ABSTRACT
Figure 3. Visual and Auditory Event-Related Hemodynamic Responses (A) Visual evoked hemodynamic responses following the presentation of faces for a subgroup of six subjects. Activations in right primary visual cortex are shown overlaid on an axial slice of the template MRI used for spatial normalization. On the left, the fitted response and adjusted data are plotted as a function of peri-stimulus time for the most significant voxel in right primary visual cortex for two subjects. Activations are thresholded at p < 0.05 (corrected). (8) Auditory evoked hemodynamic responses due to the presentation of an unpleasant 1 kHz tone for a subgroup of six subjects. Activation of primary auditory cortices are overlaid on the normalization template. On the left, the fitted response and adjusted data are plotted as a function of peri-stimulus time for the most significant voxel in the left primary auditory cortex for two subjects. Activations are thresholded at p < 0.05 (corrected).
