A Review on Optogenetics and Its Applications in Addiction Research

Writer: David James Estrin

Optogenetics is a current tool used across disciplines to control membrane potential in genetically altered cells in vivo and in vitro. Dr. Gero Miesnböck introduced transgene expression in genetically modified mouse neurons to produce Channelrhodopsin-2 (ChR2) to control membrane potential via photostimulation, a procedure he later coined "optogenetics" (Zemelman et al., 2002; Lima & Miesenböck, 2005; Miesenböck & Kevrekidis, 2005; Miesenböck, 2009). By genetically modifying an animal's genome, scientists are able to photo-stimulate action potentials (APs) in distinct neurons subpopulations thus controlling the neuron's function.
