Abstract:
Objective:To study whether the orientation behavior of rats is affected by multi-sensory information.Methods: SD rats were randomly divided into 2 groups:the audio-visual integration group and pure audio group.The orientation behaviors of rats were observed after given single modal and multi-modal sensory cues with spatial disparities.Results:We found that when the temporal and spatial audio cues were coincident to a target visual cue,the rats had a markedly reduced reaction time and increased success rate in orientation behaviors;there was an obvious audio-visual integration effect.The integration effect was more obvious when the intensity of target visual cue was weak,with the enhancement efficiency being(87.3?8.5)%, significantly higher than that when the intensity of target visual cue was stronger(27.6%,P
