Allocortical areas other than hippocampus with <3 layers?

There are many different micro-architectures for cortex tissue. Isocortical tissues have 6 layers, Agranular Tissues have the same general architecture but are missing or only have minimal 4 th layers, and Allocortical are no longer 6 layers but often 3 or less. Most allocortical areas have three layers, but at lest one area in the hippocampus has a different architecture. For the purposes of this question I call the thee layer allocortical tissues stacked tissues, and the hippocampus tissues wrapped or coiled tissues. It is known that the orientation of the pyramidal cells in the stacked cortex tissues is vertical, and hte orientation of the pyramidal cells in the coiled tissues is radial. My question is, are there any other areas, that have allocortical tissues that are not thee layers or more other than the hippocampus?
