...would be, that is, if not for the neurotransmitters. These chemicals are stored in tiny sacs known as vesicles, located at nerve endings. When an electrical signal reaches the vesicles, they release their load. The neurotransmitter molecules navigate across the synapse and lock into receptors on the neighboring nerve cell--an action roughly equivalent to flipping on a light switch. The second nerve cell wakes up and sends off a jolt of electricity to pass the message along. Their job completed, the neurotransmitter molecules detach and are ferried back to be reabsorbed or destroyed...
...effects vary widely, however, depending on a variety of factors. To begin with, each neurotransmitter can latch onto more than one kind of receptor. As many as 15 distinct receptors have been identified for serotonin alone. And since a given nerve cell may have more or fewer receptors, depending on where in the brain it is located, a jolt of a particular neurotransmitter can generate electrical signals of widely varying strengths. Small wonder, therefore, that serotonin can affect everything from satiety to depression...
