Recognizing, Recollecting, and Rejecting: The cognitive neuroscience of recognition memory.

Accumulating behavioral and neuroscientific evidence has suggested that recognition memory may be supported by at least two processes: the assessment of an item's familiarity and the recollection of the context in which an item was encountered. However, the functional nature of these processes and their neural substrates remain unclear. I will present results from studies using scalp-recorded event-related brain potentials demonstrating that recollection and familiarity are supported by independent neural systems at the time of encoding as well as retrieval. Next, I will report evidence from functional magnetic resonance imaging (fMRI) studies suggesting that these two processes differentially depend on encoding processing within different regions within the human medial temporal lobes. Finally, I will show that regions in the prefrontal cortex (PFC), thought to play a critical role in the control of memory activations, contributes to both familiarity and recollection.

Representation and control processes in visual working memory.

Working memory is a neurocognitive system that allows us to activate, maintain, and manipulate complex information in the absence of external stimulation. Functional neuroimaging has revealed new insights into the neural bases of working memory, but these new developments necessitate changes in the cognitive models used to explain working memory phenomena. In this talk, I will present work from my lab investigating the neural basis of visual working memory. These findings suggest new insights into the way information is maintained in working memory, and the executive control processes that allow us to transform perceived information into a code that can be actively maintained.
