The K-complex is a major graphoelement of sleep EEG. This report demonstrates that K-complexes emerge from a cortically generated slow (<1-Hz) oscillation. Human EEG as well as cat cellular and field potential recordings converge into demonstrating that the K-complex results from a synchronized cortical network that imposes periodic excitatory and inhibitory actions on cortical neurons. We additionally show the correspondence between neuronal activities and the shape of the K-complex. Spectral… CONTINUE READING
