This overview explores how various hormones and neurotransmitters influence behavior, mood, memory, sexual arousal, and mental health. Key neurotransmitters like acetylcholine are significant for muscle contraction and memory development in the hippocampus. Dopamine enhances voluntary movement and pleasure, while norepinephrine is essential for arousal and alertness, stimulating the sympathetic nervous system. Additionally, serotonin plays a critical role in regulating sleep, arousal levels, and emotional balance. Understanding these interactions is vital for insights into mental health and behavioral science.
