Study: cannabis a double-edged sword
A new neurobiological study has found that a synthetic form of THC, the active ingredient in cannabis, is an effective anti-depressant at low doses. However, at higher doses, the effect reverses itself and can actually worsen depression and other psychiatric conditions like psychosis. view more (2007-10-24)
Dissecting the machinery of nicotine's reward
Understanding what makes people crave the high of nicotine is a key to developing treatment for this highly addictive drug. And that understanding involves tracing the neural machinery by which nicotine switches on the brain's reward machinery. view more (2006-06-15)
Research study describes the role part of the brain plays in memory
A research with experimental rats carried out by the Institute of Neuroscience of the UAB describes the brain region connected to how our declarative memory functions. view more (2007-07-18)
Brain's cannabinoid system 'mellows' seizures
The same brain machinery that responds to the active substance in marijuana provides a central "on-demand" protection against seizures, researchers have found. They said their discoveries suggest that the "endocannabinoid" system might constitute a prime target for drugs against seizures of epilepsy and other neurodegenerative... view more... (2006-08-17)
Study links chemical to inhibited milk synthesis, secretion in humans
University of Cincinnati (UC) researchers have identified the neurotransmitter serotonin as the chemical responsible for inhibiting milk production and secretion in human mammary glands. view more (2007-10-09)
Brain works more chaotically than previously thought
The brain appears to process information more chaotically than has long been assumed. This is demonstrated by a new study conducted by scientists at the University of Bonn. view more (2007-02-28)
New Target Found to Fight, Treat Parkinson's
Neuroscientists from the University at Buffalo have described for the first time how rotenone, an environmental toxin linked specifically to Parkinson's disease, selectively destroys the neurons that produce dopamine, the neurotransmitter critical to body movement and muscle control. view more (2005-08-25)
Hepatic encephalopathy and prehepatic portal hypertension rat model
A research article to be published June 21, 2009 in the World Journal of Gastroenterology addresses this question. The research team lead by Dr. Gabriela Beatriz Acosta, observed that the activity of GS was increased in the hippocampus in PH rats. view more (2009-06-29)
Researcher finds new use for botox
Botox, used by Hollywood stars to smooth out facial wrinkles, is playing an important role in UQ research to understand how nerve cells communicate with each other. view more (2005-09-22)
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 induced plasticity and maintaining active networks... view more...

Defects in crucial brain protein implicated in memory loss
The ability to recognize familiar objects and companions is lost when levels of a protein crucial for recycling a chemical messenger in the brain are reduced, mimicking some of the symptoms of Alzheimer's disease. view more (2006-09-07)
Miniature implanted devices could treat epilepsy, glaucoma
Purdue University researchers have developed new miniature devices designed to be implanted in the brain to predict and prevent epileptic seizures and a nanotech sensor for implantation in the eye to treat glaucoma. view more (2007-08-08)
PET imaging confirms link between receptor levels and cocaine abuse
Using positron emission tomography (PET), researchers have established a firm connection between a particular brain chemistry trait and the tendency of an individual to abuse cocaine and possibly become addicted, suggesting potential treatment options. view more (2006-07-12)
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)
Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. view more (2006-03-06)
Alcoholism-associated molecular adaptations in brain neurocognitive circuits
After many years of heavy drinking, alcohol produces pathological alterations in the brain. In many alcoholics these changes culminate in massive social deterioration and disorders of memory and learning. view more (2008-07-09)
Are Anxiety Disorders All in the Mind?
Using single-photon emission computed tomography (SPECT), researchers in The Netherlands were able to detect biochemical differences in the brains of individuals with generalized social anxiety disorder (also known as social phobia), providing evidence of a long-suspected biological cause for the dysfunction. view more (2008-05-13)
UCLA Find Yields Further Insight Into Causes of Parkinson's Disease
In humans, a dearth of the neurotransmitter dopamine has long been known to play a role in Parkinson's disease. It is also known that mutations in a protein called parkin cause a form of Parkinson's that is inherited. view more (2007-02-02)
Bodybuilders abusing prescription-only drugs bought on the internet
Bodybuilders who abuse prescription-only drugs bought on the internet are risking their health, highlights a case report in the British Journal of Sports Medicine. The easy availability of these drugs from this source is a cause for concern, conclude the authors. view more (2002-02-01)
Popular antidepressant associated with a dramatic increase in suicidal thoughts amongst men
Nortriptyline has been found to cause a ten-fold increase in suicidal thoughts in men when compared to its competitor escitalopram. These findings are published in the open access journal BMC Medicine. view more (2009-10-15)
