Nature and the time course of the effect of CO2 on electroretinogram (ERG) in an arachnid.
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.
