  • These ranges provided the limits around each animal’s target values for fitting ensemble models. Phase and duty cycle are displayed in normalized units. Metrics of slow wave height and spike height were used to ensure models were physiologic and were estimated from recordings. Target ranges are compared to mean and SD of the measurements across six animals for HE(8) and HE(12) in the columns to the right for peristaltic (peri) and synchronous (sync) coordination modes. Motor phase progression is calculated using phase of both motor neurons, so it was displayed only once under HE(8).
