Yes, caffeine effects the brain by increasing the neuron firing. Caffeine also speeds up other things like your heart rate.

Thanks for the feedback!
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.
The consumption of excessive caffeine can cause harmful effects in the human body. It can cause anxiety due to increase in heart rate. Additionally, caffeine can produce heada…ches, caused by the restriction of the blood vessels and can increase the risk of stroke. Caffeine is a stimulant and can cause an increase in heart rate. Furthermore, it increases risk of irregular heart rhythm.
Caffeine is a stimulant, and therefore makes the processes in you brain work faster.

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 inhibits ADH causing the levels in the body to lower. Anti-Diuretic Hormone is released when the body wishes to conserve water. The hormone tells the kidneys to reab…sorb more water which results in urine becoming concentrated. Alcohol has a similar effect which is why, when it inhibits ADH, the body no longer attempts to conserve water. This results in frequent urination which eventually becomes clear as less waste has accumulated in the urine. The following morning after heavy drinking, the body is dehydrated resulting in concentrated urine. Coffee and caffeinated beverages are the worst hangover cures for this reason and will only starve the body of water further - resulting in a prolonged hangover!
Well I mixed them this morning and I've been tired, had nausea, had virtigo, lots of dizziness. Also my eyes couldn't focus on things.
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 not bad for your brain , but can be bad for other parts of your body.
