There is an old idea that the visual cortex involved when we visualize past experiences or memorized material. It probably has a recall machinery. With the blind subjects, perhaps, this activity (dealing with abstractions) has been registered as a distinct (due to lack of sensory input), while in the control group it is drowned in the noise of normally functioning visual cortex. So, it is interesting but inconclusive. Also fMRI can't be used as a method of discovery, because it is based on very approximate statistical models. Something is going on there. Well, there always something is going on.
