Abstract

For a person to be conscious the main factor, condition and proof is the state of being awake. While the biological phenomenon of neuro circuit process is kept entirely functional at all times, the consciousness anatomic structures operate under different conditions as it is proved by many MRI scan and EEG supervision. Thalamus is an important key; it remains arousal and relays sensory, motor, and critical cortical circuits. Hypothalamic area and basal forebrain is involved in wake and sleep-promoting system. The ”Awake state” correlates with an abnormality in the midbrain, pons, thalamus, or cortex.
