Neurotranszmitteur Dynamics: Fundamentals and Regulation

Neurotranszmitters are chemicalsMessengers that transmitt signals across synapses between neurons. Their synthesis, storage, release, recepto binding, reuptake, and degradation are stringentli regulated to maintain neurad communication and homeostasis.
