Effects of Caffeine
There are effects of caffeine shown in molecular imaging with positron emission tomography (PET). Scientists have for the first time been able to visualize the sites of caffeine in living human’s brain. They have explored possible positive and negative effects of the caffeine consumption. Scientist research was published in the Journal of Nuclear Medicine. They showed images of F-18-8-cyclopentyl-3-(3-fluoropropyl)-1propylxanthine (F-18-CPFPX). In which all show the intake of the caffeine beverages we take in each and every day. Humans taking in so much caffeine, results in up to fifty percent of an occupant brain’s A1. The effects of the caffeine are attributed to the cerebral adenosine receptors.
I learned that the intake of caffeine does have a substantial effect to a human brain. Caffeine is the most commonly consumed psychoactive substance in the world. It is an active ingredient in most of our food and beverages. Eighty percent of the U.S. adults consume caffeine each every day with coffee and soda. The effects are known to show in the brain’s A1. So with consuming caffeine on a regular base can affect a person’s alertness, attention, performance, and also reduces sleepiness. I have concluded to stop drinking caffeine myself before this blog entry.
What does caffeine do to your attention and performance? How does caffeine affect your alertness? I thought caffeine was suppose to keep and alert and focused this is why I ask. Amanda Dollman
ReplyDeleteWhy does taking in caffeine susubstantial effect to a human brain what does it do to our brains? Why was Scientists able to see the sites caffeine in a living brain? Was it because our brain stay active and is always working and makes us think. Thats the reason I as the question and was wondering about the effect on caffeine.

Amanda I agree with you on your question that you ask on this topic. I also thought that caffeine was suppose to keep you up and alert. But isn't caffeine also bad for you if you drink to much.Sometimes when you drink caffeine doesn't that effect the way that you sleep too.but I have to have my caffeine even if sometimes drinking to much is bad for you I love my caffeine that is in soda :).

ReplyDeletethink this article is very interesting, because it is talking about Caffeine which effects our everyday life, because as mentioned in the article 80 percent of adults give or take have caffeine incorporated to their everyday life. I liked that you specifically stated caffeine can contribute to a negative effect on the human brain. I did not like however that you did not explain how caffeine has an impact on our brain. I would have really enjoyed learning about the process of Caffeine's effect on our brain. All in all very good job.

ReplyDeleteYour article is interesting, but the last comment on your article makes me wonder why you stopped consuming caffeine. From what you said, caffeine is very helpful to people, especially those with a strenuous workload such as reducing the need to sleep. Is their another reason you stopped such as how it affects the brain's A1?

I think this article was interesting. My question is if humans never drank caffeine would the human body produce the boost in energy we get from drinking it. I wanted to know this because if humans weren't dependent on caffeine i feel the body could produce enough energy to get them through the day.
