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


, : Spectral sensitivity of the visual cells in the compound eye of the cockroach blatta orientalis. Neirofiziologiya 17(1): 57-61

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.

Some small median neurosecretory cells of the brain are recruited from the lateral globuli cells. This recruitment helps to maintain the number of neurosecretory cells in the brain of Blatta orientalis L. during post-embryonic development.
