Brain’s GPS system influenced by shape of environment

Standard

Professor John O’Keefe (UCL Cell & Developmental Biology, Director of the Sainsbury Wellcome Centre and Nobel Prize laureate in Medicine or Physiology 2014) , senior author on the paper, said: “We know that other cells involved in the brain’s GPS system such as place cells and boundary cells are affected by environmental geometry and now we see the same is true for grid cells. It might be that grid patterns aren’t used as a ruler by the brain and are doing something different. Of course, they may still be trying to measure distance in trapezoids but this is now distorted, leading to the interesting idea that our brains perceive distance differently in environments with polarised geometry. Our next step will be to find out why grid patterns change based on our environment and what this means for the role of grid cells in helping us navigate and form memories.”
