[Spectral sensitivity of the visual cells of the complex eye of Blatta orientalis].
Intracellular recordings were made from single photoreceptors of the frontal part in the compound eye of the cockroach Blatta 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 had two peaks (at lambda = 350-370 and 500 nm) and minimum in the range of 400-430 nm. The finding has been interpreted as an additional evidence for dichromatic vision of the cockroach.
