The Body Senses and Movement
The Body Senses
primary motor cortex
supplementary motor area
Sent via the thalamus.
Basal ganglia smooth movements by
facilitating outputs to thalamus
inhibiting outputs to the thalamus
Especially active during complex movement sequences
Involved in learning about motor sequences
Damage to Basal Ganglia results in inability to stop/start movement
Inability to learn motor sequences
Two major pathways:
direct and indirect pathways
have opposite net effects on their thalamic target structures:
