Parkinson S Disease Brain Areas Affected
People with parkinson s disease experience a loss of nerve cells in the part of their brains responsible for controlling voluntary movements.
Parkinson s disease brain areas affected. Is responsible for parts of motor control also has other functions. The subthalamic nucleus a nerve center near the substantia nigra.

When the neurons die or become impaired they produce less dopamine which causes the movement problems of parkinson s. The globus pallidus another nerve center responsible for movement balance and walking.
