Abstract

Electrophysiological studies of synaptic function do not robustly report release of neuropeptides and neurotrophins. These limitations have been overcome with the presynaptic expression of optical release reporters based on green fluorescent protein and fluorogen-activating protein. Here we describe how to image neuropeptide release in Drosophila at the neuromuscular junction and in the adult brain.
