Key steps is neurotransmitter dynamics include:
- Sindrom 1st; FLT: 0 AFL3; Synthesis and packaging 1; FLT: 1 1f 3; --Preissors are converted ino neurotransmitters and stored is synsicles.
- Pertama; FLT: 0 = 33; Exocytosis = = 1; FLT: 1 = 1 = FLT: - Action potentials trigger vesicle fusion and inte the synxft.
