Abstract in brief

The article presents a theory that cortical responses are driven by the brain's goal to infer and represent the causes of sensory inputs, using principles from statistical inference.
Both perceptual inference and learning are explained as processes that minimize the brain's free energy, a concept borrowed from statistical physics, allowing the brain to efficiently encode sensory information and update its beliefs.
Using hierarchical models and Bayesian principles, the theory suggests that cortical organization and responses are dynamically shaped by prior expectations and ongoing sensory experiences, providing a unified framework for understanding brain structure and function.]

Or put another way, my level of interest is “I just read Friston’s “A Theory of Cortical Responses” for fun but am concerned about the difficulty of grad school as a person w disability”

@AsafKlaf @edwinderaaij @CogsAndy @Mark_Solms Well as far as I know these frameworks originally started from the viewpoint of the cortex (https://t.co/Kaez9rghNS) but people moved on from there (https://t.co/HD8J80zk9v).
