PL inactivation during conditioning disrupted acquisition of the contextual bi-conditional discrimination. Rates of responding are represented as mean suppression ratios (±SEM) for CS presentations. Rats receiving saline infusions during conditioning exhibited greater levels of suppression to the CS paired with shock in that context, relative to the CS presented without shock in that context. Rats receiving muscimol infusions into the PL cortex during conditioning failed to exhibit context selective responding towards the CSs.
