Taste memory trace disruption by AP5 administration in basolateral amygdala

N-methyl-D-aspartate receptor has been related to learning and memory processes. Its characteristics make it a key candidate in the modulation of associative processes at physiological level. Traditionally, the main efforts have been directed to show its role in excitatory conditioning. Nevertheless, the studies that have analyzed its implication in inhibitory learning are scarce. We present an experiment where a preexposure effect on the conditioning (latent inhibition) is disrupted by 2-amino-5-phosphonopentanoic acid administered in basolateral amygdala. This data shows interference on taste memory trace, and attenuation of the inhibition effect.
