    abstract = {Evidence is reviewed indicating that striate cortex in the monkey is the source of two multisynaptic corticocortical pathways. One courses ventrally, interconnecting the striate, prestriate, and inferior temporal areas, and enables the visual identification of objects. The other runs dorsally, interconnecting the striate, prestriate, and inferior parietal areas, and allows instead the visual location of objects. How the information carried in these two separate pathways is reintegrated has become an important question for future research.},

Mishkin et al. proposed a theory suggesting that visual processing runs in two pathways: the what' and thewhere' pathway.

The `what' pathway runs ventrally from the striate and prestriate to the inferior temporal cortex. This pathway is supposed to deal with the identification of objects.

The `where' pathway runs dorsally from striate and prestriate to inferior parietal pathway. This pathway is supposed to deal with the localization of objects.

Mishkin et al. already recognized the question of how and where the information carried in the different pathways could be integrated. They speculated that some of the targets of projections from the pathways, eg. in the limbic or system or the frontal lobe, could be convergence sites. Mishkin et al. stated that some preliminary results suggest that the hippocampal formation might play an important role.
