Hippocampal BMI overview and mental navigation task (VIDEO)
Caption
A new brain-machine interface and virtual reality system for rats. In this experiment, a rat uses this system to navigate to a goal solely by thinking about where it wants to go. According to the rules of this system, physical movement by the rat does not affect the rat's location in the virtual environment. Only by controlling its hippocampal brain activity can the rat control where it goes. Specifically, in this system the animal is virtually moved toward the 'decoded location' that the hippocampal activity represents.
