Discuss the effects of the environment in physiological processes essay

Anxiety level remained the same throughout the entire experiment measured a stress hormone. However, some critics argued that those PSTD patients most likely also suffer from other mental diseases as well; thus, it is hard to attribute the cause of hippocampus size reduction to chronic stress only.

You must evaluate the studies you present. However, if the stress response is prolonged, it is said to have devastating effects on our physiology. Light received by the optical nerve in the eye causes a signal to be sent to the Suprachiasmatic Supra-chias-matic Nucleus SCN.

The two effect of the environment on physiological processes that will be discussed are the enrichment of certain environments on brain plasticity and the observation of experiences actions on the activation of mirror neurons.

Overall it can be seen that neurotransmitters do affect human behaviour in a variety of ways. Gaser and Schlaug Introduce Study - Connection of study to question: Another example of a neurotransmitter is acetylcholine. This finding indicates the possibility of local plasticity in the structure of the healthy adult human brain as a function of increasing exposure to an environmental stimulus.

This study showed the effect of the environment on physiology because more enriched environments helped develop neurons in brains of the rats. This led to the observation that some neurons responded in the same way when monkeys saw a person pick up a peanut as when they are doing it themselves.

Voxel-based morphology VBM was used in this study to measure the density of grey matter in the brain. Plasticity occurs every time something new is learnt Brain plasticity is explicitly shown after brain injury when the brain reorganizes and forms new connections with healthy neurons to compensate for the functions of the damaged area.

A newer technology called functional magnetic resonance imaging fMRI produces a picture of neural activity averaged over seconds, not minutes, and the images can identify much smaller brain structures than those in PET scans.

It is associated with the brain — in how it involved in learning and memory. The group injected with scopolamine was slower at finding their way around the maze and made more errors than the control group.

Serotonin stimulates neurotransmission in the post-synaptic neuron, increasing arousal, emotion and is also implicated in depression. The research studies above demonstrate that the more a person performs a particular activity, the more neural connections are formed in the area of the brain responsible, creating a physical change in the brain.

More Melatonin is released when there is no sun, causing drowsiness making the person sleepy. Asked participants to look at human faces while in an fMRI. Brain damage caused by accidents such as to K. You can use PowerShow.

Lingau et al Lingau et al did not find mirror neuron activity for acts that were first done and then observed, only the other way round. And, best of all, most of its cool features are free and easy to use.

Kiecolt-Galser et al — Stress in exam study Work-related stress [A] Investigate the stress from examinations and its effect on the immune system. Although the stressors which are often referred to in this video are not the same as the women studied by Bremner et al you can see the same classic PTSD pattern in the experiences described by the soldiers.

InSimon et al. As he analyzed the volume of the hippocampus using pixel counting, Maguire found out that the taxi drivers had larger posterior hippocampus compared to the control. Assumption made on concluding, that death is cause by changes in body rhythm.

To investigate the effects of a deprived or enriched environment on neuroplasticity, in particular, the development of neurons in the cerebral cortex. The second main finding was that hippocampal volume correlated with the amount of time spent as a taxi driver.

Since acetylcholine is well known to increase memory by the study Martinez and Kesner Plasticity occurs every time something new is learnt and it is explicitly shown after brain injury when the brain reorganizes and forms new connections with healthy neurons to compensate for the functions of the damaged area.

He put his volunteers in a brain scanner and wafted disgusting odours For example, rancid butter and rotten eggs into their nostrils He wafted some non-disgusting ones too, as a control Results: This represents the bidirectional relationship between the environment and physiological processes occurring in the brain.

Give background info and define concepts if not commonly known.The two effect of the environment on physiological processes that will be discussed are the enrichment of certain environments on brain plasticity and the observation of experiences actions on the activation of mirror neurons.

Thus, in this essay, both the beneficial and damaging effect of the environment on the brain and its ability to think and its memory capacity will be discussed by referring to the enriched environment and stressing environment.
