Abstract

In the realm of advanced cognitive processes, animals employ both egocentric and allocentric reference frames for navigation. While prior studies have largely concentrated on differentiating and transitioning between these frames, the present research explores the concurrent use of both strategies in navigation tasks. By simulating the entorhinal-hippocampal neural circuit and applying reinforcement learning (RL), we developed three agents characterized by egocentric, allocentric, and a novel integrated strategy. Testing across diverse navigation scenarios revealed that the integrated model substantially improved navigation adaptability and efficiency. Despite the challenges associated with the "black box" nature of RL, the artificial combination of individual reference frames notably enhanced performance. These results shed light on novel mechanisms of biological spatial information processing and the flexible organization of navigation strategies
