grid cells

Grid cells are specialized neurons in the brain's entorhinal cortex that help with navigation and spatial awareness. They fire in a pattern that forms a virtual coordinate system, creating a grid-like map of an environment. As you move, these cells activate at regular intervals, enabling precise tracking of your position relative to landmarks. This internal grid aids in understanding where you are and planning routes, working together with other spatial cells like place cells. Essentially, grid cells function as an internal GPS, helping humans and animals navigate complex surroundings efficiently.
