Is this what module closure looks like?

In their experiments reported in the September 1, 2005, issue of Neuron, the researchers [Anthony D. Wagner, Brian D. Gonsalves, and Itamar Kahn of Stanford University] asked volunteers to look at series of faces as the subjects' brains were scanned.

The researchers asked the subjects to rate their familiarity with each face as "remembering" if they strongly recalled the face, "knowing" if they had a feeling of recognizing the face, or "new" if they didn't recall seeing the face before.

The fMRI scans revealed that the decrease in medial temporal lobe activity tracked the level of perceived memory strength for the faces.

Gonsalves and his colleagues concluded that "medial temporal structures, in the service of declarative memory, support recognition of stimuli that were previously encountered, allowing organisms to discriminate between novel and familiar items.

A decrease in activity looks a lot like turning off a TOTE unit. I would assume that the TOTE unit gets a face and the quest question: “Do we have a previous image of this face in storage?” The TOTE unit will exit when the test returns a yes, meaning that a recognizing unit has made an adequate match with the input. If a name is needed, the recognizing unit will now try to activate another unit that can say the name.
