Caffeine blocks an inhibitory neurotransmitter called adenosine, which improves the neuron’s ability to release signals, and raises the concentration of neurotransmitters such as:

Norepinephrine, a hormone secreted by the adrenal gland, stimulates nerve cells.
Dopamine is a chemical that interacts in the brain and affects many sensations and behaviors including attention, direction and body movement (2).
Dozens of studies have spoken of the benefits of caffeine as a brain function enhancer, including: (3)

Memory booster
Improve mood
Reinforcement of reaction
Vigilance
Improve attention.
The benefits of green tea to improve brain function are not only dependent on caffeine. Rather, it contains an additional element, an amino acid called “L-theanine”, which is able to cross the blood-brain barrier. It is a barrier between the blood and extracellular means of the brain (4).

“L-theanine” increases mental focus, improves sleep, relaxation, anti-anxiety, increases cognitive performance, produces alpha waves in the brain, boosts the immune system, and lowers blood pressure (5, 6, 7)

Because of the sufficient caffeine and “L-theanine” that green tea gives to the body, many talk about how long the feeling of high energy when drinking green tea compared to drinking coffee.
