Effects of meal size and proximal-distal segmentation on gastric activity

Figure 4 The power ratios showed the presence of both frequencies (1 cpm and 3 cpm) in the proximal and distal stomach, and that their intensities depend on the adopted proximal-distal segmentation and on the meal size ingested. ^aP < 0.03 between 60 and 180 mL for both frequencies in distal region, ^cP < 0.005 between ROIs 1 and ROIs 3, ^eP < 0.05 between ROIs 1 and ROIs 3, ^gP < 0.05 between ROIs 2 and ROIs 3. ROIs: Regions of interest.
