结局指标
主要结局
Phase amplitude coupling (PAC) strength
时间窗: up to 2 weeks
Gut-brain connectivity will be assessed using phase-amplitude coupling (PAC) to examine the interaction between gastric electrical oscillations and cortical rhythms. PAC will be calculated from electrophysiological raw data to produce one unitless value ranging from -1 to 1, for each subject. The higher the value, the greater the gut-brain connectivity/PAC strength.
