Retinal direction of motion is reliably transmitted to visual cortex through highly selective thalamocortical connections.

ABSTRACT: Motion perception is crucial to animal survival and effective environmental interactions. In mammals, detection of movement begins in the retina. Directionally selective (DS) retinal ganglion cells were first discovered in the rabbit eye,¹ and they have since been found in mouse,^2,3 cat,⁴ and monkey.^5,6 These DS retinal neurons contact a small population of neurons in the visual thalamus (dorsal lateral geniculate nucleus [LGN]) that are highly DS.^7,8,9,10 The primary visual cortex (V1) also contains DS neurons, but whether directional selectivity in V1 emerges de novo^11,12,13
