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.
