Figure 2. C1V1-ET/ET and ChR2-HR evoke wavelength-dependent activity in mechanosensory neurons. A).

Figure 2

The six gentle touch mechanoreceptor neurons, their localization and morphology are shown. B) The effectiveness of C1V1-ET/ET and ChR2-HR, expressed in different strains, in evoking behavioral responses in mechanoreceptor neurons (backward escape, reversals) were compared, in response to 400 and 568 nm light of different intensities, as indicated. While C1V1-ET/ET can be specifically activated without co-activation of ChR2-HR at 568 nm, significant co-activation of C1V1-ET/ET at 400 nm is apparent. Displayed is the mean probability of backing in response to blue light stimuli (and s.e.m.), as described in Methods. Number of animals is indicated, and statistically significant differences were determined by two-tailed Student’s t-test, as indicated (***p<0.001).
