Die Projektion der optischen Umwelt auf das Raster der Rhabdomere im Komplexauge von Musca

摘要: The dioptrics of the Musca ommatidium acts as an inverting lens system. distal endings rhabdomeres at basis dioptric apparatus are separated and arranged in a typical asymmetric pattern. optical axes individual one geometric projections rhabdomere into environment, inverted by 180° apparatus. divergence angles between correspond to appropriate set ommatidia such way, that seven looking point environment (in intermediate region dorsal ventral part eye: eight nine ommatidia). These facts were established from sections living eyes confirmed using special methods intact animal. pattern decussation retinulacell axons retina lamina was predicted adopting hypothesis fibres retinulacells number six, whose rhabdomers project single “cartridge” lamina. connections other investigators. We have therefore correspondence lattice points “cartridges” It is shown unfused rhabdomeric structure increases effective entrance pupil eye factor (resp. eye) compared classical apposition eye. —The compound can be regarded “neural superposition eye”.
