The objective of my assignment is to deliver detailed description of the approach in which neurons interconnect through one another. It explores the relation between this detailed communication and the behavior demonstrated by human beings to deliberate whether human behavior can be explained purely through biology. My paper will also identify the neurotransmitter that is associated with pleasure and its connection with developing an addiction.

The nervous system consists of various cells named neurons. Neurons are located inside the Central Nervous System instituting of the brain and spinal cord, and also inside in the Peripheral Nervous System. Neurons are cells that procedure and transfer information. Dissimilar mixtures of neurons compose neural systems that implement individual functions. A neuron includes of a cell body and a delay termed a procedure. Origination of an exploit prospective grounds rapid transference of electrical impulses along the neuron near the next neuron or cell and initiates action possibilities in a structure of neurons until it grasps the motor neurons which generate the muscles to effect an action. These sequences of action possibilities convey evidence rendering to the regularity of action possibilities in a neuron. The message attains at the spinal cord and transfers the evidence to the brain. Neurons do not connect physically. There are minute openings amongst neurons and cells this opening is termed a synapse. When the action possible grasps the presynaptic deadly, chemicals termed neurotransmitters, are rapidly quitted across the synapse to the postsynaptic neuron accordingly shifting the electrical possessions of the postsynaptic neuron. The message inside a cell is electrical yet amongst neurons the response is a compound one.

There is one of two possessions that a neurotransmitter can have; excitory, whereby the postsynaptic neuron is instructed to comportment an exploit possible and inhibitory where the postsynaptic neuron is commanded not to conduct an action possible. The synapse is the moment as a result of which another cell is stimulated by the neuron, and communication moreover continues or concludes. The neurotransmitter, equivalent with a lock and key, essential fit the receptor of the postsynaptic neuron, then it has no effect. Neurons are deliberated by the neurotransmitter they supply and relief, such as dopamine and serotonin. Once involved to a receptor, the neurotransmitter is quickly released then extracted from the synapse and moreover damaged by enzymes or taken back into the pre-synaptic neuron and damaged or reclaimed (re-uptake). Depiction on this information, it is now discovered how far behavior can be reduced to genetic phenomena. These two means of the message concluded the electrical and chemical are substantial as "changes in activity of the synapses can cause changes in neural a system, which in turn affects behavior, cognition and mood (Toates 2007).

A developmental effect when the synapses of the brain are influenced with a drug is the variations in mood accompanying with the use of cocaine. Equivalent to Prozac cocaine obstructs the reuptake of serotonin; however, the neurotransmitter elaborate is dopamine. The flow of dopamine in a drug addict's brain is what generates cocaine high. Where another transmitter called serotonin is accompanying with feelings of sadness, dopamine is associated with pleasure and elation. Dopamine can be elevated by persuasive pleasures that come from drugs, but also to a lesser degree by a word of approval or winning a tennis match etc. At a purely compound level, every involvement that human beings find enjoyable whether attending to music or appreciating
