Week 10 Group 1 Amanda Ayoub Kindra Akridge Barbara Kim Alyona Koneva. The Role of the Basal Ganglia in Habit Formation. Explain the difference between a goal directed action and a habit, and provide a couple of your own examples of each.

3. Show us the Basal Ganglia, and discuss neurotransmitters and their functions …The following diagrams show 2 coronal slices that have been superimposed to include the involved basal ganglia structures.
Inhibitory GABA-containing projection neurons
Dopaminergic pathway leads to GABAergic (dis-inhibitory) direct pathway
3. Show us…The main components of the basal ganglia are the striatum, which consist of the caudate nucleus and the putamen, and the globus pallidus.
6. It seems like the basal ganglia do two things, one involving steps using inhibition and (tonic) excitation to cause actions to happen, and one that inhibits actions.
Instrumental behavior occurs whenever an outcome is contingent on a response.
Instrumental behaviors differs from reflexes and fixed action patterns, which are not controlled by the contingency between behavior and its consequences.
Lesions to the basal ganglia (particularly the striatum) disrupt “instrumentality” of actions. Animals that were tested could no longer perform or acquire actions in order to earn specific rewards or avoid aversive stimuli.
