Robbins and colleagues used mouse cortical organoids in a closed-loop pole-balancing task. A high-density electrophysiology system translated task state into stimulation and recorded neural responses while the training protocol selected feedback signals.
The 2026 Cell Reports paper reported improved task performance under the goal-directed training condition. Blocking AMPA and NMDA receptors abolished the performance improvement, supporting the interpretation that synaptic plasticity contributed to the adaptation.
Evidence status
Peer-reviewed research demonstration. It provides evidence for goal-directed adaptation in this experimental setup, not a general claim that organoids outperform conventional reinforcement-learning controllers.
