Mid-fusiform sulcus

The mid-fusiform sulcus is a shallow sulcus that divides the fusiform gyrus into lateral and medial partitions.[1][2] Functionally, the MFS divides both large-scale functional maps and identifies fine-scale functional regions such as the anterior portion of the fusiform face area.[3]

Anatomy

Cytoarchitectonically, the lateral and medial sides of the MFS are dissociable.[1] The anterior and posterior portion of the MFS also have different long-range connections. The vertical occipital fasciculus terminates in the posterior aspects of the MFS, while the arcuate fasciculus terminates in the anterior portions of the MFS.[4]

History

The mid-fusiform sulcus was first identified in 1896 by Gustav Retzius. Retzius is known for many other discoveries such as Cajal-Retzius cells. He first identified the MFS as the sulcus sagittalis gyri fusiformis. Since his label, there have been several other proposed labels, but the MFS nomenclature is the most widely accepted in present day.[2]

gollark: Ah yes, that thing.
gollark: The thing a while ago with a something to Lua compiler?
gollark: What's this in response to?
gollark: So my search thing seems to be handling the tens of megabytes of slowly downloading esolangs.org data somewhat well, in that queries which don't have any results in it run fine. On the other hand, I didn't add any pagination and it would be quite hard to given how the search algorithm works, so looking for stuff like "the" is slow. And the search algorithm is terrible at looking up specific phrases.
gollark: Just text, formatting and a little metadata (in some insane XML format) - no images, talk pages, user pages, that sort of thing.
