Electroantennograms (EAGs) and electroretinograms (ERGs) in the genetic dissection of synaptic function in Drosophila melanogaster

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Electroantennograms (EAGs) and electroretinograms (ERGs) are extracuticular recording techniques that require stimulations from two distinct sensory stimuli and have been instrumental in mapping the role of seven transmembrane receptors and downstream signaling in the transduction of the sensory stimulus to synaptic signals. This review will provide an overview of the different approaches used with these two techniques and the underlying success seen in the implementation of vertebrate studies that led to translational outcomes. We will review systematically the classic approach and its modifications and emphasize how electrophysiological studies of visual and olfactory transduction provided insights that have been instrumental in discovering signaling mechanisms that are disrupted in diverse neurological states including neurodegeneration and circadian rhythms.
