such a statement ("region contains the relevant information") indeed
would have sufficient support from "MVPA ROI analysis"... I was
discussing those additional statements, which I could have just
misunderstood/mistreated: such as "common network" and "the difference
between the two lies within this network" which sounded to me trying to
dismiss the possibility that there could also be another location
supporting this hypothesis.
