Cortico-cortical dynamics and learning during visual recognition: a computational model

A ubiquitous feature of the neocortex is the reciprocity of connections between its many distinct areas: if area A projects to area B, then area B almost invariably projects to area A [5, 22]. While the role of the feedforward projections in facilitating tasks such as visual recognition is generally well-acknowledged, the precise computational role of the corresponding feedback projections has remained relatively unclear (cf. [1] p. 23).
