Previous lesion research with non-human primates has demonstrated the hippocampal involvement in delayed match and non-match to sample (DMS/DNMS) tasks. Earlier functional imaging work in our laboratory with humans has found that BOLD activity in the medial temporal lobe (MTL), in particular the right hippocampus, is increased during performance of the memory task. The present study extends this line of work by investigating development of the neural correlates underlying memory on the DMS/DNMS task. The hippocampal activity of 7-12 year old children was investigated using high resolution (4 Tesla) event-related functional magnetic resonance imaging (fMRI). Results indicate that children recruit similar brain regions as adults, suggesting that at least by this age, children’s reliance on MTL structures is at or very close to adult levels.
