Image Credit: Photos.com New brain research suggests lazy people could be naturally born that way. Published in the Journal of Neuroscience, the study was performed by a team of scientists from Vanderbilt University who found evidence which suggests a person´s willingness to work hard and make money are tied to specific chemicals in 3 areas of the brain. The scientists also say these new studies could improve the treatment and research of Attention-Deficit Disorder, Depression...

Discovery has implications for neurodegenerative and psychiatric disorders Scientists at the Gladstone Institutes have determined how specific circuitry in the brain controls not only body movement but also motivation and learning, providing new insight into neurodegenerative disorders such as Parkinson's disease–and psychiatric disorders such as addiction and depression. Previously, researchers in the laboratory of Gladstone Investigator Anatol Kreitzer, PhD, discovered how an...

An agent under consideration for use in PET imaging combats neuronal death to relieve Parkinsonian symptoms in animal models, according to a study published on April 2nd in the Journal of Experimental Medicine. The movement-related symptoms of Parkinson's disease, including muscle rigidity and tremors, are caused by the loss of dopamine-secreting neurons in the brain. Current therapies aim at increasing and maintaining dopamine levels to correct these motor impairments. However, these...

A study from Karolinska Institutet shows that a new drug for Huntington's disease - pridopidine or dopamine stabilizer ACR16 - might operate via previously unknown mechanisms of action. Researchers have found that at very low concentrations, ACR16 binds to the sigma-1 receptor, a protein in the brain important to neuronal function and survival. This new knowledge can be used to develop future treatments for schizophrenia, involuntary Parkinsonian tremors and neurodegenerative diseases....

Patients studied produced pictures, sculptures, novels and poetry Some Parkinson's Disease patients can suddenly become creative when they take dopamine therapy, producing pictures, sculptures, novels and poetry. But their new-found interests can become so overwhelming that they ignore other aspects of their everyday life, such as daily chores and social activities, according to research published in the March issue of the European Journal of Neurology. Italian researchers studied 36...

Mark Twain said, "Giving up smoking is the easiest thing in the world. I know because I've done it thousands of times." Many smokers would agree that it's difficult to stay away from cigarettes. A new study in Biological Psychiatry this month now suggests that low dopamine levels that occur as a result of withdrawal from smoking actually promote the relapse to smoking. Dopamine is a brain chemical messenger that is critically important in reward and motivation. Some research suggests that...

Researchers have found a way to study how our brains assess the behavior — and likely future actions — of others during competitive social interactions. Their study, described in a paper in the Proceedings of the National Academy of Sciences, is the first to use a computational approach to tease out differing patterns of brain activity during these interactions, the researchers report. “When players compete against each other in a game, they try to make a mental model of...

New research shows how neurons interact and could lead to new treatment for addiction Harvard scientists have developed the fullest picture yet of how neurons in the brain interact to reinforce behaviors ranging from learning to drug use, a finding that might open the door to possible breakthroughs in the treatment of addiction. The finding is the result of a year-long effort by a team of researchers led by associate professor of Molecular and Cellular Biology Naoshige Uchida to examine...

A brain cell type found where habits are formed and movement is controlled has receptors that work like computer processors to translate regular activities into habits, researchers report. "Habits, for better or worse, basically define who we are," said Dr. Joe Z. Tsien, Co-Director of the Brain & Behavior Discovery Institute at Georgia Health Sciences University. Habits also provide mental freedom and flexibility by enabling many activities to be on autopilot while the brain focuses...

Researchers convert astrocytes directly into dopamine-producing nerve cells of the midbrain In efforts to find new treatments for Parkinson´s Disease (PD), researchers from the Perelman School of Medicine at the University of Pennsylvania have directly reprogrammed astrocytes, the most plentiful cell type in the central nervous system, into dopamine-producing neurons. PD is marked by the degeneration of dopaminergic neurons in the midbrain. Dopamine is a brain chemical important in...
