Fig. 2.7. Neuropil in layer 4 of area 46 from a 25 year old monkey. An example of a situation in which the outer laminae of the sheath of a myelinated axon (axon) are bulging into a dendrite. Other dendrites (dendrites 1-4) also have fragments of myelin sheaths in their cytoplasm, although in these cases the myelinated axons are not apparent.
