Anatomical and functional connections between trigeminal sensory neurons and Mauthner cells in zebrafish larvae. (a) Dorsal view of the head region of Tg[vglut2a:Gal4FF]; Tg[UAS:EGFP] fish at 48 hpf. The dashed rectangle indicates the area corresponding to the brainstem region analyzed in (b). (b) Left panel: Kaede expressed in the trigeminal sensory neurons is photoconverted by illuminating the trigeminal ganglion region (Trg, arrow) with a laser light with a 405 nm wavelength (magenta). Afferent axons are projected towards a Mauthner cell (arrowhead) highlighted in magenta. Right panels: A single confocal section of the contact site (double arrowheads) of the afferent axons of trigeminal sensory neurons and Mauthner cells. (c) Calcium imaging of the Mauthner cells before and after tactile stimulation. (d) ∆F/F of the neural response of Mauthner cells in (c). Scale bars indicate 50 μm (c) or 20 μm (a, b).
