Abstract:
This paper reports the effect of sodium selenite on dorsal root potentials(DR-DRP; VR-DRP)in the isolated toad spinal cord. The results indicate that selenite has a double phase effect or dorsal root potentials, that is, increasing the amplitude first, and then decreasing it. Using sucrose gap technique, we have proved that selenite has a dcoplarization effect on the dorsal roots. Further experiments indicate that spontaneous dorsal root potentials induced by selenite are attributed to its actions on the interneurons activities of the spinal cord. In addition, the mechanism of selenite's effects was discussed.
