Chromatic properties of lateral inhibition in the eye of a fly

Abstract

Light-induced potentials were recorded intracellularly from the axons of the monopolar neurons L1 and L2, in the eye ofCalliphora erythrocephala. 1. The receptive fields of these secondary neurons were determined for various wavelengths of the stimulus light (Figs. 1 and 2). No differences associated with the different wavelengths were found. 2. Curves of responsevs. intensity were recorded for different wavelengths (Figs. 3 and 4). These differed only in their position along the intensity axis.
