Effects of X-rays on Electrical Activity in the Eye of the Cockroach Blaberus giganteus

Naturevolume 199page616 (1963) | Download Citation



SIGNIFICANT changes in electroretinograms (ERG) and in spontaneous electrical activity recorded from the compound eyes of cockroaches have been found here during investigations of the effects of radiation on insects. These electrical discharges, although similar to the activity recorded from the optic nerve of Limulus1, do not exhibit as marked a change in frequency with light stimulation. In this communication, we present the results of preliminary studies of the effects of X-rays on both the ERG and the spontaneous electrical discharges in the eye of the cockroach B. giganteus.
