The drones first fly over an area to map it, collecting data about the topography and soil condition that can be combined with satellite data and analyzed to determine the best locations to plant each seed. Then the drone fires biodegradable pods—filled with a germinated seed and nutrients—into the ground.
“Cognitive spaces are a way of thinking about how our brain might organize our knowledge of the world,” Bellmund said. It’s an approach that concerns not only geographical data, but also relationships between objects and experience. “We were intrigued by evidence from many different groups that suggested that the principles of spatial coding in the hippocampus seem to be relevant beyond the realms of just spatial navigation,” Bellmund said. The hippocampus’ place and grid cells, in other words, map not only physical space but conceptual space. It appears that our representation of objects and concepts is very tightly linked with our representation of space.
