Abstract
A VARIETY of electrical events can be demonstrated in the nerve cord and myotomes of amphioxus by conventional electrophysiological methods, following electrical, mechanical or photic stimulation. Fine silver wire electrodes (20–30µ) or tungsten micro-electrodes (2.0–0.5µ) proved more satisfactory than glass capillaries. Recordings were made from the intact animal, from preparations stripped off muscles and from isolated nerve cords. Further details of the experimental procedure will be published elsewhere.
