Serotonin, often referred to as the "happy molecule," plays a pivotal role in regulating mood, cognition, appetite, and various physiological functions. Central to this regulatory process are serotonin receptors, which act as molecular switches, mediating the effects of serotonin within the brain and throughout the body. However, disruptions in serotonin signaling can lead to a myriad of mental health disorders, emphasizing the critical need for innovative interventions to restore balance.
