Document Summary
There are no cures for these, but medication is getting better and better. Schizophrenia: dopamine is overactive: we need to calm down the dopamine. How neurons work: neurons are the cells that communicate information; they do this through the membrane (like all cells) and the membrane has channels in it, these channels open up for various reasons. You can electrically or chemically stimulate them to open up: when they are open, there is a high proportion of sodium on the outside of the cell. Whenever it happens, the cell is said to have fired: the fire ignites the next and heats until it reaches the end of the axon which is the nerve terminal. The information flows from the end of one axon to the dendrite of the next. The contact point between the nerve terminal on the axon and the dendrite is called the synapse.
