Basolateral amygdala noradrenergic activity mediates corticosterone-induced enhancement of auditory fear conditioning.

abstract：:Whether or not spatial memories reorganize in the rodent brain is an unanswered question that carries the importance of whether the rodent provides a suitable animal model of human retrograde amnesia. The finding of equally impaired recent and remote spatial memory could reflect the continued importance of the hippoca...
