Neurotransmitter Systems: Synthesis, Release, Reuptake, and Network Balance

Abstract

A clinician-facing synthesis of how transmitter synthesis, vesicle cycling, calcium-triggered release, receptor engagement, clearance, and homeostatic plasticity shape neural communication. It explains why network state is not reducible to a single chemical measurement and separates core synaptic physiology from disease-level inference.
