PS267 Lecture Notes - Lecture 19: Explanatory Gap, Complex System, Brainstem
Document Summary
Lecture 19 consciousness: the mind-brain problem, the anatomy of consciousness, levels of arousal and consciousness, the organization of complex systems, nonconscious processing, the contents of consciousness, split-brain research and consciousness. Dualism = brain and mind are separate entities. Materialism = the brain and mind are both physical entities. The explanatory gap = the gap between dualism and materialism. The having of perceptions, thoughts, and feelings. To have awareness of the external world. Whether sentient experiences are the same across different individuals.

Locked-in syndrome unable to move any muscles but is fully conscious. Sleepwalking may perform complex motor sequences while asleep: suprachiasmatic nucleus (scn): controller of our circadian pacemaker, arousal regulation:
