A Neural Dynamics and Oscillator Interference Mixed Model of the Grid Cells for Spatial Recognition
Grid cells in the MEC(media entorhinal cortex)of rats show repetitive hexagon firing pattern while moving through the environment.In the deeper layer of the MEC,a kind of interneurons have both the head-directing(HD)and grid-like firing properties.The predecessors observations indicate the grid cells have ubiquitous intracellular rhythmic oscillating.Moreover,the grid cells firing frequencies have interesting approximate proportion relationship with the animals moving velocity.However,animals perception of the motor speed might be affected by many other factors such as visual signals or external information.The oscillation interference process inevitably follows with error accumulating.Based on what we have mentioned above,we put forward an improved grid cell model that handle speed signal in a plausible way and ameliorate the effects of phase noise.And this papers model is achieved by combining two prevailing theories together which might be closer to the scientific truth of grid cells.
