Quizplus · Accepted Answer

GABA (gamma-aminobutyric acid) helps regulate neuronal activity by inhibiting signals between neurons. Studies have shown that GABA levels decrease with age, which can lead to impairments in cognitive function and memory. Serotonin, dopamine, and noradrenaline are involved in mood regulation, reward processing, and arousal, respectively, but their decline with aging is less established compared to GABA.
