Figure 6. Differential expression of serotonin receptors in locomotor circuit components.

Figure 6.

A-E. Maximum intensity projections show Gal4-driven expression of serotonin receptors in both the brain (A-E) and VNC (A’-E’). All scale bars are 50 μm.

F. Schematic of sensory and motor neuron populations in an adult leg.

G-K. Maximum intensity projections show Gal4-driven expression of serotonin receptors in neuronal processes in the adult leg. Each receptor is expressed in a distinct pattern in sensory-motor components. While some are expressed in motor neurons (purple arrows, hatched arrows indicate limited or weak expression) and proprioceptive neurons (green arrows), others are not. All receptors are expressed in a subset of mechanosensory neurons (orange arrows), but some are preferentially expressed in proximal or distal leg segments. All scale bars are 50 μm.
