Neurotransmitters: The Brain’s Chemical Messengers is your essential guide to the chemicals that power thoughts, emotions, memory, and behavior. It explains how major neurotransmitters—such as dopamine, serotonin, norepinephrine, GABA, glutamate, and acetylcholine—regulate mood, motivation, learning, and sleep. The guide shows how imbalances in these messengers can contribute to mental health conditions like depression, anxiety, ADHD, and schizophrenia.
It also explores how medications such as antidepressants, antipsychotics, mood stabilizers, and sleep aids target these systems to restore balance. Special sections highlight the role of excitatory vs. inhibitory transmitters, as well as how diet, stress, and lifestyle can influence brain chemistry. Designed as a visual and practical reference, this resource helps students, patients, and clinicians understand the brain at a chemical level and how it connects to mental wellness.
