New hippocampal network model achieves optimal navigation via dynamic relaxation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel hippocampal recurrent network model that demonstrates optimal goal-directed navigation through dynamic relaxation. This model represents spatial locations as neuron activities and uses connection weights to signify transition probabilities, with obstacles represented by vanishing weights. The network learns these connections via behavioral-timescale synaptic plasticity and, upon receiving a goal signal, its dynamics relax into an activity field mathematically equivalent to a Linearly-solvable Markov Decision Process (LMDP). This approach offers an efficient and robust method for navigation in complex environments, with potential applications beyond spatial navigation to general planning in abstract rational maps within the brain.

    Planning as Dynamics Relaxation: Hippocampal Recurrent Network Realizes Optimal Goal-Directed Navigation

    arXiv:2609.13219v1 Announce Type: cross Abstract: Neural correlates of spatial cognitive map are well documented, yet exactly how neural circuits perform spatial navigation in complex environments - e.g., reaching a goal while avoiding obstacles - remains largely unclear. Here, w…
