Rohon–Beard cell
Rohon-Beard cells are specialized neurons with mechanoreceptive properties. They occur during the embryonic stage of development and are found in the dorsal part of the spinal cord in fish and amphibians.[2]
Rohon-Beard neurons develop on the border between the ectoderm epidermal (surface) and neuroectoderm, first in the order of receptor neurons.[3]
In most species Rohon-Beard cells disappear during the course of ontogenetic development (e.g. in zebrafish during the first two days of development, at the larval to be, replaced by a dorsal root ganglion of spinal nerves)[4] by apoptosis.[5]
John Beard and Joseph Victor Rohon first described these cells, independently of each other.
