How does caffeine affect neurons in the brain?

Adenosine receptors stick through the neuron membrane, so that partof them are on the inside and part is on the outside of the cell.Now, when adenosine, a natural chemical in …the body, attaches tothe adenosine receptor it shifts the shape of the receptor, thisshift reaches all the way to the part on the inside of the cell,and causes the receptor to release attached molecules calledG-proteins. These g-proteins now float around the inside of thecell and have all sorts of effects, in this case, to inhibit theneuron. Caffeine also binds to the adenosine receptor, but itdoesn't activate the receptor. This means that the receptor istotally shut down, and can't work to inhibit the neuron any more.The end effect is to allow the neuron to be more active than it wasbefore the caffeine.
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 kill brain… cells? No. Even very high amounts would not.
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.
i dont know hahahahhahahhahahahah
Yes, caffeine effects the brain by increasing the neuron firing.Caffeine also speeds up other things like your heart rate.
in japan and china with the chinks
it wakes you up
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...)

Yes caffeine does affect you. Caffeine is a drug and is a very common drug in the United States. To simplify what it does to you, it messes with your brain and keeps you alert…( that's why most people drink coffee in the morning, to wake up)
It causes the adrenal glands to produce adrenaline. This release ofadrenaline causes a faster heart rate, opening up of breathingtubes, release of sugar into the bloodstream f…rom the liver,tightening of muscles, an increase in blood flow to muscles. Othereffects include an increase in dopamine levels.
I'm sure there in the cerebral cortex which is at the very top of your brain
Caffeine is not bad for your brain , but can be bad for other parts of your body.
The brain has two kinds of cells, neurons and glial cells. So if the brain did not have neurons it could still have glial cells, but they have no function in the absence of ne…urons. You would, in effect, have converted the brain into a tumor. Human beings cannot live without a brain. (Nor any irrational animals) . We wouldn't be animals, we would be stupid zombies.
If too much caffeine is in your system, there can be a temporaryimpulse on the other neurons. This sudden impulse will momentarilywake up your brain but will damage some neuro…ns. The neurons mayget aggravated and cause them to shake violently. This frictioncould cause the neurons to join together with another neuron whichwould cause an oxypartifamine reaction. That means that the neuronwill merge and could cause serious brain problems. If experiencingbrain problems, one should immedietely consult a doctor for furtheradvice. DO NOT WASTE TIME GO SEE A DOCTOR
