The brain is the control center for many actions that occur in the body. Its ability to conduct complex processes is due to the interconnecting of its 100 billion neurons. Neurons are able to communicate with each other through the neurotransmitters that are released at specialized junctions called synapses. These synapses are found in two locations where the pre-synaptic terminal is found at the tip of an axon and the post-synaptic terminal is on the dendrite. These two membranes line up against each other separated by a small gap about 20nm wide. The narrowness of the gap allows the neurotransmitters to pass quickly from one another. The release of neurotransmitter from the pre-synaptic nerve terminal is caused by the appearance of an action potential. When an action potential arrives at the synapse, it results in the calcium ion channels to open. The movement of the calcium triggers the release of neurotransmitters through a process known as exocytosis. The neurotransmitters......
