LEARNING ABOUT S-S RELATIONS

NEUROBIOLOGICAL MECHANISMS

Pavlovian conditioning in Aplysia

Pairing specific enhanced sensitization

CS allows Ca++ to enter, which fosters the conversion of ATP to cAMP by adenylate cyclase

Cerebellum and the conditioned eyeblink (Thompson)

Advantages of the eyeblink paradigm

Methods: Lesion, activation, record activity

Neural systems

US pathway (from trigeminal n.)

CS pathway (from auditory n.)

Convergence (interpositus n.)

Inhibition of inferior olive and blocking

Amygdala and emotion

Role in fear (Fanselow, LeDoux)

Neural systems

US pathways

CS pathways
