Nat Commun: Key neurons regulate the brain's spatial map

January 20, 2021 // --- sense of space is essential for daily life and memory formation.
recently, a study published in the journal Nature Communications found that removing glycosin around the brain's internal gps neurons makes the brain's spatial "map" unstable.
scientists at the University of Oslo in Norway have shown that sugar-encased extracellular substrine proteins, or extraneural neural networks, are tightly wrapped around neurons in the brain, which is why the brain's spatial map remains stable for a long time.
study is the first to link extracellular substrings to the stability of our sense of space.

"When we removed extrasurgery nerve networks from neurons in the olfactory cortical layer in rats, we observed that mutant mice were slower to form new mesh maps in the new environment than grid cells in rats with complete extraneural neural networks.
lead author Charlotte Christensen said that when the mice returned to their familiar environment, the spatial map of the brain became unstable.
suggests that neural networks help maintain the integrity of stored mental maps and prevent them from being covered by new experiences.
they found that not only was the spatial map fish unstable, but the precise time between the launches of grid cells was also affected when the neural networks around the nerves were removed.
opens the door to future research to clarify whether the confusion at the time or place of Alzheimer's patients is related to changes in the brain's extracellular substituts.
