A nonlinear dynamics approach to assess amplitude-frequency coupling in non-invasive human electrogastrography recordings
Akshita A. Rao, Todd P. Coleman
Conventional electrogastrography (EGG) analyses summarize gastric slow-wave activity using dominant frequency, power, or phase-based metrics, without explicitly modeling amplitude-…
