| stratum lemnisci | A largely fibrous (hence whitish) layer of the superior colliculus separating the middle gray layer of superior colliculus from the deep gray layer of superior colliculus and containing, among others, fibres from the spinal and trigeminal lemnisci. Synonym: fillet layer. (05 Mar 2000) |
| nucleus lemnisci lateralis | A substantial cell mass embedded in the lateral lemniscus, immediately below the latter's entry into the inferior colliculus; the nucleus represents a synaptic way-station for part of the fibres of the lateral lemniscus. Synonym: nucleus lemnisci lateralis. (05 Mar 2000) |
| trigonum lemnisci | A triangular area on the lateral surface of the caudal half of the mesencephalon, bordered caudally by the slight prominence of the lateral lemniscus, dorsally by the base of the inferior colliculus and the brachium of the superior colliculus, and ventrally by the crus cerebri. Synonym: Reil's triangle, triangle of fillet, trigone of fillet, trigonum lemnisci. (05 Mar 2000) |
| decussatio | 1. In general, any crossing over or intersection of parts. 2. The intercrossing of two homonymous fibre bundles as each crosses over to the opposite side of the brain in the course of its ascent or descent through the brainstem or spinal cord. Synonym: decussation. Origin: L. (see decussate) (05 Mar 2000) |
| decussatio brachii conjunctivi | The decussation of the left and right superior cerebellar peduncles in the tegmentum of the caudal mesencephalon. Synonym: decussatio pedunculorum cerebellarium superiorum, decussatio brachii conjunctivi, decussation of brachia conjunctiva, Wernekinck's decussation. (05 Mar 2000) |
| decussatio fontinalis | See: decussationes tegmenti. (05 Mar 2000) |
| decussatio lemniscorum | The intercrossing of the fibres of the left and right medial lemniscus ascending from the gracile and cuneate nuclei, immediately rostral to the level of the decussation of the pyramidal tracts in the medulla oblongata. Synonym: decussatio lemniscorum, decussatio sensoria, decussation of the fillet, sensory decussation of medulla oblongata. (05 Mar 2000) |
| decussatio motoria | An alternate term for pyramidal decussation. (05 Mar 2000) |

| decussatio pedunculorum cerebellarium superiorum | The decussation of the left and right superior cerebellar peduncles in the tegmentum of the caudal mesencephalon. Synonym: decussatio pedunculorum cerebellarium superiorum, decussatio brachii conjunctivi, decussation of brachia conjunctiva, Wernekinck's decussation. (05 Mar 2000) |
| decussatio pyramidum | The intercrossing of the bundles of the pyramidal tracts at the lower border region of the medulla oblongata. Synonym: decussatio pyramidum, decussatio motoria, motor decussation. (05 Mar 2000) |
| decussatio sensoria | An alternate term for decussation of medial lemniscus. (05 Mar 2000) |
