Question 6

function of basal nuclear function?

Answer 6

`decision to move

Answer 8

neostriatum (striatum)

• caudate nucleus*
• putamen*
• nucleus accumbens

palleostriatum (pallidum)
-globus pallidus**

• input

simultaneously inhibits the execution of competing motor programs

Answer 24

indirect pathway for the basal nuclei
