Spectral sensitivity of the visual cells in the compound eye of the cockroach blatta orientalis


Neirofiziologiya 17(1): 57-61
Spectral sensitivity of the visual cells in the compound eye of the cockroach blatta orientalis
Intracellular recordings were made from single photoreceptors of the frontal part in the compound eye of the cockroach B. orientalis. Two spectral types of cells were revealed: UV-receptors with .lambda.max = 361 .+-. 8 nm and green-receptors with .lambda.max = 503 .+-. 12 nm. Spectral curve of the whole eye measured by ERG [electroretinography] had 2 peaks (at .lambda.maX = 350 = 370 and 500 nm) and minimum in the range of 400-430 nm. The finding was interpreted as an additional evidence for dichromatic vision of the cockroach.
