Lights And Larvae: Using Optogenetics To Teach Recombinant Dna And Neurobiology, John Titlow, Heidi Anderson, Robin L. Cooper

Biology Faculty Publications

Switching genes between organisms and controlling an animal’s brain using lasers may seem like science fiction, but with advancements in a technique called optogenetics, such experiments are now common in neuroscience research. Optogenetics combines recombinant DNA technology with a controlled light source to help researchers address biomedical questions in the life sciences. The technique has gained the most traction in neurobiology—the biology of the nervous system—where specific wavelengths of light are used to control or measure the activity of neurons in transgenic organisms (i.e., those with artificially inserted genes).

These optical recording and stimulation techniques are used in nervous system …
