Strothjohann, "Abnormally phosphorylated tau protein related to the formation of neurofibrillary tangles and neuropil
threads in the cerebral cortex of sheep and goat," Neuroscience Letters, vol.
Cerebellum showed marked distribution and atrophy of neuropil
architecture (Figure 10).
Neuropathological features of TME include spongiform degeneration in the neuropil
of the brain, astrocytosis and the formation of PrP deposits of the TME agent.
This space (the neuropil
) represents 90-98% of the volume of the human cerebral cortex, with an estimated 1bn synapses per cubic nanometer of neuropil
Eight different types of dopaminergic neurons innervate the Drosophila mushroom body neuropil
: anatomical and physiological heterogeneity.
The other types of cells in leech ganglia are two connective glial cells that surround the axons, a neuropil
giant glial cell and six packet-glial cells that ensheathe the cell bodies of neurons.
The abnormal translocation of tau from axonal microtubules to neuropil
thread inclusions, cell bodies and dendritic processes, where tau aggregates and accumulates, are pther prominent cytopathological hallmarks observed within AD brain sections .
Primitive neuroectodermal tumours are members of the Ewing's sarcoma family composed of small round cells normally lacking morphologic evidence of neuroblastic differentiation in the form of neuropil
or ganglion cell formation.
The antiserum stained neuropil
, neuronal cell bodies, and periganglionic tissues.
The reduction in hippocampal volume is attributable to decreased neurogenesis, death or atrophy of existing neurons, changes in neuropil
, the number of synapses, and synaptic bulk (Sapolsky 2000; Kempermann 2001).
Survey of cerebellum white matter in the treatment group compared with normal cerebellum white matter tissue in control group demonstrated defects in the neuropil
tissue which was accompanied by decreased staining and increased interstitial space and decreased neuroglia cell condensation.
Learning a new skill such as playing a musical instrument, learning to type, or reading Braille requires extensive practice, and this practice is likely instrumental in changing the neuropil
in relevant brain regions (Kolb & Whishaw 1998).
