The Effect of Caffeinated Drinks on House Mice
People all over the world consume caffeine daily. Caffeine, a component of coffee, tea and cola, is a white crystalline and bitter alkaloid which acts as stimulant or diuretic (Wallace, 1990). Caffeine affects the central nervous system by stimulating nerve cell metabolism which improves performance, increases alertness and decreases boredom. According to Campbell (2011), the central nervous system is the portion of the nervous system where signal integration occurs, specifically the brain and spinal cord for the vertebrate animals.
The effect of different caffeine products will be determined using the automated counting system in wheel activity. House mice will be used as the test organism as it is fit to the wheel activity test. House mice also have a high degree of homology with humans and are cheaper and can be easily maintained. If the caffeine content from energy drink and coffee increases the wheel activity of house mice, then the mice on a caffeinated diet will have higher rate of wheel activity than the mice on a non-caffeinated diet. Since house mice are usually used as test organisms for medical researches with results that can be applied to humans, comparing the effect of caffeine on humans and house mice can be observed. This study aims to determine the effect of different caffeinated drinks on the activity of the house mice through the wheel activity test. The specific objectives are: 1. identify the effect of caffeine on the mice’s central nervous system; 2. compare the wheel activity of mice using different caffeine products; and 3. determine which caffeine products is more effective in increasing the wheel activity of mice.

    Caffeine is a stimulant which is derived from leaves, flowers and seeds of plants. The plant uses the caffeine as a way to repel insects as it is used as a natural pesticide by paralyzing and killing certain insects. It is used as a stimulant to human the central nervous system by increasing the stimulatory of the neurotransmitters, however high levels of caffeine to the body can cause effects of insomnia, stress, anxiety, weight loos or high blood pressure. In this investigation the effect of caffeine was observed on Daphnia [figure 1] a water crustacean, commonly known as a water flea, normally found in a aquatic areas like ponds, lakes, streams or rivers. They were used because this species of water fleas has a transparent exterior and it is easier to observe the heart rate of the Daphnia through the microscope.…

    Caffeine is a bitter, white crystalline xanthine alkaloid that is a psychoactive stimulant drug. Caffeine is found in varying quantities in the beans, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the cherries of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. In humans, caffeine has a stimulant effect, causing increased amounts of stimulatory neurotransmitters to be released. If the consumption of caffeine is…

    The purpose of this laboratory exercise was to demonstrate and explain the effects caffeine on the circulatory system of blackworms and to test the hypothesis that high concentrated caffeine will double the heart rate pulsation of blackworms. Blackworms have several complex systems including a closed circulatory system: a complete digestive tract: and a nervous system, including a brain and a cord. Because of the transparent skin of the blackworm, its large dorsal blood vessel is very easy to see through the microscope. Since the rate of pulsation is easily seen and calculated it’s easy to test the effects of different chemicals on their cardiovascular system. Since it’s known that caffeine increases the blood pressure one might expect that the blackworms under the influence of caffeine will show a grater average of pulsation rate.…

    The placebo controlled experiment design can be helpful in this study. In order to determine the effect of caffeinated energy drink, the total of twenty athletes will volunteer to participate in it. All the participants will be divided into two groups; ten will drink caffeinated energy drink and other ten will ingest placebo (no caffeine content). The drinks will be served in an opaque bottle to avoid its identification and to make sure that player drink beverages in it entirely. Both the drinks will have same appearance, taste but different caffeine content. Each participate will be required to take part in two trials under the same experimental conditions and standards. The both trials should be performed at the same time of day to avoid the effect of circadian rhythms in the variable. For the study, the participants will ingest caffeinated energy drink according to their body mass and sixty minutes before their performance. The sixty minute timeframe will help the caffeine to absorb completely in the body. The next trial will take place after one week from the first trial as this time period will allow the caffeine to washout from the body. Sixty minutes after the consumption of caffeinated energy drink and placebo drink, their performance will be accessed to find out the outcomes of these drinks on the strength.…

    The stimulant effect of coffee comes from the way it acts on the adenosine receptors in the neural membrane. When adenosine binds to receptors, neural activity slows down, making you feel tired. Caffeine acts as an adenosine-receptor agonist, this means that it binds to the same receptors, but without causing slowed neural activity. The…

    The problem for this experiment is how does the amount of caffeine affect the speed and performance of a mouse. The hypothesis is if the amount of caffeine consumed by the mouse is increased, then the time at which the mouse completes a set obstacle course will decrease when time is a function of caffeine quantity. The amount of caffeine consumed by the mouse before completing the obstacle course is the independent variable. The dependent variable of the experiment is the amount of time the mouse takes to complete the course. The obstacle course, the substance from which the caffeine is obtained from, the amount of time the mouse is given to digest the caffeine, and all other environmental conditions are controls. The overall experimental control,…

    Un-Prescribed Study Drugs

    Caffeine can be consumed through coffee, tea, energy drinks, or caffeine supplements. Regardless of the form in which it is taken, caffeine has some effect on cognition. For example, a study conducted by Warburton (1995) found that caffeine intake results in increased alertness, concentration, and memory. Admittedly, there are parallels between the effects of caffeine and study drugs in relation to improved academic performance. It is understandable why critics present this argument because if both are influencing cognitive abilities to a certain extent, then both should be treated equally. However, a line must be drawn. On the surface, the effects of caffeine and ADHD/ADD medications may seem similar, but on a neurological level, the differences are significant. As previously mentioned, study drugs bind to dopamine and epinephrine receptors whereas caffeine binds to adenosine receptors (Doyle et al, 2010). This can influence how long the effect of the stimulants will impact the body. For example, the effects of caffeine can last up to six hours (University Health Service. (n.d.)) in the body whereas Adderall can last up to 12 hours in the body (Brams, Moon Pucci & López, 2010). The differences are significant and it is too far-fetched for the two to be compared. A stimulant that is in the morning cup of coffee or tea should not be compared to medications that are legally prescribed to patients with neurobehavioural…

    The experiment aimed to establish a correlation between caffeine intake and the effects it has on both the pulse and respiration rates of an individual after undergoing moderate-intense cardiovascular exercise. Caffeine itself is one of the most heavily consumed drugs on the planet; it is estimated that over 90% of Americans consume caffeine daily (Richard Lovett, 2005, New Scientist iss. 2518) and is the most widely used stimulant in the world (Arcerio, P, Ormsbee, J, 2009, pg. 1). Caffeine stimulates the brain and behaviour, whilst enhances performance at simple intellectual tasks and at physical work that involves endurance (Alcoholism and Drug Addiction Research Foundation, 1991). Coffee is one of the most commonly digested sources of caffeine, and approximately 6g of coffee will contain 180mg of caffeine (University of Sydney School of Biology, 2010). Many studies have taken place to try and examine the effects of caffeine on enhanced endurance for athletes, the study “Performance and metabolic responses to a high caffeine dose during prolonged exercise" (Graham, TE; Spriet, LL (1991) indicated that endurance levels in trained athletes increased by as much as 44% after ingestion of caffeine. This suggests that in our experiment we will perceive an increase in performance in our subjects over the duration and upon completion of the moderately-intense cardiovascular exercise, showing that caffeine will alter the mean change in pulse and respiration to a significant degree…

    Dated back to the 1400s and possible earlier people have been drinking caffeine to include coffee, tea, and chocolate. Today, caffeine is one of Americans’ favorite substance also including the soft drinks and the energy drinks. Per Hart and Ksir (2015) by 2009 Americans were consuming less caffeine; 45 gallons of soft drinks and 23 gallons of coffee when compared with 49 gallons of bottled water per person. Although declining, soft drinks and coffee are still a major part of American’s caffeine consumption, “it is estimated that 80 percent of Americans regularly use caffeine in some form,” (Hart & Ksir, 2015, p. 261). But the Food and Drug Administration (FDA) has not challenged its regulatory oversight on the caffeine use since the 1980s. Adults caffeine use is not of great concern by the FDA because there is no caffeine use disorder, the caffeine is responsible for long-term health benefits, and the caffeine is safe for most adults. Therefore, I consider the FDA current lack of restrictions on caffeine use sufficient and fair.…
