Abstract

Nervous systems adapt to the prevailing sensory environment, and the consequences of this adaptation can be observed both in the responses of single neurons and in perception. Given the variety of time-scales underlying events in the natural world, determining the temporal characteristics of adaptation is important to understanding how perception adjusts to its sensory environment. Previous work has shown that neural adaptation can occur on a timescale of milliseconds, but perceptual adaptation has typically been studied over relatively long timescales, typically on the order of seconds. This disparity raises important questions: Can perceptual adaptation be observed at brief, functionally relevant timescales? And if so, how do its properties relate to the rapid adaptation seen in cortical neurons? We address these questions in the context of visual motion processing, a perceptual modality characterized by rapid temporal dynamics. We demonstrate objectively that 25 ms of motion adaptation is sufficient to...
