BASAL GANGLIA
Indirect Pathway
, Indirect Pathway
1. Here are the main structures of
Motor Cortex the Indirect Pathway.
Striatum (Caudate & Putamen) X 2. Use the following slides to fill in
the type of connection (excitatory
*different subset of neurons or inhibitory) and neurotransmitter
used (glutamate or GABA) for each
step.
Globus Pallidus – externus (GPe ) X
3. Then explain how the indirect
pathway works to inhibit motor
Subthalamic nucleus X neurons and suppress motor
behavior.
4. Is the thalamus inhibited or
Globus Pallidus inturnus (GPi) X disinhibited as a result of activation
of this pathway
Thalamus
