Abstract or Description

One of the most fundamental questions in cognitive neuroscience is to understand how the brain constructs our three-dimensional visual world from two-dimensional retinal signals of light and dark intensity. At the time this paper was written, the seminal work of Sperry and his colleagues studying patients who had undergone sections of the corpus callosum was most influential (Gazzaniga et al 1962; Sperry et al 1969).

They reported that visual object recognition up to the level of functional significance or meaning was intact in the disconnected right hemisphere, merely the verbal label could not be retrieved. Consequently, at that time current theorising tended to conflate perceptual processing and semantic processing to a single post-sensory categorical stage such that object recognition was achieved by a single system (eg Sutherland 1968, 1973; Tenenbaum and Barrow 1976).
