Unveiling the Brain's New Mnemonic Networks: The Anatomy of Memory

Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences have used precision neuroimaging and high-resolution fMRI to explore the human memory system. They discovered previously unknown cortical networks associated with different subregions of the medial temporal lobe (MTL), shedding light on the anatomical organization of the human memory system. The study's findings provide insights into the connectivity of the MTL and its potential implications for understanding Alzheimer's disease. The research also suggests the existence of new cortical pathways in the human memory system compared to non-human primates, potentially related to social processing.

New Brain Structure Discovered by Scientists

Scientists have discovered a new anatomical structure in the brain called SLYM, which acts as a barrier and a platform for immune cells to monitor the brain. The SLYM is a thin but tight membrane that separates "clean" and "dirty" cerebrospinal fluid (CSF) and appears to play a critical role in the glymphatic system, which removes toxic proteins associated with Alzheimer's and other neurological diseases from the central nervous system. The SLYM also hosts its own population of central nervous system immune cells that use it for surveillance at the surface of the brain, allowing them to scan passing CSF for signs of infection. The discovery of the SLYM opens the door for further study of its role in brain disease and drug delivery to the brain.
