Sep 24, 2022 · Phase amplitude coupling (PAC) is thought to play a fundamental role in the dynamic coordination of brain circuits and systems.
This measure is based on the phase-slope index (PSI) between the phase of slower oscillations and the power envelope of faster oscillations. Further, we propose ...

The authors introduce a novel method of measuring directed connectivity by applying the framework of Granger causality to phase shift events.
We present a new measure for assessing phase-amplitude CFC. This measure is defined as an adaptation of the Kullback–Leibler distance.
