Highlights • Predictive coding explains the recursive hierarchical structure of cortical processes.• Granular layer 4, which relays ascending cortical pathways, is absent from motor cortex.• Perceptual inference results if ascending sensory data modify sensory predictions action, if spinal reflexes enact descending motor and/or proprioceptive predictions.• Motor layer 4 regresses as motor predictions inherently require less modification.

对无颗粒结构的思考:运动皮层的预测编码

亮点 • 预测编码解释了皮层过程的递归层次结构。• 运动皮层不存在传递上行皮层通路的颗粒层 4。• 如果上行感觉数据修改感觉预测动作,如果脊髓反射执行下行运动和运动,则感知推断结果/ 或本体感觉预测。• 运动层 4 退化,因为运动预测本质上需要较少的修改。
