[vimeo link]Spatial representation in the brain allows us to navigate and understand our environment by constructing internal maps. It involves specific brain areas, particularly the hippocampus and the entorhinal cortex. The hippocampus contains "place cells," which activate when an animal or person is in a particular location within an environment. Each place cell corresponds to a specific location, collectively forming a mental map of surroundings.

The entorhinal cortex, located near the hippocampus, has "grid cells," which activate in a hexagonal pattern as we move through space, providing a stable coordinate system that helps in navigation.

The film shows how researchers train models on neural data to predict an animal’s location or movement through a space based solely on neuron firing patterns.
