Optical molecular and cellular imaging has provided considerable information in various life science research fields. In particular, pHluorin-based assays allow us to specifically investigate presynaptic physiological processes, such as synaptic transmission and synaptic retrieval. Here, I describe quantitative synaptic transmission in primary cultured hippocampal neurons using a vGlut-pHluorin system combined with a high-fidelity optical imaging system and its regulation by inositol pyrophosphate.

Key words
