AI can tell where a mouse is by reading its brain activity

Analysing a mouse's brain activity tells scientists where the animal is located and the exact direction it is looking. With further research, the findings could one day help robots navigate autonomously. Mammalian brains use two main types of neurons for navigation: "head direction cells" show where an animal is facing and "grid cells" help provide a two-dimensional brain map of where it is located. To learn more about the firing of these neurons, Vasileios Maroulas at the University of Tennessee, Knoxville, and his colleagues – together with the US Army Research Laboratory – analysed data from a previous study.
