THE MID-BRAIN 899 The medial lemniscus, or principal conduction path for sensor impulses from the trunk and extremities, and already discussed in the preceding (p. 876), ascends in the tegmentum of the mid-brain in the contact zone with the crusta. In its ascent it is deflected slightly dorsolaterad by the red nucleus. The lateral border of the ribbon-like bundle is in contact with the lateral lemniscus, and forms an angle with it, as seen on trans-section (Figs. 663 and 664)..

Fig. 665.—The medial longitudinal bundle in black and red. Lateral lemniscus i identified by comparison with Fig. 648.) Many of the fibres of the medial lemniscus terminate in the superior quadri- geminal body; the remainder proceed to the thalamus. The superior peduncles or prepeduncles of the cerebellum sink into the mid-brain tegmentum in a cephaloventral direction, the two superior peduncles converging and their fibres undergoing a complete decussation (Wernekinck's commissure) subjacent to the inferior quadrigeminal body. The crossed fibres end, for the most part, in the red nucleus of each side; others circumvent the nucleus forming.
