Putative pathophysiological pathways of migraine with aura, AIWS, and VSS.

	Pathophysiological Pattern
Migraine	CSD proceeds in a posteroanterior way in all directions starting from the visual cortex; Increase and subsequent reduction of the BOLD signal from the V3A area to the visual cortex
Alice In Wonderland Syndrome	CSD involves neurons of the TPO-C area Cortical dysfunction due to hypoperfusion
Visual Snow Syndrome	Hyperactivity of supplementary visual cortex V3A
