FIGURE 13.

Intersections of inactive layer 5 loops and an inactive network system within a minicolumn. The thalamocortical input to the networks system is itself influenced by loops located near and far, as shown in the bottom-up and top-down arrows that contact the thalamic neuron shown in this figure. Informational pulse inputs to the networks system are indicated by axons from stellate neurons. On the left side of this figure, the diagram for minicolumns in higher order cortical areas indicates the vertical extent of layer 4, which is considerably shorter than in previous figures based on the primary sensory cortex of vision.
