Latent inhibition (LI) refers to the retardation in learning about the significance of a neutral stimulus that results from its nonreinforced preexposure. There is evidence that electrolytic or aspiration lesions of the hippocampal formation can disrupt LI (see I. Weiner, 1990). It has been suggested that this effect may stem from the interruption of a projection from the retrohippocampal region to the nucleus accumbens (A. J. M. Clark et al., 1992). The present experiment assessed this… CONTINUE READING
