The critical brain hypothesis posits that neural systems operate near a critical phase transition, potentially optimizing computation and information processing. However, the precise relationship between criticality and performance in living systems remains a mystery. In this companion study to “Neuronal Scaling in the Mouse Visual Cortex During a Visual Recognition Task,” we extend our investigation to other brain regions as mice perform a visual task. Using the phenomenological renormalization group (PRG), we assess whether these regions exhibit signatures of criticality akin to those observed in the cortex, and how these dynamics change during task performance.
