The first effect of an environment on physiological processes that will be discussed is brain plasticity. Blood samples were taken before and during their exams. Another example of a study investigating environmental enrichment on brain plasticity is an study conducted by Draganski et al.

The group injected with scopolamine was slower at finding their way around the maze and made more errors than the control group.
Certain neurons that typically fire in response to pain also fired when the person saw someone else in pain. Genie was a remarkable girl who used non-verbal communication to connect with others. Only students were used in the sample. Moreover, Kiecolt-Glazer showed how chronic stress may reduce immune system.
Students were given survey for self assessment on psychiatric symptoms. Anxiety level remained the same throughout the entire experiment measured a stress hormone. Thus this study shows that acetylcholine affects the human behaviour of memory causing an increase in memory functions with higher amounts of acetylcholine compared to lower levels of acetylcholine, which decreases memory functioning.
The studies by Maguire et al and Curtis both demonstrate how being in an enriched environment, one where opportunities for learning are stimulated and supported, can affect brain plasticity and dendritic branching for the best.
Connection of study to question This study showed the effect of the environment on physiology because more enriched environments helped develop neurons in brains of the rats.
There was no longitudinal study of effects or results.
Compared the brains of professional musicians who practice at least 1 hr. The rats were separated and exposed to the two environments for days before being euthanized. 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.
Discuss one example of how the environment can affect one physiological process. Their aim was to determine the role of acetylcholine on memory, specifically memory formation. In conclusion, both the beneficial and damaging effects of the environment on our physiological process mostly on the processes on our brain was discussed.
All of the taxi drivers were described as having healthy general medical, neurological, and psychiatric profiles. Keysers Introduce Study - Connection of study to question: On the contrary to the positive effects of the environment, there are negative effects of the environment on the brain as well.
Mirror neurons cannot be directly observed in humans because electrodes cannot be inserted into their brains.
The second main finding was that hippocampal volume correlated with the amount of time spent as a taxi driver. Light received by the optical nerve in the eye causes a signal to be sent to the Suprachiasmatic Supra-chias-matic Nucleus SCN.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.
The first effect of environment on physiological processes that will be discussed is brain plasticity.
