Reticulospinal neuron

Confocal micrograph of a transverse section of the brain of a zebrafish embryo, at the level of the hindbrain. The brain section was stained using an antibody that marks a calcium binding protein (calretinin). The image shows a big reticulospinal neuron and its processes, surrounded by other smaller neurons. Reticulospinal neurons are specific neurons found in the brains of fish that are thought to be involved in coordinating swimming.
