Rats' processing of visual scenes: effects of lesions to fornix, anterior thalamus, mamillary nuclei or the retrohippocampal region.

Abstract:

We analysed the effects of lesions of hippocampal-diencephalic projections -- fornix (FX) mamillary bodies (MB) and anterior thalamic nuclei (AT) -- and retrohippocampal (RH) lesions including entorhinal cortex and ventral subiculum, upon scene processing. All lesions except FX were neurotoxic. Rats learned to discriminate among computer-generated visual displays ("scenes") each comprising three different shapes ("objects"). The paradigm was constant-negative; one constant scene (unrewarded) ...
