  • Title: Lack of a temporal gradient of retrograde amnesia following NMDA-induced lesions of the basolateral amygdala assessed with the fear-potentiated startle paradigm.
    Author: Lee Y, Walker D, Davis M.
    Journal: Behav Neurosci; 1996 Aug; 110(4):836-9. PubMed ID: 8864274.
    Abstract:
    M. Kim and M. Davis (1993b) previously reported that electrolytic lesions of the central nucleus of the amygdala, made 6 or 30 days after training, completely blocked the expression of fear-potentiated startle in rats. The present study shows that excitotoxic lesions of the basolateral amygdala also block fear-potentiated startle and do so whether the lesions are made soon (i.e., 6 days) or long (i.e., 30 days) after training. The relevance of these findings to various theories of amygdala function is discussed.
