Hippocampus is critical for contextual learning 

Crucial for explicitly learning about the CS-US contingency and contextual learning.

In conditioning procedures, training occurs in a situational context (e.g., cage training, testing room). If threat conditioning occurs in a particular context, trainee can associate that context with the aversive US. Contextual cues alone can evoke CRs (typically weak); strongest CRs when CS + contextual cues are present. Contextual effects found to be reduced/absent if the hippocampus is damaged/removed. Implies a hippocampal input ot he amygdalae.

Cortex is responsible for feelings

Feelings of fear are elicited by a CS following training (if person is awear of CS). Feelings require cortical regions beyond the hippocampus and sensory cortices (removal doesn’t eliminate feelings). Many different cortial areas are associated with emotional experiences- some of these are connected with the amygdalae and/or sensory cortical areas....
