    Title:
    Investigating recollection in source memory as a model task
    for hippocampal-prefrontal interaction: An EEG approach
    Abstract:
    In the dual-process model of recognition memory, recollection refers to the remembering of a target
    item together with additional contextual details from the learning episode. Recollection was shown
    to rely on the hippocampus and the prefrontal cortex which is presumably due to item-context binding
    and the strategically guided retrieval of those associations. Investigating event-related potentials
    (ERPs; e.g. old/new effects) and oscillatory phenomena (e.g. cross-frequency coupling) can give indirect insights in the hippocampal-prefrontal network. In order to further characterize age-related changes in the network underlying recollection, we conducted a source memory experiment with picture-location
    pairs in young adults and healthy seniors. In this talk, ERP results from the encoding and retrieval parts of the experiment will be presented and an outlook on upcoming analyses regarding connectivity in the hippocampal-prefrontal network will be given.
