neuropil

 [noor´ro-pil]
a dense feltwork of interwoven cytoplasmic processes of nerve cells (dendrites and axons) and of neuroglial cells in the central nervous system and some parts of the peripheral nervous system.

neu·ro·pil

, neuropile (nū'rō-pil, -pīl),
The complex, feltlike net of axonal, dendritic, and glial arborizations; forms the bulk of the central nervous system's gray matter, and in which the nerve cell bodies lie embedded.
