Parkinson's disease is a degenerative disorder of the central nervous system that is characterized by tremors, rigidity, slowness of movement, and difficulty walking. It is caused by loss of the neurons that produce the neurotransmitter dopamine (known as dopaminergic neurons). One of the primary goals in Parkinson's disease research is to develop a replacement for dopaminergic neurons. In this issue of the Journal of Clinical Investigation, researchers led by Takuya Hayashi at the RIKEN...

Last year a clinical trial of L-DOPA -- a mainstay of Parkinson's disease therapy -- was launched for Angelman syndrome, a rare intellectual disorder that shares similar motor symptoms such as tremors and difficulty with balance. The clinical trial is based on a 10-year-old case report showing benefit with the drug, but few studies since have explored the neurological justification for using L-DOPA to treat parkinsonian features in Angelman syndrome. New research from the University of...

redOrbit Staff & Wire Reports — Your Universe Online Some drugs used to treat ADHD could affect the brain's reward system, researchers from the University of Copenhagen have discovered. The findings make it easier to understand how the medicine works and could ultimately lead to improvements in the development of and the dose determination associated with ADHD treatments, they report in the latest edition of the Journal of Neurophysiology. As part of the study, Jakob Kisbye...

Scientists may have discovered why the standard treatment for Parkinson's disease is often effective for only a limited period of time. Their research could lead to a better understanding of many brain disorders, from drug addiction to depression, that share certain signaling molecules involved in modulating brain activity. A team led by Bernardo Sabatini, Takeda Professor of Neurobiology at Harvard Medical School, used mouse models to study dopamine neurons in the striatum, a region of...

Dopamine Has Many Messages
2012-07-18 14:59:38

In the insect brain, dopamine-releasing nerve cells are crucial to the formation of both punished and rewarded memories Children quickly learn to avoid negative situations and seek positive ones. But humans are not the only species capable of remembering positive and negative events; even the small brain of a fruit fly has this capacity. Dopamine-containing nerve cells connected with the mushroom body of the fly brain play a role here. Scientists from the Max Planck Institute of...

Study shows people who have lower levels of the brain chemical are more likely to be aggressive when provoked in competitive situations Out of control competitive aggression could be a result of a lagging neurotransmitter called dopamine, say researchers presenting a study at the Society of Nuclear Medicine's 2012 Annual Meeting. During a computer game against a putative cheating adversary, participants who had a lower capacity to synthesize this neurotransmitter in the brain were more...
