Brain Response of Behavior
Part I
Note: Parts II and III follow below, complete all three.
Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior.
Neurons are electrically excitable cells found in the nervous system, which is mainly responsible in the transmission of information between the neurons and the cells. With the neurons, all body systems are able to communicate with the brain through sending and receiving signals and a connection within specific regions of the central nervous system is established. To be able to attain its function, neurotransmitters are needed by the neurons so that signals between a neuron and a cell are relayed, amplified and modulated. Neurotransmitters are chemicals released by a neuron at the presynaptic nerve terminal by which movement across a small gap called the synapse facilitates accomplishment of communication of information between the neurons and the other cells. These neurotransmitters have various functions, which include regulation, stimulation, motivation, transmissions and inhibitions of different body functions. Neurotransmitters play major roles in regulation of moods, emotion, affect, sensory functions, and perception thus has great impacts on behaviour. Common neurotransmitters that can affect the behaviour include dopamine, serotonin, and norepinephrine. Dopamine is released in different parts of the brain usually released by naturally rewarding factors such as food, sex, and drugs. It has stimulating effects and performs many functions including important roles in behaviour and cognition, motivation and pleasure, sexual arousal, regulation of sleep, mood, attention, motor activities, and learning. Serotonin also controls mood and behaviour including sexual and hallucinogenic behaviours, appetite, sleep, memory and learning.
