PFC-inspired AI model uses synaptic plasticity for goal-directed action planning

By PulseAugur Editorial · [1 sources] · 2026-06-02 10:59

Researchers have developed a reservoir computing model inspired by the prefrontal cortex to understand how goal information is maintained for action planning. Their study incorporated short-term synaptic plasticity (STP) into the model, finding that STP is crucial for stabilizing goal-conditioned dynamics, especially under noisy conditions. The model with STP demonstrated significantly higher success rates in a multistep action selection task compared to a model without STP, suggesting STP dynamically modulates effective recurrent connectivity to preserve goal information.

Short-Term Synaptic Plasticity Stabilizes Goal-Conditioned Dynamics in a PFC-Inspired Reservoir Model for Multistep Goal-Directed Action Planning

The prefrontal cortex (PFC) maintains goal information for action planning, but how recurrent circuits preserve it in an action-usable form over behavioral timescales remains unclear. Here we ask whether short-term synaptic plasticity (STP) can stabilize goal information as actio…
