Figure 1. Schematic of brain circuits activated by visceral and central nervous system-directed stimuli. Gray highlighted areas indicate brain regions showing greater activation in (A) male patients and (B) female patients. Gastroenterology 2003 124, 1738-1747DOI: (10.1016/S0016-5085(03)00400-1)
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).
