YouTubing the Retrosplenial Region (AKA Brodmann Areas 26, 29 and 30)

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 Areas. There are 52 areas in all and I have covered other Brodmann Areas elsewhere (see Appendix). In his work ‘Localisation in the Cerebral Cortex’, Brodmann assigned the Retrosplenial Cortex to Brodmann Areas 26, 29 and 30. Brodmann Area 26 has been covered in this post previously. Brodmann identifies the Retrosplenial region as overlapping with the Corpus Callosum but is essentially the Isthmus of the Cingulate gyrus. Rather than include the Corpus Callosum in this section, I will focus on the Cingulate gyrus. There were a number of videos on the Anterior Cingulate Cortex covered elsewhere and again I will avoid repeating those covered again here (e.g if the video includes generic coverage of the Cingulate Cortex). The search terms Brodmann Area 26, Brodmann Area 29 and Brodmann Area 30 as expected from previous searches didn’t produce many results although the ‘Cingulate gyrus’ did. The most salient results are included below.
