Humans lose consciousness when the oxygen supply to the brain gets low.
Hypoxia is a condition where the brain does not receive enough oxygen. It can lead to symptoms such as confusion, dizziness, and in severe cases, loss of consciousness, brain damage, or death. Prompt medical attention is necessary to address hypoxia and prevent complications.
There are two main types of consciousness: phenomenal consciousness, which relates to our subjective experiences and perceptions, and access consciousness, which involves the processing and integration of information in the brain that allows us to be aware of our surroundings and make decisions. Other types, such as self-consciousness and higher-order consciousness, are also proposed by some theories of consciousness.
Loss of consciousness is most likely with damage to alerting areas of the brain in the midbrain and brain stem. While the cortex is implicated in conscious processes, it is a large and redundant structure. Loss of cortex is more likely to result in a deficit of specific functions such as speech comprehension or production then complete loss of consciousness.
The consciousness system is a wide spread yet organized system of neurons located in the brainstem, diencephalon, and cerebral hemispheres. It also includes the reticular formation, hypothalamus, basal forebrain, and thalamus.
Consciousness is controlled by the cerebrum of our brain.
No single part of the brain is responsible for consciousness. The brainstem, diencephalon, and cerebral hemispheres are all involved in consciousness.
Some unanswered questions about consciousness include: What is the exact nature of consciousness? How does consciousness arise from the brain's neural activity? Can consciousness exist independently of the physical brain?

Consciousness is a complex phenomenon and is not localized to one specific area of the brain. It is believed to involve widespread neural activity and interactions across various regions of the brain, including the prefrontal cortex, parietal cortex, and thalamus. The exact mechanisms of consciousness and its neural correlates are still not fully understood.
Syncope is a brief loss of consciousness due to lack of oxygen.SyncopeSyncope - Temporary loss of consciousness caused by a lack of blood supply to the brain.
