Origin: Probably formed within English, by clipping or shortening. Etymon: neuropilema n.

Etymology: Probably shortened < neuropilema n. Compare German Neuropil (1899 in the passage translated in quot. 1900 at sense 2).

Anatomy and Zoology.

1. Tissue consisting of a dense network of neuronal and glial processes, forming a large part of the grey matter of the nervous system; (also) a structure or region composed of such tissue.

1894 Proc. Royal Soc. 55 409 The cell lies in the lateral mass of ganglion cells, and the fibre gives off lateral branches to the neuropile before crossing to the other side.

1899 L. F. Barker Nerv. Syst. xxiii. 271 This investigator..isolated the neuropil of the second antenna of Carcinus—in other words, he removed the ganglion cells of the neurones supplying the antenna, but left their processes and side branches.

1934 Jrnl. Compar. Neurol. 59 95 In some parts of the [amphibian] brain much branched and contorted unmyelinated axons form a dense entanglement which is termed neuropil.

1964 R. M. Fox & J. W. Fox Introd. Compar. Entomol. vi. 179 A ganglion..has a central mass of medullary tissue (neuropile) consisting of the intermixed axons and dendrons of motor and internuncial neurons and the terminal arborizations of sensory dendrons.

1974 Sci. Amer. Jan. 41/1 In addition to the major branches running through roots and connectives there are many such processes within the neuropil, the region in the center of the ganglion where synaptic connections are made.
