Flechsig's tracts

Related people

A compact bundle of heavily myelinated, thick fibres at the periphery of the dorsal half of the lateral funiculus of the spinal cord. They originate in the Clarke's column (the ipsilateral thoracic nucleus) and ascend by way of the inferior cerebellar peduncle. The bundle conveys largely proprioceptive information originating from the annulospinal nerve endings surrounding muscle spindles and from Golgi tendon organs.
