SBU Study Shows Motor Cortex Could Have Larger Role in Parkinson's Disease |
The role of neuron and dopamine loss in Parkinson's Disease (PD) has long been recognized by neuroscientists. However, how dopaminergic modulation affects brain regions involved in the control of voluntary movement remains a subject of investigation. Researchers in the Department of Neurobiology and Behavior in the College of Arts and Sciences and the Renaissance School of Medicine at Stony Brook University, used an experimental model to demonstrate that a loss of midbrain dopaminergic centers impairs the ability of the primary motor cortex neurons to transform inputs into appropriate out...
