“grid cells” encode an animal’s location and direction of movement in 2d physical environments via regularly repeating receptive fields. constantinescu et al.

A grid code for a 2d conceptual space in an imaginative leap, constantinescu et al. (2016) adapted this logic and exper imental design to ask whether the brain might use grid cells to encode not only physical, but conceptual, 2d spaces. for the experiment, they created a novel 2d spaceofbirdshapes.thetwodimensions were the leg and neck length.

Abstract. "grid cells" encode an animal's location and direction of movement in 2d physical environments via regularly repeating receptive fields. constantinescu et al. (2016) report the first evidence of grid cells for 2d conceptual spaces. the work has exciting implications for mental representation and shows how detailed neural coding. Indeed, it has been suggested that grid cells can map the passing of time 10, auditory space 11, imagined space 12 and conceptual cognitive space 13. furthermore, the underlying neuronal circuitry. Abstract. it has been hypothesized that the brain organizes concepts into a mental map, allowing conceptual relationships to be navigated in a manner similar to that of space. grid cells use a hexagonally symmetric code to organize spatial representations and are the likely source of a precise hexagonal symmetry in the functional magnetic. Grid cells, as a scalable position encoding method, can encode the spatial relationships of places and enable grid cells to outperform place cells in navigation. further, we extend the grid cell to images encoding and find that grid cells embed images into a mental map, where geometric relationships are conceptual relationships of images.
