Temporal characteristics of event-related BOLD response and visual-evoked potentials from checkerboard stimulation of human V1: a comparison between different control features.
This work is concerned with the temporal characteristics of event-related blood oxygenation level-dependent (ER-BOLD) and visual-evoked potential (VEP) signals produced by checkerboard stimulation of human V1. The study investigated whether different control features produce different amplitude VEPs, and if so, whether this corresponds to different ER-BOLD responses. The results showed that there was a difference in the amplitude of the P1-N1 components of the VEPs, and also in the magnitude and extent of the ER-BOLD responses. These results suggest the possibility that the P1-N1 components may be related to the difference in the magnitude and extent of the ER-BOLD response. Magn Reson Med 45:212-216, 2001.
