pretectal region in dogs

Nuclear complex between dorsal thalamus and optic tectum whose nuclei receive afferents primarily from the retina and the optic tectum and are involved in modulating motor behavior in response to visual input. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the pretectal region is

Nuclear complex between dorsal thalamus and optic tectum whose nuclei receive afferents primarily from the retina and the optic tectum and are involved in modulating motor behavior in response to visual input. The atlas records it as a nerve at the organ scale in the dog.

Where the pretectal region 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 pretectal region connects to

The atlas records 9 typed relationships for it, across 6 kinds of connection. part of brain.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the pretectal region. 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 area pretectalis, nuclei pretectales, pretectal area, pretectal nuclei, pretectum and area praetectalis, and 3 more. Searching any of those names reaches this page.

Questions

Where is the pretectal region?

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 pretectal region connect to?

Part of: brain.

Is the pretectal region 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.
