Perceptual fields reveal previously hidden dynamics of human visual motion sensitivity.

Motion sensitivity is a fundamental property of human vision. Although its neural correlates are normally only directly accessible with neurophysiological approaches, Neri (Neri P. J Neurosci 34: 8449-8491, 2014) proposed psychophysical reverse correlation to derive perceptual fields, revealing previously unseen dynamics of human motion detection. In this Neuro Forum, these key findings are discussed, putting them into broader context and pointing out possible implications of spatial scale considerations on the interpretation of the findings and dynamic model proposed.
