Loops

Question 1

Motor Loop

Answer 1

Afferent from motor and sensory areas of the brain to the putamen then the the thalamus. The thalamus then projects back to the motor cortex giving the coordinated movement

Question 2

Cognitive/Association Loop

Answer 2

Afferents from various corical areas reach the caudate nucleus and nucleus succumbant which contains dopaminergic connections (providing reward affirming feelings), then projections reach the thalamus and then back to the cortical areas

Question 3

Limbic Circuit

Answer 3

hippocamus, amygdala, and the limbic lobe all project to the caudate nucleus, which fires dopaminergic projections, sending signals to the thalamus (of what behaviors to promote or inhibit), the thalamus projects back to the limbic areas of the cortex
