Ciberial Muscle 9 (CM9) Electrophysiological Recordings in Adult Drosophila melanogaster

[Abstract]  The complexity surrounding presynaptic recordings in mammals is a significant barrier to the study of presynaptic mechanisms during neurotransmission in the mammalian central nervous system (CNS). Here we describe an adult fly neuromuscular junction (NMJ), the ciberial muscle 9 (CM9) NMJ, which allows for the recording of both evoked (EPSPs) and spontaneous postsynaptic excitatory potentials (mEPSPs) at a mature glutamatergic synapse. Combined with CM9-specific genetic technologies, the CM9 NMJ ...

Optogenetic Stimulation and Recording of Primary Cultured Neurons with Spatiotemporal Control

[Abstract]  We studied a network of cortical neurons in culture and developed an innovative optical device to stimulate optogenetically a large neuronal population with both spatial and temporal precision. We first describe how to culture primary neurons expressing channelrhodopsin. We then detail the optogenetic setup based on the workings of a fast Digital Light Processing (DLP) projector. The setup is able to stimulate tens to hundreds neurons with independent trains of light pulses that evoked action ...

Functional Analysis of Connexin Channels in Cultured Cells by Neurobiotin Injection and Visualization
Author:
Date:
2017-06-05
[Abstract]  Functional gap junction channels between neighboring cells can be assessed by microinjection of low molecular weight tracer substances into cultured cells. The extent of direct intercellular communication can be precisely quantified by this method. This protocol describes the iontophoretic injection and visualisation of Neurobiotin into cultured cells.
