Protein shown to rally biological clock
A biologist at Washington University in St. Louis and his collaborators have identified the factor in mammalian brain cells that keeps cells in synchrony so that functions like the wake-sleep cycle, hormone secretion and loco motor behaviors are coordinated daily over a 24-hour period.   view more (2006-11-30)

Scientists identify fundamental brain defect, probable drug target in fragile X syndrome
Scientists have discovered how the gene mutation responsible for fragile X syndrome--the most common inherited form of mental retardation--alters the way brain cells communicate.   view more (2007-09-18)

UC Davis M.I.N.D. Institute researchers find fewer neurons in the amygdala of males with autism
Researchers at the University of California, Davis, M.I.N.D. Institute have discovered that the brains of males with autism have fewer neurons in the amygdala, a part of the brain involved in emotion and memory.   view more (2006-07-19)

Researchers discover second depth-perception method in brain
It's common knowledge that humans and other animals are able to visually judge depth because we have two eyes and the brain compares the images from each. But we can also judge depth with only one eye, and scientists have been searching for how the brain accomplishes that feat.   view more (2008-03-17)

Protein shown to play a key role in normal development of nervous system
A protein that enables nerve cells to communicate with each other plays a key role in controlling the developing nervous system.   view more (2008-10-08)

Brandeis researchers propose model of neural circuit underlying working memory
Our ability to understand speech or decide which fruit in the store is freshest depends on the brain's dexterity in integrating information over time.   view more (2005-12-21)

Discovery of post-stimulus activated release implies new mechanisms for dopamine release
The neurotransmitter dopamine continues to be released for nearly an hour after neurons are stimulated, suggesting the existence of secondary mechanisms that allow for sustained availability of dopamine in different regions of the brain including areas critical for memory consolidation, drug... view more (2006-10-16)

Researchers develop targeted approach to pain management
Imagine an epidural or a shot of Novocain that doesn't paralyze your legs or make you numb, yet totally blocks your pain.   view more (2007-10-04)

A resetting signal keeps circadian rhythm on track in Drosophila fruit flies
A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies).   view more (2005-11-10)

New understanding of nervous system gives insight into common gut problem in newborn babies
Medical Research Council (MRC) researchers have unlocked the mysteries of the nervous system responsible for proper formation and function of the gut. This new understanding has implications for treating Hirschsprung's disease, a common disorder in newborns that requires corrective surgery in order... view more (2003-12-03)

Researchers reveal types of genes necessary for brain development
Researchers from Harvard Medical School and Brandeis University have successfully completed a full-genome RNAi screen in neurons, showing what types of genes are necessary for brain development. Details of the screen and its novel methodology are published July 4th in the open-access journal PLoS... view more (2008-07-08)

Lou Gehrig's protein found throughout brain, suggesting effects beyond motor neurons
Two years ago researchers at the University of Pennsylvania School of Medicine discovered that misfolded proteins called TDP-43 accumulated in the motor areas of the brains of patients with amyotropic lateral sclerosis (ALS), or Lou Gehrig's disease.   view more (2008-06-17)

Key brain antioxidant linked to Alzheimer's and Parkinson's
A study conducted at the San Francisco VA Medical Center has identified a protein found in both mice and humans that appears to play a key role in protecting neurons from oxidative stress, a toxic process linked to neurodegenerative illnesses including Alzheimer's and Parkinson's diseases.   view more (2005-12-15)

Understanding Fragile X syndrome with the blink of an eye
While researchers have long known the genetic defect underlying Fragile X syndrome, they are still tracing how that defect creates the complex mix of mental retardation, hyperactive behavior, attention deficits, and other problems in the disorder.   view more (2005-08-04)

Alzheimer's disease progresses more rapidly in highly educated people
High levels of education may help ward off Alzheimer's disease, but they also speed up its progression once developed, reveals research in the Journal of Neurology Neurosurgery and Psychiatry.   view more (2006-02-16)

UCR researchers show how the brain turns on innate behavior
UCR researchers have made a major leap forward in understanding how the brain programs innate behavior.   view more (2006-07-28)

'Lab on a chip' mimics brain chemistry
Johns Hopkins researchers from the Whiting School of Engineering and the School of Medicine have devised a micro-scale tool - a lab on a chip - designed to mimic the chemical complexities of the brain. The system should help scientists better understand how nerve cells in the brain work together to... view more (2008-02-13)

Case biologists show that what a neuron can do is a function of mechanical context
The brain as command center for bodily movement was too simple an idea, thought the Russian physiologist Nicolas Bernstein some 60 years ago.   view more (2006-02-08)

Stem cell research aims to tackle Parkinson's disease
Scientists in Sweden are developing new ways to grow brain cells in the laboratory that could one day be used to treat patients with Parkinson's disease, an international conference of biologists organised by the European Science Foundation (ESF) was told last week.   view more (2008-01-21)

Fatty diet during pregnancy makes new cells in fetal brain that cause early onset obesity
A study in rats shows that exposure to a high-fat diet during pregnancy produces permanent changes in the offspring's brain that lead to overeating and obesity early in life, according to new research by Rockefeller University scientists.   view more (2008-11-12)

Agent Protects Parkinson's Neurons from Rotenone Toxicity
Researchers at the University at Buffalo affiliated with the New York State Center of Excellence in Bioinformatics and Life Sciences have identified a novel agent that can protect neurons involved in Parkinson's disease from being destroyed by the pesticide rotenone.   view more (2006-04-19)

Insight into neural stem cells has implications for designing therapies
Scientists have discovered that adult neural stem cells, which exist in the brain throughout life, are not a single, homogeneous group.   view more (2007-07-09)

MIT researchers watch brain in action
For the first time, scientists have been able to watch neurons within the brain of a living animal change in response to experience.   view more (2006-07-31)

Neurons find their place in the developing nervous system with the help of a sticky molecule
The brain, that exquisite network of billions of communicating cells, starts to take form with the genesis of nerve cells. Most newborn nerve cells, also called neurons, must travel from their birthplace to the position they will occupy in the adult brain.   view more (2006-04-26)

Blood flow in brain takes a twist, affecting views of Alzheimer's
New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease.   view more (2006-01-06)
