From: Multi-timescale phase-amplitude couplings in transitions of anesthetic-induced unconsciousness
Phase-amplitude plots for 15 PAC couplings at 18 checkpoints for Group A, who received a mixture of ketamine and alfentanil. The amplitude of high-frequency IMF is shown in different colors; Y-axis represents the phase of low-frequency IMF. Each sub-figure profiles the phase-amplitude plots covering 18 checkpoints for each PAC coupling.
