Dynamic changes in brain regions active while learning novel visual concepts were examined in humans using functional magnetic resonance imaging. Participants learned to distinguish between exemplars of two categories, formed as distortions of different unseen prototype stimuli. Regions of the right hemisphere (dorsolateral prefrontal and inferior parietal(More)
Functional magnetic resonance imaging (fMRI) was used to examine whether neural pathways used to encode pictures into memory were re-activated during retrieval of those memories. At encoding, subjects semantically classified common objects presented as pictures or words. At retrieval, subjects performed yes/no recognition memory judgments on words that had(More)
An influential neuropsychological finding in the field of human memory has been the dissociation of implicit from explicit memory. Explicit, or declarative, memory is memory for facts and events; it is dependent on the hippocampal and diencephalic brain systems (Cohen, Pol-drack, & Eichenbaum, 1997; Squire, 1994). Implicit memory is a heterogeneous set of(More)
