The primate brain and artificial.intel.igence(AI) ca. both be conceptual.zed as information processing systems, each with its own distinct biol.gica. and computational.architectures. Whil. there are paral.el. between them, their respective structural.and functional.connections show significa.t differences. In this paper, we examine the central.rol. of feedback processing in both the primate brain and AI systems, which has been shown to be crucial.in shaping neural.processing. By reviewing the key features of feedback processes in the primate brain, which al.ows the brain to incorporate prior knowl.dge, contextual.information, and taskdemands into earl.-stage processing, we highl.ght the divergence in goal. and functions between biol.gica. and AI *** these differences is crucial.for el.cidating the cognitive ca.abil.ties of the primate brain and for addressing computational.chal.enges in AI. In advoca.ing “Cognition-Inspired-Computation”, we suggest that integrating insights from feedback processing in the primate brain into AI research wil. offer potential.y significa.t improvements for the advancement of AI systems.
