Medial Temporal Lobe Structures Contribute to on -Line Processing

Results described in preceding chapters reinforce and extend the emerging view that structures of the medial temporal lobe contribute to the on-line processing of visual stimuli. These experiments uniquely demonstrate that the MTL is necessary for normal apprehension of even single stimuli when degraded, and for normal discrimination of even very simple representations after a brief delay. Changes were observed in a maintained representation over time in the face of interference, but only in the presence of MTL lesions. Explanation of these findings requires a theory of substantial scope that can explain why information cannot be easily integrated over time. One candidate is an extension of relational memory theory, which previously has addressed primarily enduring representations. However, an inability to bind together even simultaneously available information might manifest in the fashion reported here. Theoretical contributions of other authors are also considered, but the available data do not permit definitive adjudication between the alternatives. Even so, my results and those of others clearly indicate that MTL structures are active participants in the representation of visual stimuli.
