We are referring to phenomenal consciousness - the subjective experience of being aware. This type of consciousness involves the first-person perspective of experiencing sensations like seeing or hearing.
The primary auditory cortex, located in the temporal lobe, is the first cortical area to receive auditory information from the thalamus. It is responsible for processing and analyzing basic auditory signals.
The journey towards that which already is (enlightenment) begins by choosing a meditation technique and starting your practice. For example, you could choose to do Vipassana (watching the breath) for five or ten minutes a day. At first, you will become more aware of your thoughts, feelings, and physical sensations. Over time, your consciousness will deepen, and you may become aware of more subtle phenomena. When the moment is right, the dewdrop that is your individual "I" (the ego) will disappear into the ocean of cosmic consciousness. WU!
You would not find cell bodies of neurons in the cerebral cortex. Instead, the cerebral cortex mainly contains the axons, dendrites, and synapses of neurons, as well as glial cells that provide support and function.
Auditory nerves are first relayed to the thalamus on the way to the temporal lobes auditory cortex. The thalamus is the gray matter between the cerebral hemispheres.

He had slept heavily while the dark pressed at his window, but as the first pink tips of dawn began to tap agains the glass, consciousness seemed to seep into him like a noxious gas.
To widen our state of consciousness, we must first understand the meaning of consciousness. We must experience moments of it, of mindfulness or mindlessness. When we stop the mind from its rattling, from its constant thinking, and experience being the witness, being the observer, this is consciousness. First consciousness may appear for a moment, or a few moments, then you can widen your consciousness by spending more and more time being conscious, observing the mind, controlling the mind from wandering from thought to thought. Therefore while the term widen your state of consciousness may be misleading, one can increase their level of consciousness slowly and steadily by the realization of the Truth. By yearning for liberation and unification, one can be a yogi who lives in union with the Divine, in a state of consciousness of the truth which is full of bliss and peace.
The part of the cerebral cortex that matures first is the part that controls physical movement.
Visual information first passes through the thalamus in the brain before traveling to the visual cortex. The thalamus acts as a relay station that helps to route sensory information to the appropriate areas in the cortex for further processing.
The primary auditory cortex, i.e. where the auditory signal first reach the cortex, is located on the Heshl's gyrus, on the supratemporal plane (the upper part of the temporal lobe). The auditory information then spreads to secondary auditory cortices located around primary the primary auditory cortex. Then the auditory signal diffuses to associative areas located in the parietal and frontal lobes.
Technically, it supplies both at the same time, however, you could argue that the common carotid artieries (the main vessels supplying your head) reach the medulla first. Mainly because the whole cortex takes longer to be vascularized, however, we are probably talking milliseconds here. Also, the medulla receives blood vessels from the vertebral arteries, which are a branch of the subclavian artery, which is a more direct root. Hope this helps!
