• Parkinson's disease damages to the motor pathway

  Changes in the Motor Pathways: The Parkinson disease is a neurological disorder that is in the brain that occurs in the basal ganglia. This disease is a degenerative disorder in the central nervous systems.

• Deteriorating brain structure affects behavior

  Thus, the nigra cells are unable to form synapses through which they secrete and relay dopamine to the striatum in a neural circuit within the basal ganglia.

• The Cerebral Cortex and the Motor Cortex

  The signal to move is given by the basal ganglia which has a role in initiation of movement. When the basal ganglia signals, the primary motor cortex becomes active in sending down the signals to control the muscles. 2.

• Brain Structure

  The basal ganglia is a complex system of nuclei that also controls motor functions. The basal ganglia have a major role in cognitive functions. Both the cerebellum and the basal ganglia play major roles in sensorimotor functions.

• Cerebellum: Regulation of Motor Control

  The apex of the motor hierarchy is the cerebral cortex, in particular the primary motor cortex, the lateral premotor area, and the supplementary motor area. Motor activity is also modified by the cerebellum and basal ganglia.

• Parkinson Disease:brain structure, neurotransmitter involved

  The motor cortex is the structure that actually initiates and controls movement. It receives input from the basal ganglia via the thalamus, as well as from many other areas of the brain.

• Brain structures and their functions

  Hello again, Basal ganglia: The basil ganglia is responsible for voluntary motor control, procedural learning relating to routine behaviors or "habits" such as eye movements, cognitive and emotional functions, helps us decide which behaviors to execute

• The Four Major Nuclei of the Basal Ganglia

  Basal Ganglia The basal ganglia are comprised of three major structures and many other smaller nuclei, collectively referred to as the basal forebrain (which will be discussed later).

• Motivation and Brain Function

  The research suggests that higher-fit children exhibited larger volumes in specific sub regions of the basal ganglia, which may impact task performance.
