Summary of simulated gastric model parameters compared to published values that have been determined experimentally

Source [14] [15] [16] [17] Model
Species Hound dogs Mongrel dogs Human Mongrel dogs Human
Frequency (cpm) 4-6 1.58-1.88 2.68-3.28 N/A 3
Duration (s) N/A 6.8-8.5 N/A Submucosal cells: 4.4-5.6 7.9
Myenteric cells: 6.1-6.5
Propagation N/A Circular muscle: Corpus: 2.2 Circular muscle Antrum:
velocity (mm/s) 16.6-19.2 Antrum: 6.8 (fibre): 15.5-29.9 LM: 16.9
Circular muscle CM1: 12.5
(cross fibre): 5.8-16.6 CM2: 10.7

Note the results from Horiguchi et al[16] are indirect measurements while the other sources are direct tissue measurements and results from Xu et al[15] correspond to isolated tissue strips. In the model results, LM is the outer longitudinal muscle layer, CM1 is the middle circular muscle layer and CM2 is the inner circular muscle layer.
