The Effects Of Caffeine On The Brain Function

Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are

Caffeine, a popularly consumed central nervous system stimulant is consumed on a day to day basis around the globe. Caffeine can be ingested into the body by either eating it or drinking it. Caffeine comes in forms of many processed foods such as coffee, chocolate bars, candy, sodas, and energy drinks as well as tea. For example millions of people all around the world consume coffee on a daily basis. Due to the large consumption of caffeine, both the negative and positive side effects of consuming it have been well researched and documented. However the long term effects are much more significant, the short term side effects of caffeine may not appear to be as extreme. The regulation of caffeine consumption is crucial in order to guarantee that one does not become dependent on it, and to ensure that an individual’s body will not be damaged by doing so. The evidence that backed up the claim that coffee is best consumed in small amounts and not on a daily basis is overwhelming and clearly shows that coffee consumption must be carefully regulated and controlled.

Introduction: Have you ever experienced the jittery feeling after drinking too much pop or coffee? You’re suddenly filled with tons of energy and sitting still feels almost impossible. You have most likely experienced this feeling whether it be from eating too much candy, or having too many caffeinated, sugary drinks.

Caffeine is an alkaloid discovered in 1819 by Friedlieb Runge and a German baron known as

Johann Wolfgang von Goethe. Caffeine is a crystalline compound that is found in tea and coffee plants

Many people start their day with a cup of coffee. According to John Hopkins, “Around 90 percent of Americans consume caffeine every single day in one form or another”. It seems if we need a wakeup call to our morning, many of us grab caffeine to give us that extra boost of energy. How much caffeine is ok for the average person each day? The Dietary Guidelines Advisory Committee from Healthgov.com recommend 3-5 eight ounce cups of coffee per day or up to 400 milligrams per day of caffeine for the average healthy consumer. Caffeine is a CNS stimulant drug known as trimethylamine. Caffeine is naturally found in chocolate, coffee, cocoa beans, kola nuts, and tea. It is also added to drinks such as soda and

Caffeine disguises as adenosine in the brain. Adenosine tells your body to slow down when it’s time to sleep. The caffeine gets into the bloodstream and stimulates the central nervous system. Way over a week caffeine causes a person to become more alert, react faster, and feel like the person is not working as hard. Caffeine can also cause reduced brain growth. It causes someone’s mind to race and makes it hard for them to concentrate. A person does not get a burst of energy directly from caffeine. It blocks the message from your brain to your body that you are tired. Caffeine blocks off the want to sleep and rest. The result of this is the rise of alertness and wakefulness caused by the release of dopamine and glutamate. Caffeine in a person's body modifies the brain's capability to make good, healthy choices by moving function to the lower part of the brain from the upper part of the brain. Concerning other parts of the body, caffeine can cause both high heart rate and blood pressure. Caffeine can impact

As people around the world discovered caffeine in their native vegetation, various cultures concocted drinks or chewed on the plants leaves to experience its effects. 90% of the world consumes caffeine daily and in each of those billions of humans, caffeine spread itself throughout their bodies and enters their brains. So how long does caffeine stick around in the body? The half-life of caffeine, or the time it takes of half of it to be broken down, is between five and six hours on average in adults. As the caffeine gets broken down, what does it become? Pure caffeine is a powerfully bitter white powder. So if caffeine is affecting the brain in so many ways, why isnt caffeine powder being snorted alongside coke or shot alongside heroine? Caffeine

There are many foods and drinks with caffeine found in them. For example, caffeine can be found in certain drinks such as, “Coffee, tea, caffeinated soda, and energy drinks. Some certain caffeinated soft drinks are Pepsi, Coca-Cola, Sunkist, and Mountain Dew. Also some energy drinks that caffeine may be found in are Redbull, Full Throttle, and Monster.” (Caffeine, para 2, 2015). Also, another example of sources of caffeine is that caffeine can be found in food, such as, “Caffeine is found in chocolate.” (Gavin, para 3, 2014). However, caffeine is not only in foods and drinks, it can also be found in medicines. For instance, Caffeine helps people with many medical issues, “Caffeine is sometimes consumed by many adults in order to kickstart medicine taken before hand. It improves the effect of many medications and is used for headaches or migraines.” (Bryant, para 21, 2015). In addition, caffeine can help a human with other things, “Caffeine that is treated with a citrate of potassium or sodium, can help breathing in premature babies. Also, it can help some children that suffer breathing problems, by helping them breath better.” (Bryant, para 20, 2015). So, basic sources of caffeine are coffee, tea, caffeinated soft drinks, chocolate, and

Adenosine is a natural substance in our body which is sent to the brain to calm down some nerve cells that are too active. Unfortunately when caffeine enters the body, it tries to pass through the same channel the adenosine uses to calm the

Caffeine is a psychoactive drug enjoyed by many people every day around the world and some people love the feeling they get from it, while others regard caffeine as a drug that manipulates the mind and readiness of its prey. However, many fail to understand the way that it works or don’t even know its origins. The most notable discover would be a German scientist Friedlieb Runge in 1819 that was able to not only isolate but also synthesis caffeine from its various products that it is found in, “Pure caffeine”. The form would be a crystal looking substance similar to that of sand. Pure caffeine is a form of methylxanthine alkaloid that has a bitter taste, and the crystal looking of pure caffeine was a purine that is a white purine. However, caffeine

1,2,7-trimethylxanthine commonly known as caffeine is the best known N-compound due to its physiological effects on the central nerve system, blood circulation and respiration. Caffeine is the most widespread consumed behaviorally active substance and almost all the caffeine sources are dietary (Fredholm et al. 1999). The caffeine content of e.g. coffee differs depending on the Coffea variety and the content only decreases in small amounts during roasting (Belitz et al. 2009). In the US Coffee consumptions contributes to 71% of caffeine intake among adults (O'Keefe et al. 2013), however caffeine can also be found in tea, cacao, chocolate as well as sodas. It is found that most notable changes in the behavior occur after low to

Caffeine, a cardiac stimulant, is the most popular drug in America with 90% of the population consuming it everyday to get their daily boost of energy. The feeling we get after drinking a caffeinated drink are due to three things: caffeine, adrenaline, and dopamine. Caffeine binds to adenosine receptors in the brain. Adenosine is a chemical that builds up in our brain all day and is to thank for making us tired. When caffeine binds to these receptors on brain cells, the cells speed up, causing us to feel alert.

Caffeine Effects In The Brain Caffeine acts in a multitude of ways in the brain. The most recent studies explore the cooperative effects of adenosine and dopamine, as well as the increase in calcium in the interstitial fluid and possible accumulation of cyclic adenosine monophospate. The most popular discussions of earlier studies of caffeine demonstrate its antagonistic effects on adenosine receptors. While it has been reported that adenosine receptors are located throughout the brain, the various subtypes can be found in very specific areas.

The mechanism of caffeine involves the inhibition of enzyme phosphodiesterase, which degrades cyclic AMP and this is permitted due to caffeine’s structural similarities with adenosine. The caffeine molecules bind to the adenosine receptors in brain cells and block adenosine from binding. Adenosine plays a role in the sleep-wake cycle. When adenosine binds to enough receptors, it signals the brain that it is time for rest or sleep. Caffeine does not replace the need for sleep, but prevents drowsiness or sedation symptoms that adenosine causes. Since caffeine blocks the degradation process of cyclic AMP, caffeine indirectly affects regulation of cAMP-dependent protein kinases, which are responsible for the regulation of glycogen, sugars and
