ScerGAL4stum.PD drives expression in proprioceptive neurons.
ScerGAL4stum.PD drives expression in three neurons of the mesothoracic leg, one at the femur-tibia joint, one at the tibia-tarsus joint, and the third spanning the second tarsal segment. The cell bodies of labeled neurons are positioned at the distal end of each leg segment, and their dentrites terminate at the corresponding joint. The axons terminate within the ventral nerve cord and form round arborization patterns.
