The human medial temporal lobe , crucial for memory, varies significantly across individuals making its study challenging. A recent study used in-depth imaging on individual subjects to discover new cortical networks associated with the MTL, revealing insights into human memory and potential evolutionary developments.
“One big challenge in studying the MTL is its great anatomical variability across people. Therefore, prior studies that were using group-averaged data, blurred fine anatomical details between different subregions of the human MTL that are located in close proximity to each other. It is like studying face structure by averaging 1000 different faces together.
Daniel Reznik concludes and adds: “Similar cortical networks also exist in animals and perhaps the most exciting finding is that we have now evidence for potentially new cortical pathways in the human memory system compared with non-human primates.”
