Functional Anatomy of Wakefulness

The wakefulness (W) phase of the SWC in humans usually happens during the day. Only during W are we aware of ourselves and our environment; that is, only during W do we feel, think, and work in full knowledge of what we do and fully use our senses and faculties. During W is when we properly process all the information that reaches the thalamus and the cerebral cortex from the sensory organs and from the propioceptors and intraceptors distributed in our organism. W is therefore necessary for our nervous system to support the organization of cognitive processes in their different categories. The state of W primes the nervous system to perform these functions.
