 Partibational complexity analysis uses brief pulses to measure the electrical activity of the brain, which can be used to determine if a person has consciousness. This technique was tested on both volunteers and patients, as well as mice, to examine the underlying neural circuits involved in consciousness. During wakefulness, stimulation of deeper layers of the cortex produces a brief pulse of excitation, followed by a biphasic sequence of 120 melisocons of profound off-period and a rebound excitation. In thalamic nuclei, this same pattern is observed, but it is less pronounced due to burst spiking. Running or anesthetizing the mouse reduces the cortical and thalamic off-period and rebound excitation, and eliminates the late component in the EEG. These results suggest that corticothalamo cortical interactions drive the long-lasting evoked EEG signals elicited by deep cortical stimulation during the awake state.
