Using a novel system, researchers found that a part of the basal ganglia called the striatum is not involved in action selection as previously thought. Instead, the striatum and the motor cortex work ...

University of Arizona researchers have revealed new insights into the neurobiological cause of the involuntary, uncontrollable movement disorders that develop in patients with Parkinson’s disease (PD) ...

You stub your toe on the bedpost. Before your brain even registers the pain, a word explodes from your mouth—sharp, loud and ...

Neurons deep in the brain not only help to initiate movement-they also actively suppress it, and with astonishing precision. This is the conclusion of a new study by researchers at the University of ...

SNr neurons in the midbrain send precise signals to control movement. Their activity determines which movements actions are initiated or inhibited. Neurons deep in the brain not only help to initiate ...

Scientists have studied the main source of serotonin in the brain -- the dorsal raphe nucleus (DRN). By studying how activating the brain's 'serotonin center' affects awake animals for the first time, ...
