Who at one time or another has not compared an idea to an electrical spark or spoken of the "chemistry" of a particular mood? The brain does indeed convey its signals by means of electricity and chemical compounds; so much is well known. But the finer details of how it actually manages these transmissions, and at prodigious speeds—sometimes firing several hundred nerve impulses in a second—still make for fascinating inquiry. The scientific understanding of electricity in the nervous system has come a long way since the s, when Luigi Galvani of Bologna noticed that disembodied frog legs hanging on copper hooks from an iron balcony would occasionally twitch, as if still animated.

These target cells may be in glands, muscles, or other neurons. Billions of neurotransmitter molecules work constantly to keep our brains functioning, managing everything from our breathing to our heartbeat to our learning and concentration levels. They can also affect a variety of psychological functions such as fear, mood, pleasure, and joy. In order for neurons to send messages throughout the body, they need to be able to communicate with one another to transmit signals. However, neurons are not simply connected to one another.
