A “twisted” visual field map in the primate cortex predicted by topographic continuity

Abstract

Adjacent neurons in sensory cortex have overlapping receptive fields within and across area boundaries. In early visual cortex this creates areas with mirror or non-mirror representations of the visual field, an arrangement which is theorized to minimize wiring cost. We demonstrate that a more complex map consisting of both types of representation exists in an extrastriate area, and show how this can emerge from a mechanism that maintains topographic continuity.
