Imaging the medial temporal lobe: exploring new dimensions.
Cognitive scientists have used developments in functional imaging to explore the role of the medial temporal lobe (MTL) in memory formation. Lesion studies have suggested that separate MTL subregions make distinct contributions to memory. Functional imaging of these distinct contributions, however, remains a challenge, because the proximity of the MTL substructures tests the spatial resolution limits of current techniques. Recent findings using electrophysiological measures of neural activity highlight the importance of using information from other imaging modalities. Integrating the different modalities of neuroimaging with lesion studies, and, further, combining modalities within experiments, will provide new insights into the function of MTL subregions.
