The Central Nervous System Mindset Essay

Neurons are electronic cells that bring and acquire information and will be the building blocks of our own central anxious system. Neurons have two parts to them, the cell body and the process. When many neurons are grouped mutually they form a neural system which will carry out a function such as engine control. How neurons pass on information with each other is via something called the synapse (Toates, 2007).

Neurons are mainly positioned in the mind but can be found throughout the body especially the spinal-cord; the brain and spinal cord together form the central stressed system and neurons outside the central nervous system form the peripheral stressed system. To make clear how the neurons communicate between the peripheral nerves, spinal cord and brain a good example would be if a foot was put in a hot bath the neurons on the foots skin (peripheral nerves) would serve as a detector which would set off an electrochemical reaction, this change in electrical activity is named an action potential. These neurons are biologically designed to quickly pass a power signal into the spinal cord, through a communication network with other neurons, and the leg muscle which causes the reflex for taking the foot from the hot water. The group of neurons that do this are called the engine neurons; in the meantime within the spinal cord neurons are interacting with each other up towards the brain to alert that this should be painful hence the scolding feeling (Toates, 2007).

In the brain a neuron is linked to between 10, 000 and 20, 000 others, conversing through a gap called the synapse. An action potential trips along the presynaptic neuron (the mailing neuron) until it grows to the gain access to terminal (the finish of the neuron) which in turn causes a chemical substance release called neurotransmitter, these chemicals travel over the synapse to the receptors on the postsynaptic neuron (the receiving neuron). The neurotransmitter on the presynaptic neuron must be considered a match for the postsynaptic neuron receptor or inhibition could happen. Inhibition is the increased loss of the action potential from one neuron to the other and would lead to reuptake which is when the presynaptic neuron calls for back the neurotransmitter which it experienced released (The Open up College or university c2007).

The biological psychology of behavior is deterministic and expresses that neurons in the brain are the map of our own mental life. This consists of that hormones have an impact on the nervous system and have an effect on behaviour and feeling; it also expresses that there surely is a two way relationship between neuron activity and behavior. To look at the result that the neurons in the mind have on behavior this essay will now look at the three main neurotransmitters, and put an argument against a natural biological psychology standpoint.

The three main neurotransmitters are serotonin, acetylcholine, and dopamine. Serotonin affects mood; a lack can lead to depression which is believed to be credited to a substance imbalance of the serotonin in the mind, and to obsessive-compulsive disorder, anxiousness and other anxiousness disorders, stress, and can cause upset or violate outbursts. This is because the neurons which are serotonergic (the neurons that release the neurotransmitter serotonin) would need the postsynaptic neuron to possess receptors for serotonin or reuptake from the presynaptic neuron could happen (Toates, 2007).

According to Gov. uk (2012) depression is often cared for by antidepressants called selective serotonin reuptake inhibitors (SSRIs) such as Citalopram (Celexa), Escitalopram (Lexapro), Fluoxetine (Prozac, Prozac Regular, Sarafem), Paroxetine (Paxil, Paxil CR, Pexeva) and Sertraline (Zoloft) these are selective as they mainly influence serotonin neurotransmitters. Toates (2007) advised that SSRIs stop the reuptake of serotonin which contributes to the postsynaptic neuron getting the serotonin thus helping rebalance the uptake and increasing basic well-being.

Acetylcholine is thought to responsible for memory and muscle movements; people who have problems with ailments like dementia and Alzheimers might well have a deficit in acetylcholine or the postsynaptic neurons efficiency to uptake. Dopamine is partly in charge of movement, attention and learning; people who have problems with Parkinsons disease are believed to acquire depleted levels of dopamine which cause the symptoms to the disease such as physical motion (motor symptoms) ambiance, thinking and behaviour (neuropsychiatric symptoms) and the autonomic stressed system (which control buttons respiration and urination). An excessive amount of dopamine is common in schizophrenics which is cared for by several drugs called phenothiazine antipsychotic which blocks the surplus dopamine (Benson, 2007).

This highlights behaviours from a natural standpoint but does not consider other exterior factors to, for example for depression. It could be argued that behaviour is somewhat inherited, and therefore if two parents that suffered with depression there could be an increased chance the kid would. So you might consider it from a mother nature versus nurture view point, though it is now more prevalent (through research) to observe that if you were genetically disposed to depression but your environment or life situations didn't trigger the depression then you cannot say this is dynamics (since it has not occurred), and vice versa; a far more agreeable argument is that it's nature via nurture (Jarrett, 2011).

The biopsychosocial model (BPS) takes into account all aspects of the possible depression as the biology could potentially be the result and not the reason. For an extreme example if a person was a victim of domestic violence, lived in a bedsit in a unwanted part of town after having their house repossessed and was frustrated then medication would not stop their partner reaching them or get them rehomed; cognitive behavioural therapy (CBT) which often people get referred to alongside antidepressants won't help either (although other communicating therapies may help them dwelling address issues and explore options they have). So only by looking at the biological, internal and the communal situation can you really fully identify where in fact the behaviour is stemming from and work from there. (Toates, 2010)

To conclude, natural mindset, especially how neurons communicate with the other person within the stressed system, has added greatly to your understanding of human being behaviour however the deterministic standpoint will not take into account several other factors which could affect behavior and without taking a look at the individual holistically of their social setting, then your way neurons function may have little impact on the presenting issue of a persons behavior.
