Corrected imaginary phase-locking value (ciPLV)

Source: R/coupling-frontier.R
ciPLV.Rd

ciPLV (Bruna et al. 2018) corrects the imaginary part of the PLV for the size of its real part, giving a phase-synchrony estimate that is robust to zero-lag (volume-conduction) coupling.

Usage

ciPLV(
  x,
  y = NULL,
  sr = NULL,
  freq_band,
  order = 4L,
  modality_x = NULL,
  modality_y = NULL,
  channels_x = 1L,
  channels_y = 1L
)

Arguments

x, y

Signals (or a single object from which a pair is extracted).

sr

Sampling rate in Hz.

freq_band

Numeric c(low, high) band in Hz.

order

Butterworth filter order for the band-pass (default 4).

modality_x, modality_y, channels_x, channels_y

Passed to the internal signal-pair extractor.

Value

A single ciPLV magnitude in [0, 1].
