A disease that produces decreased inhibitory input to the internal segment of the globus pallidus should have what effect on the motor area of the cerebral coex
The decrease in inhibition of globus pallidus internus will make its signals more strong.Globus pallidus internus inhibits thalamus. so inhibition of thalamus increases.Thalamus have an excitatory effect on motor coex, this signal is decreased as thalamus is inhibited.
Increased excitatory feedback directly to the coex
No effect
Decreased excitatory output from the thalamus to the coex
Increased excitatory output from the putamen to the coex
