3. Figure 2.
Sex-related differences in the response to the gut-directed stimulus. The response to the 45-mm Hg stimulus for the male and female subjects (compared with baseline) is shown. The left column shows voxels of significantly greater activation (P < 0.05) in female patients, and the right column shows voxels with significantly greater activation in male patients (shown in radiologic orientation).
