Which neurons are you considering? ‘you’ are the combined functions of billions of neurons spread across your brain.
When your next door neighbor wakes up in the morning, he’s (from your perspective) already waking up in another person’s body, and having their thoughts, personality, sexuality etc. That’s him, not you. You’re you because you have your body, thoughts, personality, sexuality etc. If you had his, you’d be him.
This is not a question of only biology, neurons are the basic structure of the organism, many functions are required to complete combination. Vegetative also have neurons, but has some damage on part of them, why he is unconscious?
