Optogenetics System

Optogenetics is an emerging experimental technology that uses optical principles and genetic engineering to make specific cell groups express or lack a certain function. It has two unique characteristics: high spatial and temporal resolution and cell type specificity. Using genetic methods to express light-sensitive channel proteins in specific cell populations, these light-sensitive channel proteins will open under specific wavelengths of light to pump protons out of the cell, or anions (such as Cl-), cations (such as Na + and K +) Pumped into the cell to hyperpolarize or depolarize the cell, so that the cell can be inhibited or excited instantly.
