This study proposes an entorhinal-hippocampal spiking neural network (SNN) encoding the position of self and other, and investigates an application to an observational T-maze task. On an observational T-maze task, the observer needs to represent the self-position and the position of the other in the brain. In the hippocampus, there are place cells that encode self-location in the environment, and some of them are joint place cells that encode the location of others as well. However, how joint place cells are formed is not yet understood. In the present study, we assume that object vector cells in entorhinal cortex encodes the distance and direction to others, and propose the entorhinal-hippocampal SNN that forms joint place cells by projections from place cells and object vector cells. Furthermore, the proposed SNN learns to move in the opposite direction of its companion at a T-junction based on the neural activity of joint place cells and rewarded signals. As a result, we confirmed that the proposed SNN can perform the observational T-maze task successfully through repeated trials. |
