Comparison of power for random firing versus correlated firing. A, High-gamma power of a randomly firing population of 105 neurons with model exponent (n in Eq. 2) set to 2 (red trace) as the firing rate increases from 10 to 100 spikes/s, superimposed with the high-gamma power of the same population of neurons firing with a correlation coefficient that increases from 0 to 0.00045 (with firing rate fixed at 10 spikes/s). B, Correlation coefficient required to match the high-gamma power of a randomly firing population with a firing rate of 100 spikes/s, for different values of N (size of the neural population) and model exponent.
