title: Nature and the time course of the effect of CO2 on electroretinogram (ERG) in an arachnid.
abstract: Electroretinogram recorded from the median eye of the scorpion, Heterometrus fulvipes before and after exposure to CO2 indicated that the rate of recovery of 'b' wave to pre-CO2 level was slow and delayed as compared to 'a' wave. 'b' wave may therefore have a more central origin than that of 'a' wave, which finds corroboration in the results of the depth recording in this eye with the microelectrode.
