Mean spectral probability distributions for each extracted feature (beta–gamma, theta-1, and theta-2). In a the distributions are plotted by condition to highlight the differences in each feature; whereas in b the distributions are plotted by feature. In each plot, frequency in Hz is represented along the abscissa and the mean probability is plotted along the ordinate
