The environment is an extremely powerful factor when it comes to physiological processes. The environment in which we are in is able to have surprising impacts on humans, as well as other animal’s physiological processes. Rosenzweig et al. conducted an experiment on mice to find out how the environment has an effect on the size of our brain. Another psychologist, George Brainard researched on the effects blue light has on humans. Both studies were able to show outstanding results on how the environment can have effects on physiological processes. Although the results seem to a point believable, there are always questions if there could have been other extraneous variables, which could be the reason for the results concluded in the experiments.
In 1972, Rosenzweig et al. conducted an experiment with mice to explore the effect that environment has on the size of the brain. Rosenzweig structured the experiment by having three different sets of mice, each with a different environment. The first set, was the control in the study, in which there were a number of mice with food and water. The second set of mice were in the impoverished set in which a single rat was with food and water, and the last set of mice, was the enriched set in which there were a number of mice, water food and different exercise machines and toys for the mice. At the end of the study when they looked at the brain size of the mice from each of the three sets, the ones in the enriched set had the thickest and heaviest cerebral cortices. They also found that the same set of mice had an increased activity of enzyme acytlcholinesterase, also that they had larger neurons and a greater RNA to DNA ratio, which is important for cell growth. Therefore, this experiment w...

...o blue light at night can also have some positive effects on our physiological process. Dr. Cajochen reported that subjects who were exposed to blue light scored higher on memory and cognition tests. Approximately only half the time, men where able to recall paired words which were flashed across a fluorescent light, while scored raised to almost 70% when the paired words were flashed though LED monitors.
In conclusion, scientists Rosenzweig and Brainard came close to proving that the environment you are living in can in fact, have effects on our physiological process. While on the other hand, scientist Olson showed that there are extraneous factors, which can alter the studies results, and Dr. Cajochen showed how exposure of blue light does not only have negative effects on us, but there can be some positive effects such as an increase in memory and cognition.

Essay about Bleaching of Coral is Harming the Environment

- ... Although some coral reefs may retain their physical structure, most still lose some of their framework due to physical disturbances (Coker, Pratchett and Munday). However, with coral bleaching threatening fish habitats, the larger the risk of extinction for these and other species will be. Therefore social hierarchies in the aquatic environment will change. This concludes that live corals are important for fish species than just a structure (Coker, Pratchett and Munday). In the Effects of coral bleaching, induced bleaching was performed by placing two colonies A....   [tags: color, global warming, environment]

Essay on The Coorelation between Drug Tolerance and the Environment

- The Coorelation between Drug Tolerance and the Environment When considering the dynamics of brain and behavior, another component that enters the equation is environment. If brain equals behavior then changes to either should result in an altercation to the other component. The question that arises is whether a change in the environment produces change in brain chemistry and therefore, behavior. A connection between brain, behavior and environment may be observed in the context of drug tolerance....   [tags: Drugs Drug Environment Essays]

The Physiological Advantages and Disadvantages to Athletic Sports Performance

- Introduction Blood doping, or induced erythrocythemia, is a term used to describe any means by which a person’s total volume of red blood cells is increased (Wilmore, 1994). The strategy has been adopted by a number of athletes, with positive results in endurance sports such as cycling, cross-country skiing and long-distance running. Whilst a fairly small increase in erythrocyte mass is seen in athletes after months of endurance training, dishonest athletes may strive to increase their erythrocyte mass further through the illegal and unethical processes blood doping or administration of human recombinant erythropoietin (rHuEPO)....   [tags: Pro Con Essays]

Homeostasis : A Stable Internal Environment Essay

- ... Therefore, feedback mechanisms adjust the balance of insulin and glucagon so it may maintain a physiological function. These peptide hormones can only be made in the Islets of Langerhans, which is a special group of cells located in the pancreas. Seven different types of cells are contained in the islets but the important ones are the Alpha cells and Beta cells. Alpha cells detect when the blood glucose falls below 70 mg/dl and release glucagon. Glucagon stimulates the conversion of glycogen into glucose as to increase blood glucose level....   [tags: Blood sugar, Insulin, Islets of Langerhans]

Physiological Processes And Its Effect On A Stable Internal Environment Essay example

- 1. A. Homeostasis is the ability for the body to maintain a stable internal environment, despite changes that can occur in external conditions. A typical feedback loops has three main components that make it function. 1) Receptor, which regulates changes in a controlled environment and sends information to the control center. 2) Control Center, which compares incoming input with other information and informs the effector, for a change to occur. 3) Effector, acts on the changes and releases the response....   [tags: Neuron, Nervous system, Action potential]

Changes in the Environment Affect the Behavior and Physiological Aspect of an Organism

- The changes in the environment affect the behavior and physiological aspect of an organism. One important concept that further supports such phenomenon is heterochrony. Heterochrony is described to be the evolution of ontogeny, which is the development of an individual from its earliest stage to maturity. It takes hundreds, even millions of years for evolution to occur. By studying the earliest chordates, one would be able to relate the changes and adaptations that have emerged to sustain life of primates today....   [tags: heterochronic processes]

The Effects Of Consciousness And Its Effects On Our Lives Essay

- ... While some refer to circadian rhythms as a single process, there are actually many body clocks that oscillate throughout the day which a small group neurons in the hypothalamus govern. This master control center, known as the suprachiasmatic nucleus acts as the body’s internal pacemaker. Sunlight and lack thereof are perhaps the most evident, regulating our daily sleep-wake schedule. Disrupting this cycle can lead to insufficient and difficult sleep. For example, before starting school this fall, I was mostly in bed by 10:00pm and waking up for work about 7:00am to prepare for the day....   [tags: Altered state of consciousness, Sleep]
