This post started of as a look at YouTube material on Brodmann Area 13 but it looks as though there is some controversy about Brodmann Area 13 existing in humans with some sources stating that it has been identified only in the Guenon Monkey. Nevertheless there are a number of sources that identify an Area 13 in humans and further localise the area to the Posterior Insular Cortex. For the sake of simplicity I have collected Areas 13, 14 and 52 together and searched for material on YouTube using the term ‘Insular Cortex’. Having been developing a model of the Insular Cortex on YouTube, I wasn’t surprised to find these videos appearing in the search results and I’ve included them below (the model has been on the back-burner for a little while). Unfortunately the sound quality on these early videos isn’t great but that should be addressed with future updates.

Criticisms of the Model

In the usual mix of rock groups naming themselves or their song after a part of the brain (I note that the flocculonodular lobe is still up for grabs!) there were some useful educational videos on the Insular Cortex and it looks to be slightly more popular than other brain regions (on YouTube at least). In this video, the lecturer gives a straightforward account of the anatomical connections of the Insular Cortex which is displayed in lateral and coronal views.

Anatomical Relations of the Insular Cortex

There is a further detailed description of the anatomical relations in this video which includes schematics, models and anatomical sections.

Anatomical Relations of the Insular Cortex and a Discussion of the Neurophysiology

Professor Semir Zeki discusses the results of a neuroimaging study which shows an association between activity in the Insular Cortex and affiliative bonding.

Neurophysiology of the Insular Cortex

Searching for videos on YouTube sometimes retrieves unusual videos that give the impression that it is a search through the collective unconscious mind and I thought this video was a rather amusing example. It’s completely unrelated to the Insular Cortex other than to say it has Insula in the title but I thought the reader might be interested to see it.
