How Does the Brain Work: Hypothesis

 Everybody knows how the heart works, if you ask anyone they will tell you something like, "well it pumps blood all over the body", but then:

how does the brain work?

     Before any research on this, my guess of how does the brain control everything is by electrochemical signals/impulses. The brain uses impulses to signal what to do. these electric impulses are what it makes us do everything; open our eyes, get out of bed, etc. we move our muscles because we tell our brain to send these electric impulses to our muscles through efferent pathways, these are passed through the spinal chord and sent to the desired muscle by efferent neurons all the way until the movement happens, this is a very fast process. the Brain and spinal chord is the CNS (Central Nervous System) and everything else is PNS (Peripheral Nervous System)
