The critical brain hypothesis proposes that neural systems operate near a phase transition, potentially maximizing efficiency in information transmission, storage, and processing. Although hallmarks of criticality, such as scale invariance and non-Gaussian dynamics, have been observed in brain activity, establishing a direct connection between criticality and task outcome remains an open question. In this talk, we explore neuronal activity in the visual cortex of mice engaged in a visual recognition task using a phenomenological renormalization group (PRG) approach. Our findings point to intriguing relationships between neuronal scaling behavior and task performance under various conditions, offering new perspectives on the potential role of critical dynamics in cortical processing.
