During the second scan, subjects had to make judgments about words that were not presented. For example: bed, rest, dream, tired, and awake would be in the list but not the word "sleep". As with the study by Henry L. Roediger and Kathleen McDermott, subjects claimed to remember similar amounts of non-presented words as they did the words that were actually presented. The researchers noted that brain activity during the true and false recognition tasks were very similar. Monitoring the blood flow in the brain revealed there were in the left medial temporal lobe for both veridical and illusory recognition. That is not to say that there were not differences. While monitoring blood flow in the brain during false recognition, a part of the frontal lobe that is thought to be a key monitor of memories actually showed greater activity when presented with a false recognition than with a true one. There seemed to be some discrepancy as subjects attempted to scrutinize the out-placed words, but were overcome by powerful memory illusion. This study demonstrates the ability of technology to help researchers understand to a greater extent the power of false memories. Source confusion and FMRI scans T. Awipi and L. Davachi sought to provide evidence of competing subregions in the medial temporal lobe (MTL) that differed on the type of content they encoded. The researchers conducted a study in which subjects were asked to perform an encoding task in a functional magnetic resonance imaging (FMRI) scanner, where they were presented with 192 full colour photographs of scenes (containing a centrally presented novel scene and a smaller image of one of six objects). Participants were also instructed to imagine using the presented object in each scene, and were asked to report whether they were successful. A memory test was administered after participants were removed from the scanner. The test consisted of all previously viewed scenes (old) and an equal number of novel scenes (new). They were asked to make an old/new judgement, and if the scene was responded as being old, they were asked to report it as being "remembered" or "familiar". They were then asked to pick an object that was paired with that scene. The researchers were trying to determine the levels of activation for source recollection for the objects paired with the scene during encoding. The researchers found that perirhinal cortex activation was greater for objects recalled,
