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 cells that communicate information. They are throughout the body but the vast majority are found in the brain. They receive messages through the dendrites; these are short branch like extensions that relay the messages to the cell body. The axon which is a thin long fiber extending from the cell body transports the message to near-by neurons. When the two neurons bond with each other, the axon of one cell comes close to touching a dendrite of the other neuron, leaving a tiny space called a synaptic gap or synaptic cleft. Then there is a release of chemicals called neurotransmitters from the axon terminal into the synaptic gap, the nerve impulses then travel across the axon terminal to its destination.

Brain Response of Behavior 3 or pick up a cup and bring it to our mouth. This process enables us to see birds fly, or feel the sand beneath our feet as we smell the salty air at the ocean through sensory neurons. Our movements’ entire voluntary, not voluntary, and our senses all come about because of this . The process of sending a signal from one neuron to the next involves the activation of a chemical messenger called a neurotransmitter, which is stored in sacs in the axon terminal. There are hundreds of neurotransmitters that have been identified by psycho biologists. (Tasman, 1997) Acetylcholine is excitatory neurotransmitters that play a part in our sex drive, how aroused we can be motivation, memory, how attentive we are this chemical is also located where neurons connect to skeletal muscles. Serotonin is an inhibitory neurotransmitter that affects mood. Dopamine is an inhibitory neurotransmitter. This can affect neurons with voluntary movement, learning, memory
