I’ve written previously about searching on YouTube for information on the Brodmann Areas. The brain is a complex structure and but can be organised according to several principles. One approach is to characterise the brain regions according to the microscopic properties of these regions. More specifically the neurons are organised differently between regions. Some regions may contain unique types of neurons. This approach to understanding the organisation of the brain was proposed by the German Neuropathologist Korbinian Brodmann and resulted in the eponymously named Brodmann Area. There are 52 areas in all and I have covered other Brodmann Areas elsewhere. I have also written about one specific area – Brodmann Area 26 in another article where I remarked on the relative paucity of research papers on this area. Brodmann Area 26 is part of the Retrosplenial Cortex. What tends to happen is that when you move from the research literature to YouTube, there is a sharp drop in the number of results unsurprisingly. However as per previous posts in this series, some of the videos returned have been quite instructive and useful in getting a quick overview of structure and function. However given the paucity of research literature and the expected sharp drop off of returns from the search I anticipated this search wasn’t going to produce too many interesting results.
The search term ‘Brodmann Area 26’ was used which returned 8 videos specific to ‘Brodmann Area 26’ with some additional videos added at the end of the search for more general term ‘Brodmann Area’. So here are the videos.
The first one is from the more generic search term. A man holds up a brain with Brodmann Areas marked on the surface and rotates one hemisphere slowly for the audience to visualise the regions. However I’m not sure how the surface markings have been achieved and there’s little additional information.
Similarly in this video, the author has rendered a 3-dimensional representation of the brain averaged from T1-weighted MRI scans of 27 subjects using ‘space software’. The brain has lots of nice colour demarcations for regions but there is no assignation of numbers to these regions, the brain revolves fairly rapidly and the clip is short with no narrative.
There were a few interesting videos on other Brodmann Areas that turned up in the search as well as more general videos on the Brodmann Areas which just happened to miss out Brodmann Area 26.
In conclusion at this point in time, other than a video illustrating the surface correlation of Brodmann Area 26 the search didn’t produce many relevant results although compared to previous searches it’s obvious that this area is starting to evolve with a range of higher quality but more general
y neuroanatomy videos.
