Web6 jul. 2016 · We find that an unexpectedly large proportion of myelinated axons in cortex arise from a specific subtype of inhibitory neuron: the parvalbumin-positive (PV+) basket cell. These PV+ axons are especially prominent in the middle cortical layers. Web11 okt. 2024 · Oligodendrocytes (or oligodendroglia) are star-shaped neuroglia that form the myelin sheaths on axons of the central nervous system. A single oligodendrocyte has about 15 flat, broad, arm-like processes coming out of the cell body. With these they can myelinate multiple axons by spiraling around them to form a myelin sheath.
