Serotonin receptor: A rheostat in brain for emotion that may be linked to depression
Although drugs that target the brain's serotonin system are widely used to treat depression, the basic biological mechanism by which they help to alleviate symptoms is poorly understood. view more (2006-10-02)
Synchronous neuronal firing may underlie Parkinson's disease
In a finding that contradicts current theories behind Parkinson's disease, neuroscientists at Duke University Medical Center have discovered in mice that critical nerve cells fire all at the same time and thus overwhelm the brain's ability to control the body's movements. view more (2006-10-19)
Mayo researcher discovers target site for developing mosquito pesticides
A Mayo Clinic researcher has discovered a target site within malaria-carrying mosquitoes that could be used to develop pesticides that are toxic to the Anopheles gambiae mosquito and other mosquito species. view more (2006-12-21)
Drugs for Parkinson's disease may ease stroke-related disability
Scientists have untangled two similar disabilities that often afflict stroke patients, in the process revealing that one may be treatable with drugs for Parkinson's disease. view more (2007-04-04)
Research reveals why some smokers become addicted with their first cigarette
New research from The University of Western Ontario reveals how the brain processes the 'rewarding' and addictive properties of nicotine, providing a better understanding of why some people seemingly become hooked with their first smoke. view more (2008-08-06)
Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits. view more (2006-07-19)
Study Revises Dynamin's Role in Nerve Cell Function
An unexpected finding on how nerve cells signal to one another could rewrite the textbooks on neuroscience, says a collaborative team of researchers at Weill Cornell Medical College and Yale University. view more (2007-05-14)
Constant sunlight linked to summer suicide spike
Suicide rates in Greenland increase during the summer, peaking in June. Researchers writing in the open access journal BMC Psychiatry speculate that insomnia caused by incessant daylight may be to blame. view more (2009-05-08)
A new tool against brain disease
University of Utah researchers isolated an unusual nerve toxin in an ocean-dwelling snail, and say its ability to glom onto the brain's nicotine receptors may be useful for designing new drugs to treat a variety of psychiatric and brain diseases. view more (2006-08-21)
Throwing the micro switch: MicroRNA may link smoking risk gene to neurobiology of addiction
During the past several years, significant progress has been made in identifying susceptibility genes for nicotine dependence through genetic linkage and association analyses. view more (2009-04-23)
Research offers new approach to developing treatments for cocaine and amphetamine addiction
The study shows that highly addictive drugs, like cocaine and amphetamine, require a neurotransmitter called CART (Cocaine- and Amphetamine-Regulated Transcript) peptides to produce their maximal effects. view more (2005-09-29)
Genetic variant predicts antipsychotic response for schizophrenia patients by ethnicity
Schizophrenia is a developmental disorder with a large genetic component contributing to increased risk. Available antipsychotic medications treat some of the symptoms of schizophrenia, but are typically effective in only a subset of patients. view more (2008-01-09)
Medication eases obsessive-compulsive symptoms
A medication used to ease symptoms of amyotrophic lateral sclerosis, or Lou Gehrig's disease, also is helpful in treating people with treatment-resistant obsessive-compulsive disorder (OCD), according to a pilot study at Yale School of Medicine. view more (2005-08-01)
Researchers discover gene essencial to cerebellum formation
A study published this week in the scientific journal PNAS provides new information on the origin of different cells in the cerebellum, an important component of the central nervous system found in all vertebrates, including humans, and the part of the brain that controls movement. view more (2007-03-07)
Researchers find a key mechanism in the development of nerve cells
Chaos brews in the brains of newborns: the nerve cells are still bound only loosely to each other. view more (2009-09-30)
Mechanism of nicotine's learning effects explored
While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory—a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity disorder. view more (2007-04-05)
Why one way of learning is better than another
A new study from the Montreal Neurological Institute and Hospital (The Neuro) of McGill University reveals that different patterns of training and learning lead to different types of memory formation. view more (2009-10-02)
CSHL links activity in brain synapses and developmental abnormalities with schizophrenia gene
Cold Spring Harbor Laboratory (CSHL) researchers have identified a function of neuregulin1 (NRG1), a gene previously linked to schizophrenia but whose role in the disease was unknown. view more (2007-05-25)
Common treatment for methamphetamine overdose may damage brain cells
A common antipsychotic drug used in emergency rooms to treat methamphetamine overdose damages nerve cells in an area of the brain known to regulate movement, a new study shows. view more (2007-05-30)
Serotonin may play role in hardening of the arteries
A less active brain serotonin system is associated with early hardening of the arteries, according to a study presented today by University of Pittsburgh researchers at the 64th Annual Scientific Conference of the American Psychosomatic Society in Denver. view more (2006-03-06)
