Optogenetic Control of Human Stem Cell-Derived Neurons

Abstract

Spontaneous and optogenetically evoked activities of human induced pluripotent stem cell (hiPSC)-derived neurons can be assessed by patch clamp and multi-electrode array (MEA) electrophysiology. Optogenetic activation of these human neurons facilitates the characterization of their functional properties at the single neuron and circuit level. Here we showcase the preparation of hiPSC-derived neurons expressing optogenetic actuators, in vitro optogenetic stimulation and simultaneous functional recordings using patch clamp and MEA electrophysiology.
