    Effects of Level of Retrieval Success on Recall-Related Frontal and Medial Temporal Lobe Activations by Daniela Montaldi, Andrew R. Mayes, Anna Barnes, Donald M. Hadley, Jim Patterson, David J. Wyper

    Published 2002-01-01
    “…The frontal activations occurred mainly in the dorsolateral region, but extended into the ventrolateral and, to a lesser extent, the frontal polar regions. It is argued that whereas the medial temporal lobe activation increased as the proportion of response words successfully recalled increased, the bilateral frontal lobe activation increased in proportion to retrieval effort, which was greater when learning had been less good.…”
