Research reveals molecular basis of neural circuits
26. July 2010 06:47
The basal ganglia is a series
of highly connected
brain areas localised deep in the cerebral cortex that recently has attracted interest of neuroscientists when it was linked to learning, and discovered to be affected in a number of disorders of the addictive and obsessive spectrum, but also in
Parkinson's disease (PD). And now researchers think they have understood why as they found that neurons in this area signal the beginning and the end of voluntary
actions
