Neurophysiology of Learning Flashcards
1
Q
What is the basal ganglia architecture?
A
cortical (cortex)
sub-cortical (thalamus, striatum, Gpi/SNr, Gpe, Sub thalamus)
2
Q
What is the function of the striatum?
A
- Putamen (stimulus response/ habit formation)
- Caudate (action-outcome/ action selection)
- Nucleus accumbens (behavioural invigoration/motivation = pavlovian learning)
3
Q
What does caudate mean?
A
Action- Outcome
4
Q
What is putamen?
A
Stimulus-response/ Habitat formation
5
Q
Mechanics of learning-dopamine?
A
Releases after reward or removal of aversive stimulus
6
Q
Mechanics of learning?
A
sensory information - basal ganglia - motor cortex - action - reward
7
Q
Training implications on behaviour?
A
- hyper-motivation
- reduced action outcome, accelerated habit formation reduced flexibility once behaviours are learnt
