U-M professor shows how plasticity of brain restores critical functions related to learning, memory

When Geoffrey Murphy, Ph.D., talks about plastic structures, he's not talking about the same thing as Mr. McGuire in The Graduate. To Murphy, an associate professor of molecular and integrative physiology at the University of Michigan Medical School, plasticity refers to the brain's ability to change as we learn.

Researchers discover a type of 'cellular bilingualism' in brain

A team of researchers from the University of Montreal and McGill University have discovered a type of "cellular bilingualism" - a phenomenon that allows a single neuron to use two different methods of communication to exchange information.

Researchers develop diagnostic test for motor neurone disease

NeuRA researchers are one step closer to developing a diagnostic test for motor neurone disease. Dr Steve Vucic, from Neuroscience Research Australia, says the test will allow people with motor neurone disease to be diagnosed up to eight months earlier than is currently possible.

Low calorie diet may delay or prevent aging and neurodegenerative diseases

Cells, which employ a process called autophagy to clean up and reuse protein debris leftover from biological processes, were the original recyclers. A team of scientists from Paul Greengard's Rockefeller University laboratory have linked a molecule that stimulates autophagy with the reduction of one of Alzheimer's disease's major hallmarks, amyloid peptide.

Blind people's brains rewire part of mind associated with sight to process sound

Dr. Olivier Collignon of the University of Montreal's Saint-Justine Hospital Research Centre compared the brain activity of people who can see and people who were born blind, and discovered that the part of the brain that normally works with our eyes to process vision and space perception can actually rewire itself to process sound information instead.

Decades-old FDA approved hypertension drug may delay onset and reduce severity of MS

People suffering from multiple sclerosis may benefit if patent-pending research conducted at Purdue University shows that a decades-old drug approved by the FDA to treat hypertension also delays the onset and reduces the severity of MS symptoms.

Bonding with mom develops over first few weeks of life in rodent pups

For rodent pups, bonding with mom isn't hard-wired in the womb. It develops over the first few weeks of life, which is achieved by their maturing sense of smell, possibly allowing these mammals a survival advantage by learning to identify mother, siblings, and home.

New research: Rhodopsin pigment in Drosophila may detect temperature

New research from Mount Sinai School of Medicine has discovered that rhodopsin, a pigment of the retina that is responsible for the first events in the perception of light, may also be involved in temperature sensation. This detection had not been revealed in previous studies.

Study identifies potential therapeutic target for neurodegenerative disorders

Cell biologists pondering the death of neurons - brain cells - said today that by eliminating one ingredient from the cellular machinery, they prolonged the life of neurons stressed by a pesticide chemical. The finding identifies a potential therapeutic target to slow changes that lead to neurodegenerative disorders such as Parkinson's and Alzheimer's diseases.

New technique may find 'hidden' receptors in nerve cells

Scientists at The Scripps Research Institute and University of Pennsylvania have found a way to uncover potential drug targets that have so far remained hidden from researchers' view.

Neurogenesis plays a beneficial role in exercise-induced response to stress, sexual behavior and reproduction

Two studies published by an interdisciplinary team of Hong Kong researchers in the current special issue of Cell Transplantation (20:1), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/ , link the regrowth of key adult brain cells (neurogenesis) in two critical areas of the brain to both the benefits of exercise as a stress reducer and also to sexual behavior and reproductive issues.

Study sheds light on how signals from CSF help drive neural development

Cerebrospinal fluid, the fluid found in and around the brain and spinal cord, may play a larger role in the developing brain than previously thought, according to researchers at Children's Hospital Boston.

Scientists develop new model for neurodegenerative disease

A team of scientists at the University of California, San Francisco has developed a new model for how inherited genes contribute to a common but untreatable and incurable neurodegenerative disease.

Caspase inhibition can prevent brain inflammation in neurological diseases

Neurodegenerative diseases like Alzheimer's and Parkinson's are partly attributable to brain inflammation. Researchers at Karolinska Institutet now demonstrate in a paper published in Nature that a well-known family of enzymes can prevent the inflammation and thus constitute a potential target for drugs.

New study sheds 'light' on intricate brain cell connections responsible for anxiety

A new study sheds light--both literally and figuratively--on the intricate brain cell connections responsible for anxiety.

Mother's poor or inadequate nutrition linked to overeating later in life

Providing further understanding of the link between low birth weights and obesity later in life, researchers found nutritionally deprived newborns are "programmed" to eat more because they develop less neurons in the region of the brain that controls food intake, according to an article published today in the journal, Brain Research.

Study finds synapses between retinal ganglion cells and starburst amacrine cells distributed asymmetrically

The sensory cells in the retina of the mammalian eye convert light stimuli into electrical signals and transmit them via downstream interneurons to the retinal ganglion cells which, in turn, forward them to the brain. The interneurons are connected to each other in such a way that the individual ganglion cells receive visual information from a circular area of the visual field known as the receptive field.

Study reveals flexibility of neuronal processes underlying conscious perception

Our brains process many more stimuli than we become aware of. Often images enter our brain without being noticed: visual information is being processed, but does not reach consciousness, that is, we do not have an impression of it. Then, what is the difference between conscious and unconscious perception, and can both forms of perception be changed through practice?

Sanfilippo syndrome compromises blood-brain barrier, leads to brain damage

A study into the effects of Sanfilippo Syndrome type B (MPS III B) has found that the barrier responsible for protecting the brain from the entry of harmful blood-borne substances is structurally and functionally damaged by the devastating disease. University of South Florida researchers identified damage in specific brain structures involved in the pathology of MPS III B, one of four Sanfilippo syndromes, all of which are inherited diseases of metabolism.

Parkinson's disease medication turns on critical gene, protects brain cells

In a major breakthrough in the battle against Parkinson's disease, researchers at the University of Colorado School of Medicine have discovered a drug that stops the progression of the degenerative illness in mice and is now being tested in humans.
