Principles of Optogenetic Methods and Their Application to Cardiac Experimental Systems.

Front Physiol 2019

Ferenczi EA, Tan X, Huang CL

Abstract

Optogenetic techniques permit studies of excitable tissue through genetically expressed light-gated microbial channels or pumps permitting transmembrane ion movement. Light activation of these proteins modulates cellular excitability with millisecond precision. This review summarizes optogenetic approaches, using examples from neurobiological applications, and then explores their application in cardiac electrophysiology. We review the
