Document Summary
Primary difference between classical and instrumental conditioning is that in instrumental conditioning the individual"s response determines the outcome vs classical conditioning the cs and. Ucs occur at certain times regardless of individual"s behaviour. Engram: physical representation of what has been learned. Said if learning depends on new/strengthened connections between 2 brain areas, a knife cut somewhere in brain should interrupt that connection and abolish learned response. Proved learning and memory do not rely on a single cortical area. Equipotentiality: all parts of cortex contribute equally to complex behaviours and any part can substitute for any other. Mass action: the cortex works as a whole and more cortex is better. Richard thompson identified one nucleus of cerebellum; the lateral interpositus nucleus lip as essential for learning. Supressing red nucleus temporarily prevents responses to learning but does not prevent learning. Cerebellum critical for many other instances of classical conditioning but only if delay between cs.
