Abstract

Visual event-related potentials (ERPs), especially early components (N170, P170) were recorded from nine scalp electrodes by using three-dimensional (3D) and two-dimensional (2D) stimuli to evaluate the differences between 3D stimuli and 2D stimuli on each component. At occipitotemporal sites, the N170 latencies for 3D stimuli were significantly longer and the N170 amplitudes for 3D were significantly larger than those of 2D stimuli. These findings may suggest that 3D stimuli may activate brain differently from 2D stimuli.
