Fig. 4. Effects of lack of optic photoreceptors on the LOn response. The LOn shift
paradigm was used to test the CS (Canton-S, control; A–D), the
oc1 ocelliless (E–H) and the
clieya-2 eyeless strains (I–L). Legends are as
described for Fig. 3 except
that, for oc1 and clieya-2, some
collection bins were greater than 10 min intervals but were averaged in 10 min
intervals as indicated by stippling.
