Putamen Loop
-cortices send info to ? Putamen using GLU & ACh
-putamen x SNpr & GPi using GABA -SNpr & GPi x output by thalamus using GABA so thalamus is NOT x & fires which excites/? the motor cortices to fire using GLU
-so ultimately, Putamen Loop ? motor activity
Caudate - Oculomotor Loop
-cortices send ? to caudate nucleus using GLU & ACh
-caudate x GPi & SNpr using GABA
-GPi & SNpr is x = thalamus not x = thalamus fires
-thalamus activated=? of Frontal Eye Fields & Supplementary Eye Fields (using GLU) = eye movement
-therefore, oculomoto
indirect pathway
-GPe x STN using GABA - striatum x GPe using GABA
-if GPe is not x then the STN is not x so it will fire. which will then activate ? of GPi & SNpr (using GLU) which then x the thalamus. if thalamus is x it no longer ? the cortices for movement. therefore,
