Topic: spatio-temporal receptive field (STRF)

Motion is encoded by the visual system using multiple cues. In primary visual cortex (V1), one cue is the tracking of object edges in a direction perpendicular to their orientation. Another cue, called motion streak, relates to tracking fast objects that create a smeared perception of motion along their trajectory. Intriguingly, dual tuning, to both cues in the same neuron, occurs in mutually perpendicular directions. We aimed to determine if dual tuning is predicted by a neuron’s spatio-temporal receptive field (STRF). Drifting white noise (DWN) patterns were presented at range of speeds (0:1
