Figure 5. TRPM8 axons terminate in simple, ramifying, and complexed branches. A: Wholemount of TRPM8^EGFP mouse cornea central-pericentral region. B–D: Terminal morphology; the small panels under each image show orthogonal views generated by projecting the z-series above it in the x-plane. Simple (B), ramifying (C), and complex (D) morphologies are demonstrated. Scale bars: (A) 20 μm; (B–D) 5 μm.
