INTRARETINAL ABGELEITETE ERG-KOMPONENTEN DER ISOLIERTEN KANINCHENNETZHAUT

Using micropipettes the components PII and PIII of the ERG were separated in the ERG of the isolated rabbit retina, the component PI was missed. The best differentiation of PII and PIII was possible in a depth corresponding to 57 per cent of the whole thickness of the retina measured from the receptor-side and 43 per cent from the ganglion-cell-side respectively. This depth corresponds histologically to the distal parts of the inner nuclear layer. Here the influence of increasing light intensity was studied on the isolated PII and PIII. There are some reasons to suspect that PIII consists of two subcomponents like the PIII of cold blooded vertebrates. © 1968.
