Alpha-power is moderately, yet systematically, inversely correlated to the mean firing rate (black) of the cortical node. B. The LFP time series show spontaneous fluctuations within the alpha-band. Low-amplitude alpha-oscillatory modes are accompanied by higher frequency activity. C. The MUA of the cortical node shows rhythmic bursting associated with an increase in alpha-band power (values shown for CSF = 0.6).
