neuropile
Noun: 1. The complex network of unmyelinated axons, dendrites, and glial branches: This refers to the dense, intricate web of neural processes (the parts of neurons that send and receive signals) and supportive glial cell extensions. This network forms the primary substance of the grey matter in the central nervous system (the brain and spinal cord), where the cell bodies of neurons are located.
The term neuropile is used in neuroscience and anatomy to describe the specific structural composition of neural tissue. It emphasizes the interconnected, synaptic region where communication between neurons primarily occurs, as opposed to the areas dominated by neuronal cell bodies or myelinated (insulated) nerve fibers.
- Under the microscope, the neuropile appears as a dense, tangled matrix of fine neural processes.
- Synaptic connections are abundant within the neuropile of the cerebral cortex.
- The study focused on how signals are processed within the olfactory neuropile.
- Neuropil is a common alternate spelling. Both "neuropile" and "neuropil" are accepted and refer to the same structure.
- In research, specific regions may be referred to by their function, e.g., or , indicating areas where processing for those functions is concentrated.
- Neuropil (n.): A variant spelling of neuropile.
- Grey matter / Gray matter (n.): The region of the central nervous system consisting mainly of neuronal cell bodies, dendrites, and unmyelinated axons, within which the neuropile is the predominant component.
- Synaptic neuropil (n.): A term sometimes used to highlight the region rich in synapses.
- Neural plexus (less common, more general)
- Neuropil matrix
- White matter: Refers to areas of the central nervous system rich in myelinated axons, which appear white and form the nerve tracts, in contrast to the grey matter where neuropile is found.
- Nucleus (in neuroanatomy): A cluster of neuronal cell bodies within the central nervous system, which is embedded within the neuropile.
-
the complex network of unmyelinated axones, dendrites, and glial branches that form the bulk of the central nervous system's grey matter and in which nerve cell bodies are embedded
