Figure 6.

A, light responses of a BHC to stimuli of three intensities and six wavelengths. Short and middle wavelength stimuli evoked hyperpolarizing responses, whereas long wavelength stimuli induced depolarizing responses. The timing of the stimuli and scale of the responses are shown in the figure. B, light responses of a BHC to 600, 650 and 700 nm full-field light stimuli compared to 500 nm wavelength-induced light responses of the same BHC. The responses are scaled and inverted such that the light responses overlap the 500 nm light responses (grey traces). The timing of the stimulus is indicated in the figure. C, redrawing of the light onset responses shown in B on an expanded time scale.
