Caffeine primarily affects neural communication by blocking adenosine receptors in the brain. Adenosine is a neurotransmitter that promotes sleep and relaxation; by inhibiting its action, caffeine increases neuronal excitability and stimulates the release of other neurotransmitters like dopamine and norepinephrine. This leads to heightened alertness, improved mood, and enhanced cognitive function. Additionally, the increased neurotransmitter activity can enhance synaptic plasticity, impacting learning and memory processes.
