Tracts of lissauer
The posterolateral tract (fasciculus of Lissauer, Lissauer's tract, tract of Lissauer, dorsolateral fasciculus, dorsolateral tract, zone of Lissauer) is a small strand situated in relation to the tip of the posterior column close to the entrance of the posterior nerve roots. It is present throughout the spinal cord, and is most developed in the upper cervical regions. SpletThus approximately one-third of the axons in sacral tracts of Lissauer in the rat are propriospinal. Proportionately more myelinated than unmyelinated axons are lost. There are approximately equal numbers of surviving axons in the medial as opposed to the lateral part of the tract. This implies that there is, as yet, no morphological basis for ...
