If you were to take a culture of brain cells on a petri dish and submerge them in a caffeine solution, it probably would. But in people, is drinking coffee going to kil…l brain cells? No. Even very high amounts would not.
caffeine is a psychoactive drug that is considered a stimulant. you will experience heightened awareness and the jitters. It can also cause large amounts of urination
Caffeine is a stimulant drug, which speeds up the synaptic connections in your brain, increasing reaction times. Nicotine, and Ecstasy do similar things, but are much more da…ngerous, and (in the case of ecstasy) illegal in most countries.
Caffeine while soluble in water also passes through the blood-brain barrier.
Caffeine is a stimulant, and therefore makes the processes in you brain work faster.
Caffeinated drinks are not good for the body. They can wreak havoc on the bladder and kidneys, causing infections and intense pain. They should be consumed as sparingly as… possible.

Suggestion: K-Wolf Try looking here http:/www.coolquiz.comtrivia/explain/docscaffeine.asp After reading that I've decided to cut back on caffeine a little..., maybe.…... If you're looking for a short answer: K-Wolf Caffeine is a mild and legal addictive stimulant, it has the same cause and effect as most illegal drugs such as cocaine and heroine. You'll find everything you need to know about it on the link above. Now it is time for me to go get some more Coca.....cola...... ( you do know Coke still has trace amounts of cocaine in it..., maybe combined with caffeine is the reason everyone want to buy the world a Coke...)
It causes the adrenal glands to produce adrenaline. This release of adrenaline causes a faster heart rate, opening up of breathing tubes, release of sugar into the bloodst…ream from the liver, tightening of muscles, an increase in blood flow to muscles. Other effects include an increase in dopamine levels.
Caffeine is harm full in one way but also not in another. This is because caffeine can provide energy throughout the day, coffee is one of the main drinks that have caffeine i…n them. coke also provides caffeine in the body and that is why people get hyperactive when drinking them. If you abuse on caffeine such as coffee and coke people can become to energetic causing the body to become energetic and that is not good for the body because we humans don't need so much energy we need the right amount. Think about it as an overload of too much energy just like a computer when too much information is stored in one folder there's too much of it so it needs to get rid of some stuff. Mainly when the body has too much caffeine it will stay awake all day and night depending on how much is in your body, that is why some people say to never drink coffee or coke before going to bed! For healthy adults at low dosages, no. Those who have heart problems, are pregnant, etc. should not take caffeine.
There are obvious negative effects of sugar, but really only on the heart. Your brain on sugar is much more hyper active. Your neurons fire faster, and cause messages to be se…nt quicker. The reason there is a crash after eating a lot of sugar is because of a waste product of your neurons firing. The waste product is called Adenosine. Caffeine works by inhibiting Adenosine receptors which cause you to sleep. If you take sugar and caffeine together, you get hyper, with a slower crash rate than if you just had sugar. You can find out more about all of these things (sugar, caffeine, and adenosine) on sites like wikipedia, or more trustworthy sites...
caffeine is actually a drug. if you have too much, you could get addicted. once you get addicted and drink/eat too much of it, you get very hyper. therefore, you could have a …heart attack, spasm or heart/kidney problems.
