From vision to navigation and back
provides crucial guidance to navigation, and this guidance is a key function of the visual system. The communication between visual system and navigation system, however, appears to operate also in the opposite [...] environments and found modulation by spatial position in neurons throughout the visual cortex, including primary visual cortex (but not in its thalamic afferents). These navigational signals correlate [...] respond to vision only during navigation. Position signals, therefore, appear remarkably early in the visual system and permeate its operation. Various properties of these signals, including modulation by
