Optogenetics — the might of light
WebJan 7, 2024 · Optogenetics is a method for controlling a neuron’s activity using light and genetic engineering. Most all cells in the body maintain a charge gradient (an imbalance in the concentration of positively and negatively charged ions) across their cell membranes. This gradient creates a polarized electric potential, or voltage. WebApr 1, 2024 · In the 1980s, Nobel laureate Francis Crick suggested that light might have the right stuff for controlling neurons of different types, thanks to its ability to provide timed pulses with millisecond temporal precision. However, light penetrates only a few hundred microns into the surface of the brain, scattering without affecting signaling.
