Evidence suggests that “consciousness” is the mechanism that allows separate parts of the brain to communicate with other parts of the brain and coordinate activities. The hypothesis is this is done by the frontal cortex which is responsible for reasoning, decision making, and controlling voluntary movements. However, there is still much research required in Neurosciences before we have a solid theory and understanding of consciousness.

So in other words… it exists.

It is worth nothing that the first sentence is exactly my perspective, as I explicitly stated earlier:

I think that consciousness in the brain is just an approach that it uses to aggregate and share information amongst several subcomponents.
