midbrain cross section with staining

Midbrian with no immunhistochemistry

Inputs to the caudate and putamen
Teh caudate and putamen receive inputs from the cortex and substantia nigra (midbrain)

Outputs from basal ganglia

Describe the basis of GABAergic signalling
The basis of control is GABAergic inhibitory signalling. The GABAergic circuit design means that output is the result of an inhibition of an inhibition: disinhibition.

Describe a suimple Basal ganglia circuit

Disinhibitory cicuits

DIretc pathway of reinforement in basal ganglia

Indirect pathway of inhibition of basal ganglia

Direct vs indirect pathway

hyperdiretc pathway of basal ganglia

Motor and non motor loops in brain

Parkinson histopathology
Lewy Bodies - an accumulation of -synuclein protein

Parkinson disease patho
Get lack of coordinated movements as loose control.
