Code TH H2.00.06.2.02005

In neuroanatomy, a neuropil, which is sometimes referred to as a neuropile, is a region between neuronal cell bodies in the gray matter of the brain and blood-brain barrier (i.e. the central nervous system). It consists of a dense tangle of axon terminals, dendrites and glial cell processes. It is where synaptic connections are formed between branches of axons and dendrites.[1]

White matter, which is mostly composed of axons and glial cells, is generally not considered to be a part of the neuropil.[citation needed]

Etymology

From the Greek: neuro and pilus, meaning felt.[2]
