Abstract:
Macaque area V4 neurons are generally not selective for direction of motion, as judged from their response to directional stimuli presented after a baseline condition devoid of movement (classical paradigm). We used a motion-adaptation paradigm to investigate whether stimulation history influences direction-of-motion selectivity. We found that classically non-directional V4 neurons develop direction-of-motion selectivity after adaptation. This underscores the dynamic nature of functional cortical architecture.
