They also undergo solution as a result of injury to the axon evenat a great distance from the cell, the so-called axon-reaction or chromatolysis(Fig. 27, B). The neurofibrils were first brought forcefully to the attention of neurologistsby Bethe (1903). These are delicate threads which run through the cytoplasmin every direction and extend into the axon and dendrites (Fig. 28). Theappearance of the fibrillae differs according to the technic employed in preparingthe tissue for microscopic examination. While in the preparations by Bethesmethod the fibrils do not appear to branch or anastomose with each o
