Schematic overview of the lateral line in zebrafish. (A) Location of the neuromasts in a zebrafish larva at 5 days post fertilisation (dpf). Indicated are the neuromasts identified in Tg(HGn39D), the anterior and posterior sensory ganglia and the projections they send to the neuromasts and into the brain. (B) Dorsal view of the head of a 5 dpf zebrafish larva. Indicated are the sensory ganglia and their projections (cyan) as well as the REN and CEN in the rhombencephalon (magenta), where we find the inhibitory efferent cells projecting to the lateral line. (C) Overview of the different cells in the REN and CEN (magenta). The REN contains a single cell type, which sends a projection anteriorly that turns toward the ALL ganglion. The CEN contains two cell types; ROLE, which projects past and follow the projection path of the REN cell; and a RELL cell, which projects till the REN cell, where it turns toward the PLL ganglion. ALL, anterior lateral line; PLL, posterior lateral line; REN, the rostral efferent nucleus; CEN, the caudal efferent nucleus nucleus; ROLE, the rhombencephalic octavolateral efferent neuron; RELL, the rhombencephalic efferent neuron to the lateral line.
