My interest is in pre- and post-retrieval processes in prefrontal
and posterior parietal cortex.
Pre-retrieval: Given the role of the superior parietal lobe
in directing attention voluntarily to the external space, I am investigating
whether this brain region also directs retrieval attempts (i.e.
memory search).
Post-retrieval: Ventromedial (VMPFC) and dorsolateral prefrontal
cortex (DLPFC) are both crucial to support the evaluation of memories,
but there is initial evidence that these 2 prefrontal regions might
mediate distinct monitoring processes. Patients with lesions in
ventromedial prefrontal cortex may confabulate, that is, they may
claim to remember events that did not actually happen. In these
patients, false memory is promoted by irrelevant information emerging
during retrieval, and suppressed when cognitive resources available
for processing such information are experimentally reduced. I think
that in confabulating patients early VMPFC monitoring processes,
such as feeling-of-knowing, are "tricked" by task-irrelevant
information, which may prevent them from triggering (potentially
intact) DLPFC monitoring processes. I would like to explore how
the output from early monitoring processes affects later ones.
Once a memory has passed these prefrontal gates, it needs to enter
consciousness in order to be experienced as a memory. Given the
role of the inferior parietal lobe in the automatic allocation of
attention to salient features of the environment, I am investigating
whether this brain region also mediates the involuntary attentional
capture by the retrieved memory (i.e. memory detection). I believe
that similar mechanisms mediate confidence for percepts and memories.
