(a) A schematic illustrating the location of sensory neuron cell bodies.
(b) Two groups of sensory neurons are required for mediating anterior harsh touch response. The anterior gentle touch sensory neurons ALM and AVM were killed in all ablations. *p<0.03. **p<0.0001 (ANOVA with Bonferroni test compared to control). n≥9. Error bars: SEM.
(c) PVD and PDE together are required for mediating posterior harsh touch response. The posterior gentle touch sensory neuron PLM was killed in all ablations. V5 is the precursor cell of PVD and PDE. **p<0.0001 (ANOVA with Bonferroni test compared to control). n≥7. Error bars: SEM.
(d) PHA/PHB are important for mediating anus harsh touch response. PLM was killed in all ablations. **p<0.0001 (ANOVA with Bonferroni test compared to control). n≥9. Error bars: SEM.
