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 Parietal Lobe to Brodmann Areas 5, 7, 39 and 40. In the title of this post, I have described this region as the spatial and somatosensory region. There is an important distinction here however. The non-dominant Temporal Lobe which appears to function as a store of spatial memory. The Parietal Lobe on the other hand helps us to interpret spatial information. There is a further distinction of note which is that there is an incomplete overlap between the Parietal Lobe and the Parietal Region as per Brodmann’s description. However for the purposes of this post these regions can be considered the same particularly in view of the initial search results.
When I undertook a search of Youtube for Brodmann Areas 5, 7, 39 and 40 I was unable to identify any relevant results that had not been returned from searches covered in previous posts (for other Brodmann Areas). Turning to the alternative search term ‘Parietal Lobe’ the search returned approximately 375 videos. I scanned through the video descriptions and identified the most relevant videos which are given below.
