Phase-amplitude coupling in neuronal oscillator networks

Phase-amplitude coupling (PAC) describes the phenomenon where power of a high-frequency oscillation evolves with phase low-frequency one. We propose model that explains emergence PAC in two commonly-accepted architectures brain, namely, neural driven by an external input and interacting local oscillations distinct, locally-generated frequencies. further interconnection structure for brain regions demonstrate synchrony can integrate activities regulated control direction information flow across distant regions.
