FIG 3. Functional MR data obtained while patient was asleep.

A, Activation patterns observed during the sleeping study show activation in the expressive (top) and receptive (bottom) language areas.

B, Pixel intensity and time courses correlated with the reference function. Note the difference in responses between the expressive (top) and receptive (bottom) areas during the first three blocks. This finding suggests a regionally different response to the auditory stimulus.
