PQR dendrite guidance defects. (A, B) Micrographs of young adult PQR neurons expressing gcy-32::gfp. Anterior is to the left, and dorsal is up. In wild type, the PQR dendrite extends directly to the posterior. In arx-7(ok118M+), the PQR dendrite extends posteriorly but has multiple turns. The scale bar in (A) represents 5 μm. (C) Quantification of PQR dendritic guidance defects.
