RESUMO

1. Electrical coupling of Rohon-Beard neurones in the spinal cord of Xenopus laevis has been studied from the time of closure of the neural tube (stage 20, 22h after fertilization of the egg) to the free swimming tadpole (stage 49, 12d old). Pairs of cells were examined by impaling both simultaneously with single micro-electrodes having current-passing and voltage-recording capabilities.
