The work consists of the analysis of the visual cortex and its relation to behaviour, and of the changes in mnemonic function following circumscribed cerebral lesions and stimulation in the monkey. The work is concerned with establishing the nature of the residual capacity and of trying to determine whether the basis for the acuity results lies within the retinal grain or in the non-independence of units within the visual pathways. The work suggests that the residual capacity is simply the integral of the types of responses found from retinal ganglion cells. Memory changes were analyzed in terms of a distinction between short-term and long-term processes. Results tentatively suggest that frontal cortical lesions or stimulation, might be characterized as producing an alteration in retrieval from the short-term store, this in turn being produced by an alteration in stimulus sampling. Temporal lobe lesions appear to affect transfer from short-term to long-term store, without affecting the capacity of either store. Current work is directed towards finding the critical structures, if any, in the temporal lobes and also in thalamic regions. Author
