Appendix 4—figure 1. Unrolled network diagrams for the pre-gating (A) versus the post-gating (B) models.

The EM gate in the pre-gating model controls the degree to which stored memories are activated within the LCA module, but does not control the degree to which the activated memories are transmitted to the neocortex. By contrast, the EM gate in the post-gating model controls the degree to which activated memories in the LCA module are transmitted to the neocortex, but it does not control how these memory activations are computed in the first place.
