: Communication Process of Neurons in the Brain.

Provide a 5 pages analysis while answering the following question: Communication Process of Neurons in the Brain. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. The cell body contains the cell nucleus and accepts incoming messages from dendrites. It passes the message on to the axon if it receives sufficient stimulation from the dendrites.&nbsp.(Huffman, 2008)

Axon is like a long, tube-like structure and acts like a miniature cable which carries information and impulses away from the cell body.&nbsp.(Huffman, 2008)

Communication between neurons is an intriguing process and one that very different from the method of communication within the neuron. Communication between neurons is transmitted chemically as opposed to electrically within the neuron. The transfer of information between the neurons occurs at the synapse which includes the tips of the axon (terminal buttons), the synaptic gap (tiny space between the neurons) and the receiving neuron’s dendritic branches.

Low levels of Serotonin are associated with depression. They are known to suppress pain and regulate temperature. Other impacts include mood, appetite, sleep and sensory perception.Dopamine plays a role in addiction and the reward system. Excessive levels of dopamine are associated with Parkinson’s disease, while too little levels are associated with schizophrenia.&nbsp.

The process starts with the release of a few thousand chemical molecules (neurotransmitters) into the synaptic gap by the sender neuron’s axon. These neurotransmitters then move towards the dendrites of the receiving neuron across the synaptic cleft. This neurotransmitter then attaches itself to the receiving antenna of the neuron and delivers either an excitatory or an inhibitory message.&nbsp.(Huffman, 2008)Norepinephrine impacts dreaming, waking from sleep, alertness, reactions to stress, learning and memory. High levels of Norepinephrine are associated with agitated, manic states while low levels are associated with depression.Epinephrine affects memory storage, metabolism and emotional arousal. It also majorly impacts the glucose necessary for energy release.

Endorphins, effect-wise, are similar to opium-based drugs such as Morphine. They promote pleasure and reduce pain.
