Cortical arousal and automatic arousal

Webcortical: [adjective] of, relating to, or consisting of cortex. WebDuring NREM sleep, joint changes in ECA and autonomic activity may be orchestrated by joint activations of (cortical) arousal and autonomic arousal promoting regions in the brain stem26 (“brain 27 stem activation”), whose substrates partially overlap [15]. This may, for example, be in response to an arousing stimulus, either
