Summary

Automatic Translation

To relaterede metoder er beskrevet for at visualisere subcellulære hændelser, der kræves til synaptisk transmission. Disse protokoller muliggør realtidsovervågning af dynamikken i præsynaptisk calciumtilstrømning og synaptisk vesikelmembranfusion ved hjælp af levende cellebilleddannelse af in vitro-dyrkede neuroner.
