What Goes Wrong

computer circuits are hard-wired at the factory. A computer s circuitry never changes. In contrast, as we noted previously, brain circuitry is constantly adapting through a process of pruning and reestablishing connections. This pruning affords the nervous system a plasticity that enables it to adapt continually to the demands of an ever-changing environment. 

The importance of brain circuitry is that it reminds us that these chemical neurotransmitters are not released willy-nilly throughout the brain. This is why the term chemical imbalance is so unsatisfactory. The brain is not a large water bottle into which these chemicals are poured and maintained in some precise balance. For that reason, there is no simple test to check a neurotransmitter level like the dipstick on your car s oil reservoir. Instead, your brain is a delicate instrument with predefined but ever-adapting pathways of communication. 

Each of these pathways (or circuits) serves a particular purpose and works in concert with other circuits. Technology has only recently allowed us a glimpse of these circuits in action. Thus, we are just beginning to map out the pathways and functions of the myriad brain circuits involved in the regulation of thought and emotion. As you ll see later, however, understanding brain circuitry can help us to anticipate what the beneficial effects and side effects of a medication may be. 

By now, you know that the nervous system is a communications network that serves to control your body. You also know that nerve impulses are the vehicle that carries information around this network. In addition, you know that chemical neurotransmission is the means by which these signals are passed from one neuron to another. Finally, you know that neurotransmitters, receptors, and enzymes are the key components that make all of these things happen. 

We have long suspected that abnormalities in the receptors and enzymes that interact with a neurotransmitter are one of the major underlying causes of many
