Basal ganglia

 

Basal ganglia became highly developed in birds where it took over the control of motor functions, being the most vast control  in this organisms. In man it is subjugated by the higher cortex so that it takes over the function of subconscious, emotional and psychological functions. It also controls instinct and instinctual learning.

Differences between cerebellar and basal ganglia disease

This mainly by distinguishing the type of tremor. While in cerebellar disease, we have intention tremor, in basal ganglia disease, (parkinsonism) we have tremor at rest.

Both cerebellum and basal ganglia mediate the function of the extrapyramidal system.  In Parkinson's disease (basal ganglia) we expect to find the following

  • Increase muscle tone

  • Cogwheel rigidity

  • Tremor at rest

  • We also have symptoms like hemiballism, full ballism, athetosis, ataxia and chorea.
