WebAug 15, 2012 · The spike-field coherence was computed using an open-source Chronux library for MATLAB ( Bokil et al., 2010 ), a sliding window of 200 ms, and nine tapers. We measured the average coherence at low frequencies (1–30 Hz), gamma frequencies (30–200 Hz), and the low/gamma ratio. Webcxy = mscohere (x,y) finds the magnitude-squared coherence estimate, cxy , of the input signals, x and y. If x and y are both vectors, they must have the same length. If one of the signals is a matrix and the other is a vector, then the length of the vector must equal the number of rows in the matrix. The function expands the vector and returns ...
