Caffeine is a central nervous system stimulant that reduces fatigue and drowsiness. At normal doses, caffeine has variable effects on learning and memory, but it generally improves reaction time, wakefulness, concentration, and motor coordination.
One of the important effects caffeine has on neurotransmission is to stimulate cells to release calcium, according to a study reported in the 2008 PLoS One.. Calcium, in turn, acts as a signal that enables nerves to release the neurotransmitters that they use to relay messages to other cells.dditionally, the study cites an association between caffeine and decreased risk of Parkinson's disease via a neuroprotective effect of caffeine on neurons involved in transmission of dopamine, the main neurotransmitter affected by the striatum. .
