Moving objects are a problem for the human visual system because as their images move across the retina, they stimulate disparate neurons across cortex. Holcombe and his collaborators investigate how signals from different neurons' glimpses of a moving object areas are combined, as well as how temporal limits constrain tracking of important objects in a dynamic scene.

Holcombe also studies temporal aspects of the processing of stationary objects. Behavioral experiments, illustrated by the animations here, compare speed limits for different features and the dynamics of how these features are bound into a coherent percept.

Ongoing applications include assessing whether brain-damaged patients' temporal deficits are improved by magnetic brain stimulation, and testing the effect of naps on temporal processing.
