lifestyle factors that influence the cognitive and brain health of children while also reducing the sedentary nature of todays youth. Previous research has found that physical activity interventions can enhance both a variety of aspects of cognition and brain structure and function of children, older adults, and individuals with neurodegenerative disorders such as Parkinsons disease and multiple sclerosis. More specifically, in previous research with children the researchers have found that higher fit children possess larger hippocampi which in turn are related to better relational memory than their lower fit counterparts. The researchers have also observed that higher fit children exhibit more efficient executive control as indicated by performance measures and event-related brain potentials. While intriguing, these cross-sectional data do not enable us to establish causality between physical activity and cognition. In ...
Recording the neural activity of monkeys as they plan to reach, or just react, will help engineers design better brain-controlled prosthetic limbs.. Ready, set, go.. Sometimes thats how our brains work. When we anticipate a physical act, such as reaching for the keys we noticed on the table, the neurons that control the task adopt a state of readiness, like sprinters bent into a crouch.. Other times, however, our neurons must simply react, such as if someone were to toss us the keys without gesturing first.. How do the neurons in the brain control planned versus unplanned arm movements?. Krishna Shenoy, a Stanford professor of electrical engineering, wanted to answer that question as part of his groups ongoing efforts to develop and improve brain-controlled prosthetic devices.. In a paper published in the journal Neuron, Shenoy and first author Katherine Cora Ames, a doctoral student in the Neurosciences Graduate Program, present a mathematical analysis of the brain activity of monkeys as they ...
A national team of researchers led by investigators at the University of California, San Diego School of Medicine have developed a multidimensional set of brain measurements that, when taken together, can accurately assess a childs age with 92 percent accuracy.. We have uncovered a developmental clock within the brain-a biological signature of maturation that captures age differences quite well regardless of other kinds of differences that exist across individuals, said first author Timothy T. Brown, PhD, a developmental cognitive neuroscientist in the Department of Neurosciences at UC San Diego School of Medicine.. This study of the anatomy of the developing human brain, to be published in the September 25 print edition of Current Biology, addresses a long-standing scientific question about individual biological variability in children. It shows that, for certain structural measures, maturational differences in the developing human brain are much smaller than was previously thought - ...

Tiny spheres of human cells mimic the brain, researchers say.. Researchers have figured out how to create spheres of neuronal cells resembling the cerebral cortex, making functional human brain tissue available for the first time to study neuropsychiatric diseases such as autism and schizophrenia.. The human brain is a highly organized, three-dimensional mass of cells responsible for our every move, thought and emotion. Snugly housed in the bony confines of the skull, its also relatively inaccessible, making it difficult to study.. Now, researchers at the Stanford University School of Medicine have devised a way to generate spherical, free-floating balls of human brain cells that mimic the architecture of the cerebral cortex, the outer layer of brain tissue responsible for how we experience and perceive the world around us and how we interact with others. The spheres contain functional neurons, working synapses and even critical support cells called astrocytes that maintain neural function. ...
Connections in the brain of a healthy 29 year old female human viewed from the front, face on (anterior view). The top of the brain is at the top of the image. Brain cells communicate with each other through these nerve fibres, which have been visualised using diffusion imaging tractography. Diffusion weighted imaging is a specialised type of magnetic resonance imaging (MRI) scan which measures water diffusion in many directions in order to reconstruct the orientation of bundles of axons. Tractography is used to indirectly model these bundles of axons (nerve fibres), which transmit information between cortical regions at the brains surface. For example, the bundles of fibres (tracts) closest to the viewer are travelling to the frontal lobe of the brain. Connections travelling from the corticospinal tract to the motor cortex are visible in blue/purple. The brain measures approximately 18 cm from front to back.
