A dense network of tiny nerve branches in the brain and spinal cord where neurons connect
  • noun
  • /ˈnjʊəroʊˌpɪl/
  • Specialized
: neuropilo
  • In the human brain, the neuropil densely packs unmyelinated nerve fibers, crucial for processing information.
  • excitatory neuropil
  • inhibitory neuropil
  • neuropil activity

Examples

  • This technique identifies all deposits of beta-amyloid within the neuropil, not just those plaques greater than 30 µm in diameter.

    Academic text (1995)
  • Our results suggest that the overall area of beta-amyloid positive plaques and neuropil deposits may contribute to the cognitive dysfunction in Alzheimer's disease.

    Academic text (1995)
  • Numerous large-scale plaques are present, as well as neuropil deposits of varying size.

    Academic text (1995)
  • This technique also allows for the detection of smaller neuropil deposits of beta-amyloid that could not be counted manually.

    Academic text (1995)
  • Here we find that goal-directed behavior produces broadly distributed task-related activity throughout the neocortex, reflected both in widespread single-cell and in neuropil activity.

    Academic text (2016)
  • A small focus of a neuropil-like structure with rare glial cells and corpora amylacea was located adjacent to the skeletal muscle (Figure 2, C).

    Academic text (2004)
  • Together, these data supported the hypothesis that ALM-mediated initiation of goal-directed licking behavior is necessary for the elicitation of cortex-wide activity in superficial neuropil.

    Academic text (2016)
  • This difference revealed that the conjunction of licking behavior in the setting of immediate or anticipated reward, but not licking in itself, produced the observed globally distributed neuropil activity dynamics. # Cell-Type-Specific Interneuron Activity Dynamics #

    Academic text (2016)
  • Measuring both these signals in superficial neuropil throughout the cortex using wide-field microscopy is therefore important to test theories of the widespread broadcast of task-related information during goal-directed behavior.

    Academic text (2016)
  • Research shows that increased neuropil in specific brain regions is linked to enhanced cognitive abilities.

Morphology

neuropil = neuro + pil

The word is a technical coinage built with the combining form neuro- and a rare bound element pil-, but the second element is not a familiar English word, so the meaning is not predictable for most learners.

Etymology

Neuropil combines neuro-, the same root as neuron, meaning 'nerve', and -pil, a part that suggests a 'dense mass' or 'felt' of tiny threads, so think of it as a 'felt' of nerve threads, which matches its meaning as a dense network in the brain.
