New genetic model for Parkinson's disease
Researchers at the Karolinska Institute in Sweden are homing in on mechanisms that may explain one set of causes for Parkinson's disease. view more (2006-07-28)
Who knew he was the alpha male?
How do you know if a stranger will be nice or nasty? Professor Cliff Summers' group at the University of South Dakota has found that you can predict the social status of male lizards before they fight. What is more, green Anolis lizards show their fighting fitness through a colour signal on their face. Wayne Korzan has discovered that how fast... view more... (2004-03-25)
Exercise may lead to improvement in patients with Parkinson's
A new study from researchers at the Keck School of Medicine of the University of Southern California (USC) shows that treadmill exercises may benefit patients with Parkinson's Disease and those with similar movement disorders. view more (2007-05-16)
Insight into dopamine role suggests new treatment pathway for Parkinson's
Dopamine (DA) not only functions as a neurotransmitter, a chemical messenger between neurons by which one neuron triggers another, researchers have found. view more (2006-10-19)
Obesity predisposition traced to the brain's reward system
The tendency toward obesity is directly related to the brain system that is involved in food reward and addictive behaviors, according to a new study. view more (2008-07-30)
Addiction: Insights from Parkinson's disease
A new comprehensive review by researchers at the Montreal Neurological Institute (MNI), McGill University and the University of Cambridge, England provides vital insights into the neurological basis of addiction by investigating Parkinson's disease patients, who in some instances develop various addictions when undergoing medical treatment. view more (2009-02-26)
UCI researchers find new way to fight cocaine addiction
UC Irvine pharmacological researchers have discovered that blocking a hormone related to hunger regulation can limit cocaine cravings. view more (2009-04-02)
Identification of dopamine 'mother cells' could lead to future Parkinson's treatments
'Mother cells' which produce the neurons affected by Parkinson's disease have been identified by scientists, according to new research published in the journal Glia. view more (2008-04-08)
Study of the drug, Isradipine, to determine if it slows or prevents Parkinson's disease
Gloria E. Meredith, Ph.D., collaborated with D. James Surmeier, Ph.D. and other scientists at Northwestern University to study the drug, Isradipine, and its possible effects on Parkinson's disease. view more (2007-06-14)
U of M researchers identify process that may help treat Parkinson's, spinal cord injuries
A new discovery by University of Minnesota researchers may lead to a better understanding of how the spinal cord controls how people walk. These insights could help lead to treatments for central nervous system maladies such as Parkinson's disease and spinal cord injuries. view more (2008-04-17)
Research supports toxoplasmosis link to schizophrenia
Scientists have discovered how the toxoplasmosis parasite may trigger the development of schizophrenia and other bipolar disorders. view more (2009-03-11)
Neural stem cells reduce Parkinson's symptoms in monkeys
Primates with severe Parkinson's disease were able to walk, move, and eat better, and had diminished tremors after being injected with human neural stem cells. view more (2007-06-13)
Brain model enhances understanding of schizophrenia
A new model for the interaction among the nerve cells of the cerebral cortex may be a step on the way to improving treatment for schizophrenia and ADHD. The model, which describes the function of three types of inhibitory nerve cells in the frontal lobe, is being presented in the scientific journal PNAS by researchers from Linköping... view more...

New evidence on addiction to medicines Diazepam has effect on nerve cells in the brain reward system
Addictions to medicines and drugs are thought to develop over a relatively long period of time. The process involves both structural and functional changes in brain nerve cells that are still poorly understood. view more (2008-08-28)
Gene controlling circadian rhythms linked to drug addiction, UT Southwestern researchers find
The gene that regulates the body's main biological clocks also may play a pivotal role in drug addiction, researchers at UT Southwestern Medical Center have found. view more (2005-06-14)
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)
A Novel Mechanism of Manganese-Induced Neurological Dysfunction Discovered
For decades, scientists have known that chronic exposure to high concentrations of the metal manganese can cause movement abnormalities resembling symptoms of Parkinson's disease, but apparently without the same neuron damage characteristic of Parkinson's patients. view more (2006-08-29)
Food restriction increases dopamine receptor levels in obese rats
A brain-imaging study of genetically obese rats conducted at the U.S. Department of Energy's Brookhaven National Laboratory provides more evidence that dopamine - a brain chemical associated with reward, pleasure, movement, and motivation - plays a role in obesity. view more (2007-10-25)
Immune cells contribute to the development of Parkinson's disease
Parkinson disease is a neurodegenerative disorder that impairs movement, balance, speech, and other functions. It is characterized by the loss of nerves in the brain that produce a substance known as dopamine. view more (2008-12-23)
Researchers reveal how the brain processes important information
Researchers at UT Southwestern Medical Center have shed light on how the neurotransmitter dopamine helps brain cells process important information. view more (2009-04-03)
