What happens in the brain when you become unconscious? What happens to our consciousness?

Unconsciousness is a complete reduction in consciousness, since it has a direct effect on the degree of wakefulness (vigilance).

The levels of wakefulness range from drowsiness to somnolence and sopor to unconsciousness anddifferent degrees of coma.

Drowsiness: Thinking and acting are clearly slowed down to apathy and the ability to orientate is reduced or limited; Low spontaneous linguistic expressions, slow thinking and reduced understanding.Easily awakenable by addressing or touching.

Somnolence: There is a constant drowsiness or propensity to sleep, which can be interrupted at any time by simple wake-up swells.No spontaneous linguistic statements; if so, then incomprehensible (murmurs). Reflexes are preserved. Decreased concentration and attention.

Sopor: Sleep-like condition from which sufferers can only be awakened with difficulty and application of strong stimuli, such as pain stimuli.No longer oriented, no linguistic expressions, reflexes received.

Coma: the highest degree of loss of consciousness when no one can be awakened by any means; neurologically, further degrees can be distinguished by increasing reflex failures up to the deepest coma, in which central life reflexes have extinguished and there is the greatest danger to life by suspending breathing.No defensive movements.

A special case of the coma is the so-called waking coma or apallic syndrome.The coma as an unregulated loss of consciousness must be distinguished from the drug-induced reduction of consciousness, which is called an artificial coma in medicine.

In emergency medicine, classification is common on the Glasgow Coma Scale (GCS).A reduction in consciousness can be recognized by the fact that the patient only slows down, does not react to (loud) response and touch at all. With advanced impaired consciousness, it also shows only untargeted defense or no reaction to pain stimuli.

Consciousness can occur after falling on the skull, diseases in the brain such as viral infection, encephalitis, herpes or stroke.

In the brain, a state is created that temporarily, at intervals or forever as a lower – non-essential function hides or switches off, as long as the organism as a whole develops a cure plan and tries to do so Implement.

In the context of unconsciousness, neither pain nor other feelings are perceived normally.One could compare this condition with a deep sleep, whereby dreams or mental ideas of those affected cannot be excluded.

With consciousness itself, nothing else happens so far.Either the patient gets it back after recovery or will never fully get it back and you remain in a coma or a wake-up coma. After a death, the whereabouts of our consciousness are still unclear. Was that helpful in the first place?
