Sleep attacks from Parkinson`s drugs do exist
Car crashes in patients with Parkinson’s disease have been associated with sudden sleep attacks caused by dopamine drugs, but the concept of sleep attacks, and their connection with dopamine drugs, has been disputed.   view more (2002-06-19)

Flies on speed offer insight into the roles of dopamine in sleep and arousal
Methamphetamine, the drug of choice for long-distance truckers and college students pulling all-nighters, appears to do a similar trick for fruit flies, too. This finding is one of several in a new study that demonstrates a critical role for the neurotransmitter dopamine in the modulation of sleep,... view more (2005-07-12)

Dopamine study sheds new light on drug addiction
A paper published in today's issue of Science has challenged beliefs about the role of dopamine in the brain, which could lead to new treatments for Parkinson's disease, schizophrenia and drug addiction. The research suggests that dopamine has a far wider, less specialised role than previously... view more (2005-03-02)

New finding in studying dopamine transporter
Confirming findings in a previous study, Yale researchers observed an altered availability of the dopamine transporter in healthy persons with a genetic variation linked to substance abuse and attention deficit hyperactivity disorder (ADHD).   view more (2005-06-07)

1 sleepless night increases dopamine in the human brain
Just one night without sleep can increase the amount of the chemical dopamine in the human brain, according to new imaging research in the August 20 issue of The Journal of Neuroscience.   view more (2008-08-20)

Study suggests loss of 2 types of neurons -- not just 1 -- triggers Parkinson's symptoms
New evidence indicates that the loss of two types of brain cells--not just one as previously thought--may trigger the onset of symptoms associated with Parkinson's disease.   view more (2007-08-14)

Insulin signaling and amphetamines
Abuse of psychostimulants such as amphetamine remains a serious public health concern. Amphetamines mediate their behavioral effects by stimulating dopaminergic signaling throughout reward circuits of the brain.   view more (2007-10-16)

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)

New findings show additional similarity between opiate and nicotine addiction
"That was good!" "Do it again." This is what the brain says when people use tobacco, as well as 'hard drugs' such as heroin.   view more (2008-02-13)

Depression linked to previously unknown dopamine regulator
Researchers from Harvard Medical School have found a molecule that is unexpectedly involved in dopamine signaling, and in a manner that supports the potential of dopamine as an alternative target for treating depression.   view more (2005-07-29)

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... view more (2006-10-16)

Spookiness is in the brain of the beholder
EMBARGOED UNTIL WEDNESDAY 24 JULY 2001 19:00 BST UK CONTACT - Claire Bowles, New Scientist Press Office, London: Tel: +44(0)20 7331 2751 or email claire.bowles@rbi.co.uk WHETHER or not you believe in the paranormal may depend entirely on your brain chemistry. People with high levels of dopamine... view more (2002-07-24)

Given Up on the New Year's Resolution?
New research reveals why smokers find it so difficult to quit Despite widespread knowledge of the harmful effects of cigarette smoking, nearly 30% of the population still smoke. It can be extremely difficult to stop and fewer than 20% are successful, even with the use of nicotine replacement. The... view more (2003-01-31)

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)

Gene therapy reduces cocaine use in rats
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have shown that increasing the brain level of receptors for dopamine, a pleasure-related chemical, can reduce use of cocaine by 75 percent in rats trained to self-administer it.   view more (2008-04-16)

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... 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)

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)

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... view more (2004-03-05)
