Research links 'ecstasy' to survival of key movement-related cells in brain
New research from the University of Cincinnati (UC) suggests that the widely abused club drug "ecstasy," or MDMA, can increase the survival of dopamine cells in the brain during fetal development. view more (2006-10-19)
Ritalin packs punch by elevating norepinephrine, suppressing nerve signal transmissions
Methylphenidate (Ritalin) elevates norepinephrine levels in the brains of rats to help focus attention while suppressing nerve signal transmissions in the sensory pathways to make it easier to block out extraneous stimuli, a Philadelphia research team has found. view more (2006-05-30)
Study reveals how ADHD drugs work in brain
Although millions depend on medications such as Ritalin to quell symptoms of attention deficit hyperactivity disorder (ADHD), scientists have struggled to pinpoint how the drugs work in the brain. view more (2006-06-26)
Study may explain why exercise helps heart failure patients
Aerobic training is associated with a reversal of abnormal hormonal patterns that underlie many of the debilitating symptoms of heart failure. view more (2006-04-28)
Cocaine's effects on brain metabolism may contribute to abuse
Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's "reward" chemical once its signal is sent. view more (2008-02-19)
Scientists provide new evidence for cellular cause of SIDS
University of Chicago researchers and colleagues have found strong support that a disturbance of a specific neurochemical can lead to sudden infant death syndrome, the primary cause of death before age 1 in the United States. view more (2006-03-08)
What emotional memories are made of
Both extensive psychological research and personal experiences confirm that events that happen during heightened states of emotion such as fear, anger and joy are far more memorable than less dramatic occurrences. view more (2007-10-05)
Alcoholism, smoking and genetics among Plains American Indians
Alcoholism and smoking have a high rate of co-occurrence in the general population. Yet little is known about the co-morbidity of alcoholism and smoking among American Indians. view more (2006-02-23)
Univ. of Chicago scientists find potential cause of breathing problems in Rett Syndrome children
A multi-institutional team, led by University of Chicago researchers, has taken a crucial step toward understanding and treating Rett syndrome (RS), a rare and often-misdiagnosed neurodevelopmental disorder that affects 1 in 10,000 children, mostly females. view more (2005-12-14)
St. John's Wort relieves bladder pain in animal models
St. John's Wort, an herbal supplement used for centuries, may be effective in relieving pain that occurs in hypersensitive bladder disorders such as interstitial cystitis (IC), according to animal model study results presented today at the annual meeting of the American Urological Association. view more (2006-05-24)
Jefferson Researchers Find Potential Biomarker for Heart Failure
Signs of heart failure may be in the blood. Cardiac researchers at Jefferson Medical College have found an enzyme in the blood that could be a potential marker for heart failure. view more (2005-08-22)
Study shows new strategy for developing antidepressants
Researchers may be able to develop an antidepressant which takes effect almost immediately by directly targeting novel molecules in the brain instead of taking a less direct route, which can lead to longer times for medication to take effect, according to a new study presented at the American College of Neuropsychopharmacology (ACNP) annual... view more...

Bacteria, beware: New finding about E coli could block infections, lead to better treatments
A newly discovered receptor in a strain of Escherichia coli can be blocked to avert infection, a finding that might aid in developing better therapies to treat bacterial infections resulting in food poisoning, diarrhea or plague. view more (2006-06-27)
Pular antidepressants boost brain growth, Hopkins scientists report
The beneficial effects of a widely used class of antidepressants might be the result of increased nerve-fiber growth in key parts of the brain, according to a Johns Hopkins study being published in the January 2006 issue of the Journal of Neurochemistry. view more (2005-12-20)
UGA study finds that regular exercise plays a consistent and significant role in reducing fatigue, increasing energy
Forget so-called energy drinks. A new analysis by University of Georgia researchers finds overwhelming evidence that regular exercise plays a significant role in increasing energy levels and reducing fatigue. view more (2006-11-02)
Sunlight and serotonin underlie seasonal mood disorders
Authors of a research letter in this week's issue of THE LANCET provide further evidence that the effect of sunlight on neurotransmitters in the brain plays a significant role in seasonal mood disorders. The success of phototherapy (ultraviolet light therapy to stimulate brain neurotransmitter activity) and drugs that prevent the reuptake of the... view more... (2002-11-29)
Drug cuts sleep apnea in heart failure patients
Since sleep apnea is associated with heart failure, patients who take a single dose of acetazolamide-a mild diuretic and respiratory stimulant-before going to bed exhibit less sleep apnea, improved blood oxygen levels and fewer daytime symptoms of sleepiness. view more (2006-01-16)
Protein Plays Critical Role in Heart Failure in Both the Heart and Adrenal Gland
A protein that plays an important regulatory role in heart failure in the heart also exerts powerful effects on the adrenal gland, Jefferson Medical College researchers have found. view more (2005-11-16)
New protein synthesis not essential to memory formation
New research from the University of Illinois challenges the premise that the brain must build new proteins in response to an experience for that experience to be recorded in long-term memory. view more (2007-07-27)
Common PTSD drug is no more effective than placebo
Guanfacine, a medication commonly prescribed to alleviate symptoms of post-traumatic stress disorder, is no more effective than a placebo, according to a study led by researchers at the San Francisco VA Medical Center. view more (2006-12-04)
