Document Summary
Sleep is stable, therefore is an altered state. The thalamus is like a gateway, in the centre of the brain. Information gets sent along nerve cells, through the spinal cord and to the thalamus. You process that information and you get a response which goes back down the same way it came up. For seeing, it goes through your eyes to the occipital lobe (back of brain) Prefrontal lobes: involved in cybernetic control functions if the brain. In some stages of sleep, certain parts light up and some don"t - this effects your dreams. Dreams occur in the occipital lobe (where you actually see things) Nerve cells: do the information processing in the brain. Recently found that glial cells and astrocytes do a lot of the processing (support cells) There"s a gap (very tiny) between cells called a synapse. The change in the electrical potential gets released in the gap, these chemicals are called neurotransmitters.
