dorsal longitudinal fasciculus in dogs

A fiber bundle containing fibers from nuclei of the hypothalamus that project to the dorsal tegmental nucleus and other regions of the midbrain and the pons, as well as fibers originating in the pontine reticular formation and the medullary reticular formation that project to the thalamus and other regions of the forebrain (Carpenter-83). In NeuroNames it is a composite structure consisting of the dorsal longitudinal fasciculus of hypothalamus, the dorsal longitudinal fasciculus of midbrain, the dorsal longitudinal fasciculus of pons and the dorsal longitudinal fasciculus of medulla. (NeuroNames). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the dorsal longitudinal fasciculus is

A fiber bundle containing fibers from nuclei of the hypothalamus that project to the dorsal tegmental nucleus and other regions of the midbrain and the pons, as well as fibers originating in the pontine reticular formation and the medullary reticular formation that project to the thalamus and other regions of the forebrain (Carpenter-83). In NeuroNames it is a composite structure consisting of the dorsal longitudinal fasciculus of hypothalamus, the dorsal longitudinal fasciculus of midbrain, the dorsal longitudinal fasciculus of pons and the dorsal longitudinal fasciculus of medulla. (NeuroNames). The atlas records it as a nerve at the organ scale in the dog.

Where the dorsal longitudinal fasciculus is

It sits within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the dorsal longitudinal fasciculus connects to

The atlas records 5 typed relationships for it, across 2 kinds of connection. part of brain, central nervous system and white matter.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the dorsal longitudinal fasciculus. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as bundle of Schutz, fasciculus longitudinalis posterior, fasciculus of Schutz, posterior longitudinal fasciculus, DLF and accessory cochlear nucleus, and 7 more. Searching any of those names reaches this page.

Questions

Where is the dorsal longitudinal fasciculus?

It sits within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the dorsal longitudinal fasciculus connect to?

Part of: brain, central nervous system and white matter.

Is the dorsal longitudinal fasciculus the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
