  • Title: Dynamics of audio-visual interactions in the guinea pig brain: an electrophysiological study.
    Author: Demirtas S, Goksoy C.
    Journal: Neuroreport; 2003 Nov 14; 14(16):2061-5. PubMed ID: 14600498.
    Abstract:
    Audio-visual interactions and their specifications, evaluated by bioelectrical activities, in guinea pigs are presented in this study. The difference potential, as the evidence of an interaction, was calculated by subtracting the sum of averaged potentials recorded in visual and auditory events from the averaged potential recorded in an event where two stimuli combined in the same sweep. Dynamic investigations have shown an interaction when auditory stimulus is applied 24 ms before and 201 ms after visual stimulation. Latency between the difference potential and auditory stimulus was stable. Directional investigations have shown that the interaction is not observed when auditory and/or visual stimulation is used ipsilaterally, according to the recording side.
