Figure 6. Visual ERPs.

Figure 6

Visual ERPs elicited by the appearance of the explosion-shaped figure are shown for the H-SLI, TD, and adult groups over a representative set of electrodes. All ERPs are difference waves that were created by subtracting auditory only trials from AV stimuli with different offsets in order to reveal brain activity specific to visual stimulation. Difference waves are labeled based on the subtraction that was used to create them. For example, the AV500-A panel shows visual ERPs that were revealed by subtracting auditory only trials from ERPs elicited by audiovisual stimuli with a 500 ms offset. Measured components are marked on the O2 site. Negative is plotted up.
