Abstract

Recent behavioural experiments dealing with the mechanism of polarized skylight navigation in bees indicated that processing of e-vector information in the visual system involves antagonistic interaction between polarization-sensitive photoreceptors1,2. Here we report electrophysiological recordings from polarization-opponent interneurons in the optic lobe of crickets. These neurons receive antagonistic input from polarization sensitive photoreceptors with orthogonally arranged analyser orientations. Although polarization-sensitive interneurons have previously been reported from the visual system of crabs3 and goldfish4,5, this is the first demonstration of polarization-opponent units.
