Description:
In the lateral edge of the "white matter" in the lamprey spinal cord, there is a group of nerve cells referred to as edge cells. The results of a combined physiological, light microscopical, and electron microscopical study suggest that these cells serve as intraspinal mechanoreceptors. Edge cells are depolarized on stretch of the lateral margin of the spinal cord, and they have nestlike ramifications in this region oriented in a rostrocaudal plane. These cells exhibit a close structural similarity with the crayfish stretch receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grillner, S -- Williams, T -- Lagerback, P A -- New York, N.Y. -- Science. 1984 Feb 3;223(4635):500-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6691161" target="_blank"〉PubMed〈/a〉
