BG major path
 Definition
parkinsons due to dn substnigra
-> dn direct and dn inhib fr indirect
Term
direct BG pathway
 Definition
cer cortex ex D1 in striatum
inh GPm, which nl inh VA/VL
VA/VL no longer inh so it excites motor cortex

SN also exc D1

indirect comes in by EXC GPm
Term
indirect BG pathway
 Definition
cer cortex ex D2 in striatum
inh GPl, no longer inh'ing subthal
subthal no can exc GPm
GPm doesn’t inhs VA/VL, so it GPm exc motor cortex

SN inh D2, so indirect pathway does NOT inh GPm
Term
parkinsons: indirect
 Definition
no inh of striatal D2 ->
inh of GPl ->
GPl doesn’t inh subthal ->
