| Meynert's fasciculus | A compact bundle of fibres arising in the habenula and passing ventralward to the interpeduncular nucleus at the base of the midbrain; part of its fibres bypass this nucleus and terminate in the raphe nuclei of the caudal mesencephalic tegmentum. Synonym: fasciculus retroflexus, habenulointerpeduncular tract, Meynert's fasciculus, Meynert's retroflex bundle. (05 Mar 2000) |

| Meynert's commissure | The commissural fibres that lie above and behind the optic chiasm. Synonym: Ganser's commissures, Gudden's commissures, Meynert's commissures, supraoptic commissures. (05 Mar 2000) |
| Meynert's decussation | The dorsal tegmental decussation (fountain or Meynert's decussation, decussatio fontinalis) of the left and right tectospinal and tectobulbar tracts, the ventral tegmental decussation (rubrospinal or Forel's decussation) of the left and right rubrospinal and rubrobulbar tracts; both are located in the mesencephalon. Synonym: decussationes tegmenti. (05 Mar 2000) |

(05 Mar 2000) |
| arcuate fasciculus | Long association fibre bundle lateral to the centrum ovale of the cerebral hemisphere, connecting the frontal, occipital, and temporal lobes; the fibres pass from the frontal lobe through the operculum to the posterior end of the lateral sulcus where many fibres radiate into the occipital lobe and others turn downward and forward around the putamen and pass to anterior portions of the temporal lobe. Synonym: fasciculus longitudinalis superior, arcuate fasciculus. (05 Mar 2000) |
| Burdach's fasciculus | The larger lateral subdivision of the posterior funiculus. Synonym: fasciculus cuneatus, Burdach's column, Burdach's fasciculus, Burdach's tract, cuneate funiculus, wedge-shaped fasciculus. (05 Mar 2000) |
| calcarine fasciculus | A group of short association fibres beneath the calcarine fissure of the occipital lobe of the cerebrum. (05 Mar 2000) |
| macular fasciculus | The collection of fibres in the optic nerve directly connected with the macula lutea. Synonym: fasciculus macularis. (05 Mar 2000) |
| mamillotegmental fasciculus | A small bundle of fibres that passes dorsalward from the mamillary body for a short distance with the mamillothalamic tract, then turns down the brainstem to reach the dorsal and ventral tegmental nuclei of the mesencephalon. Synonym: fasciculus mamillotegmentalis. (05 Mar 2000) |
| mamillothalamic fasciculus | A compact, thick bundle of nerve fibres that passes dorsalward from the mamillary body on either side to terminate in the anterior nucleus of the thalamus.

(05 Mar 2000) |
| medial longitudinal fasciculus | A longitudinal bundle of fibres extending from the upper border of the mesencephalon into the cervical segments of the spinal cord, located close to the midline and ventral to the central gray matter; it is composed largely of fibres from the vestibular nuclei ascending to the motor neurons innervating the external eye muscles (abducens, trochlear, and oculomotor nuclei), and descending to spinal cord segments innervating the musculature of the neck. Synonym: fasciculus longitudinalis medialis, Collier's tract, medial longitudinal bundle, posterior longitudinal bundle. (05 Mar 2000) |
