Direct evidence for encoding of motion streaks in human visual cortex

Apthorp, Deborah; Schwarzkopf, D. Samuel; Kaul, Christian; Bahrami, Bahador; Alais, David; Rees, Geraint

Description

Temporal integration in the visual system causes fast-moving objects to generate static, oriented traces ('motion streaks'), which could be used to help judge direction of motion. While human psychophysics and single-unit studies in non-human primates are consistent with this hypothesis, direct neural evidence from the human cortex is still lacking. First, we provide psychophysical evidence that faster and slower motions are processed by distinct neural mechanisms: faster motion raised human...[Show more]
