A vertical cylinder of cells extending through all 6 neocortical layers has been repeatedly proposed as the elementary functional unit of cerebral cortex. This concept was first clearly stated by Lorente de N6, with reference to the anatomical organization of neocortex 12, over 30 years ago. Later Mountcastle introduced the concept of a functional 'column' of cortex, based on the response properties of single units in somatosensory cortex 13. Hubel and Wiesel extended this physiological concept… CONTINUE READING
