Zusammenfassung
Physical measurements of the energy content of effective optomotor stimuli for the fly Musca support the notion that single light quanta trapped by the photopigment of the retinal receptors generate adequate sensory messages. The results of an electrophysiological experiment on single retinula cells in the fly‘s eye are presented to strengthen confidence in certain assumptions it was necessary to adopt with regard to receptor optical and spectral properties in order to calibrate the complex movement stimuli. This experiment also emphasizes the small amplitude of electrical signals generated in the receptors by dim but behaviourally effective pattern illumination levels.
