Genetically encoded voltage indicator
open-in-new
<p>Genetically encoded voltage indicator (or GEVI) is a <a href="/facts/Protein/Jxmagu3E">protein</a> that can sense <a href="/facts/Membrane_potential/DpNG14c7">membrane potential</a> in a cell and relate the change in <a href="/facts/Voltage/EN2po6N2">voltage</a> to a form of output, often <a href="/facts/Fluorescence/qsJVT2qP">fluorescent level</a>. It is a promising <a href="/facts/Optogenetics/RbYYcrr2">optogenetic</a> recording tool that enables recording of <a href="/facts/Electrophysiology/VPd5VYzm">electrophysiological</a> signals from cultured cells and live animals. Examples of GEVI families include Quasar/Archon, Ace-mNeon,, and ASAP. </p>
