According to MAY-BRITT MOSER. She is a Nobel Laureate in physiology.
Some years ago, Edvard Moser and May-britt Moser began studying cells in the brains hippocampus.She worked with John O'Keefe in London on this.According to she'place cells' are active at one specific place in the enviroment of our brain,because he knew off historical procedures where,for patients suffering from epileptic seizures,parts of the brain,including the hippocaampus on both sides,had to be removed.when this was done,the patients were intellectually and socially fine,but they could not remember new episodes,faces or name.
John found hippocampal cells help encode locations in the environment.If you lose hippocampal cells means losing that information.When Edvard and May Moser returned to Norway,They asked,where is this spatial information coming from?
They began researchin the entorhinal cortex,a structure in the brain that talks to the hippocampus.with sensors,they recorded tiny electrical signals from individual cells.They found singal cells in this formation had many activity fields in the environment,distributed in a way that resembled hexagonal tiling on a floor.They called this structure 'grid cells'whose field covers the entire environment.The grid cells generate spatial information our brain then anchors the grid map to the environment.Whatever site we have a room,a street,anywhere in this huge world gride cells funcation constantly in our mind with Neuropixels technoloogy,we can record thousands of these cells at te same time.
