A search of YouTube was undertaken to identify relevant material on Brodmann Area 21. The search term ‘Brodmann Area 21’ was used which returned 6 videos (without duplication). 3 of the videos were not relevant while 3 were in Spanish. There is a facility for translating videos on YouTube although none of them featured English subtitles and I wasn’t able to understand 2 of them. However a third was understandable as it had English text and the diagrams were fairly self-explanatory. Indeed the video is very slick – showing associations using the research literature as a foundation with an accompanying music track to help keep the focus. Fear, happiness, sadness, observation of action and motor learning are all associated with Brodmann Area 21 in the following video.
