Section of the spinal cord (at the level of Th.2) from a patient suffering from tabes dorsalis, and showing degeneration of the tract of Goll (fasciculus gracilis). This tract conveys proprioceptive impulses from the lower extremity. The patient would have shown a typical ataxic gait, with loss of postural sense and tactile discrimination in the lower limbs. There would also be loss of vibration sense and ability to localize tactile stimuli. On the other hand, there would be no weakness or paralysis of the muscles of the lower limb.
