These neurotransmitters are used by the brain to tell our heart when to beat, our lungs when to breathe, and even our stomach when to digest food. Neurons communicate with one another through their axon terminals. Axon terminals house synaptic vesicles, which contain neurotransmitter suspended in fluid, that cross the fluid-filled gap that is known as the synapse to reach the receptor sites on the opposite neuron. With it fitting into the receptor sites, neurotransmitters open the ion channels to let sodium rush in and activate the next cell to allow impulse so move from one neuron to the next (Ciccarelli & White, 2014). When neurotransmitters are fully functional they are fast and able to send messages throughout the body without any interruptions. However, when things such as alcohol are crossed into the blood stream, the neurotransmitter are affected. In his 2006 publication, “Alcohol, Neurotransmitter Systems, and Behavior,” Garvin Chastain, discusses how alcohol reduces glutamate release in the hippocampus which can result in impairment of spatial memory, and the ineffectiveness at receptors and the reduced transmitter release may produce lack of memory during intoxication. During intoxication the brain and neurons are affected the most, leading to slurred speech, impulsive behavior, and difficulty walking. Neurotransmitters can
