Research may bring new generation of cochlear implants

A Rutgers University team led by neuroscientist Robin Davis is opening new doors to improved hearing for the congenitally or profoundly deaf.

Depletion of antioxidant glutathione linked to Parkinson's in mice

Scientists at the Buck Institute have shown that mice suffering from a depletion of the antioxidant glutathione in dopamine-producing neurons developed nerve damage and symptoms associated with Parkinson's disease (PD) in humans.

Overexcited neurons not good for cell health

Neurotransmitters have consequences. They initiate events that are critical to a healthy life, giving us the ability to move, to talk, to breathe, to think. But that's if the neurotransmitters are getting it right and sending proper signals downstream to muscle cells, neurons or other cells.

Brain malfunction explains dehydration in elderly

As Australia faces another hot, dry summer, scientists from Melbourne's Howard Florey Institute have warned that elderly people are at risk of becoming dehydrated because their brains underestimate how much water they need to drink to rehydrate.

Dynamic connectivity rewires neuronal circuits on the fly to sharpen senses

Researchers from the Center for the Neural Basis of Cognition (CNBC), a joint project of Carnegie Mellon University and the University of Pittsburgh, have for the first time described a mechanism called "dynamic connectivity," in which neuronal circuits are rewired “on the fly” allowing stimuli to be more keenly sensed.

Aging gracefully requires taking out the trash

Suppressing a cellular cleanup-mechanism known as autophagy can accelerate the accumulation of protein aggregates that leads to neural degeneration.

Immune system may target some brain synapses

A baby's brain has a lot of work to do, growing more neurons and connections.

Green tea for Parkinson's disease

Does the consumption of green tea, widely touted to have beneficial effects on health, also protect brain cells? Authors of a new study being published in the December 15th issue of Biological Psychiatry share new data that indicates this may be the case.

Early treatment stops epilepsy in its tracks

Yale School of Medicine researchers have shown for the first time that it is possible to suppress the development of epilepsy in genetically predisposed animals - which could open the door to treating epilepsy as a preventable disease.

Nematodes provide clues to dopamine's role in human aging diseases

Research carried out with a paintbrush bristle, a metronome, smelly chemicals and thousands of microscopic worms called nematodes may reveal important information about human aging diseases like Parkinson's and Alzheimer's, thanks to a grant from the Ellison Medical Foundation awarded to a University at Buffalo neurobiologist.

Biodegradable polymers with neurotransmitters promote nerve regrowth

Research reported December 11 in the journal Advanced Materials describes a potentially promising strategy for encouraging the regeneration of damaged central nervous system cells known as neurons.

Effects of space radiation on astronauts

Cold Spring Harbor Laboratory (CSHL) scientists recently led a team of researchers to study potential effects of space radiation on astronauts. The results of their study are revealing and will provide the foundation for ensuring the safety of crew members participating in long distance space travel.

New model for neurodegeneration

The gradual loss of dopamine neurons is a hallmark of many neurodegenerative diseases - Parkinson's Disease chief among them.

New studies on brain and behavior from the world's leading scientists

The 2007 American College of Neuropsychopharmacology Annual Meeting will feature hundreds of new studies on brain and behavior from the world's leading scientists.

Polybrominated diphenyl ethers used as fire retardants could be harmful

Polybrominated diphenyl ethers (PBDEs), chemicals used as fire retardants, can be found in numerous items in the home, such as the television, computer, toaster and the sofa.

Nicotine has significant effects on brain GABA

There is a clear link between GABA - a chemical substance of the central nervous system that inhibits neurons in the brain - and nicotine dependence, according to a study presented at the American College of Neuropsychopharmacology (ACNP) annual meeting.

Genetic animal model of autism

By introducing a gene mutation in mice, investigators have created what they believe to be the first accurate model of autism not associated with a broader neuropsychiatric syndrome, according to research presented at the American College of Neuropsychopharmacology annual meeting.

Stable sleep patterns and regular routines may improve outcomes in bipolar disorder

Bipolar disorder, commonly known as manic-depressive disorder, is highly influenced by the circadian system - the body's internal clock - and a specific kind of psychotherapy may help decrease irregularities in the circadian system that can trigger key symptoms of bipolar disorder, according to a study presented at the American College of Neuropsychopharmacology (ACNP) annual meeting.

New understanding of biological effects of alcohol on genes within cells

Alcohol triggers the activation of a variety of genes that can influence the health and activity of brain cells, and new research from Weill Cornell Medical College in New York City sheds light on how that process occurs.

Neurons in the frontal lobe may be responsible for rational decision-making

You study the menu at a restaurant and decide to order the steak rather than the salmon. But when the waiter tells you about the lobster special, you decide lobster trumps steak. Without reconsidering the salmon, you place your order - all because of a trait called "transitivity."
