The visual system can deter-mine motion and depth from ambiguous information contained in images projected onto both retinas over space and time. The key to the way the system overcomes such ambiguity lies in dependency among multiple cues-such as spatial displacement over time, binocular disparity, and interocular time delay-which might be established based on prior knowledge or experience, and stored in spatiotemporal response characteristics of neurons at an early cortical stage. We conducted a psychophysical investigation of whether a single ambiguous cue (specifically, interocular time delay) permits depth discrimination and motion perception. Data from this investigation are consistent with the predictions derived from the response profiles of VI neurons, which show interdependency in their responses to each cue, indicating that spatial and temporal information is jointly encoded in early vision.
