In the processing of negative memory, which parts of the amygdala receive input from the cerebral cortex?

central nucleus (abbreviated CEA for some reason)
The basolateral and lateral nuclei project to the ____________ for positive conditioning (rewards) and ____________ for negative conditioning (punishments).
