But there's a lot that were we're still uncoveringnd,

we're not even sure how to sort out and classify all the different neurons in the brain either. And what doyou evin by electrical and chemical communication, you know, it's i think we sort of understand that when we talk about a computer and ones and zeros and some combination of ones and zeros means something. How does s that work? Do we even understand how that works in the brain? I

would say the short answer is no. The long answer is that we have lots of theories, and i think we have parts of the answer. For examplea most narrow scientists subscribe to the idea that information is encoted in basy, how fast the brain cells are firing. So it's not one and zeros in the sense of a binary code, but it's more of what they call a rate code, so that these more active nerons are in coting their activity based on the number of times that they are sending that signal. But it's much more an that. And one of the things thats differenc between the kind of ones and zeros picture that we have of the way conpuror work, is that the communication might be encloted in the rates, basically the number ofa spi that you get, or voltage pulses that you get from one of these neurons. But at the same time, its dumping out chemicals, and those chemicals kind of spread out, kind of throughout the brain. And so in addition to that rapid communication that we have in the brain, we have these slow, active forms of communication. These nemodulators affect your mental state though. As you feel awake and alert, afraid, tired, bored, whatever it is, those of these slow acting changes tou even though the signals might be the same, your mental state has changed because of the chemical that are going on in the background, ebbing and flowing slowly throughout your day.
