Laser stimulation of nerve cells in Aplysia

Science. 1971 Mar 5;171(3974):907-8. doi: 10.1126/science.171.3974.907.


Laser radiation at 488 nanometers selectively stimulates neurons in the abdominal ganglion of the marine mollusk Aplysia californica. The laser radiation can be scanned over the surface of the ganglion and can be effectively utilized in mapping cellular interconnections. The laser appears to cause these changes through some mechanism other than damage.
