Supplementary Figure 2: BarESR1 and BarCRH projections to urinary nuclei in the spinal cord.
From: Voluntary urination control by brainstem neurons that relax the urethral sphincter

a, Schematic for testing Bar cell type axonal projections to spinal cord. b, Representative BarCRH axon projections at the L1/L4/L6/S2 spinal cord levels, separate from example in Fig. 1g-i. Top is ArchT virus, bottom is ChR2 virus. c, Same as (b), but for BarESR1 axon projections. Scale bars = 100 μm.
