I think this is more of a Neurophysics question and I am just asking a question with no experience in this field. I know the consciousness works because the neurons can send electrical signals within the brain. If I assume the right and left brain is apart from each other and the right brain is sending a signal to the left brain. From where the brain is apart from each other and the electrical signal cannot pass to the other side of the brain I would create a new electrical signal to match the signal on the other side of the brain even though it is apart from each other. I know electrical signal travels at the speed of light. If someone has an identical brain to mine and his right or left brain has the same signal matching my brain then technically our brain can function as one. If I have an arm long enough to circle the earth three and a half time and I touch the ground, I should be able to feel my hand touching the ground one second after because light travels the earth three and a half times in one second. The problem is if I have a one second delay in between the traveling electrical signal between my right brain and my left brain then the consciousness might not work out. The same reason I do not feel other person's consciousness because his mind has electrical signal traveling with a different timing. My question is, how long of a delay can I have between the traveling electrical signal between my right brain and my left brain and I would still have my consciousness?
