“…Consistent with this interpretation, a recent study reported that real object induced a large P600, whereas nonsense objects induced no P600 (Vannucci et al, 2003). In another study, this wave was found to be larger for famous as compared with nonfamous faces (Trautner et al, 2004). Both studies suggested that objects with rich semantic associations activated the hippocampus.…”

“…In addition to this role in memory processing, the P600 may also reflect more general semantic processing. This was suggested by findings of a larger P600 for real objects than for nonsense objects (Vannucci et al, 2003), and a larger P600 for famous faces than nonfamous faces (Trautner et al, 2004). Thus, the P600 might reflect associative processing of items in both memory encoding and continuous recognition tasks.…”

Word imageability affects the hippocampus in recognition memory

Concrete words, whose meanings are readily imagined, are better remembered than abstract words. However, the neural correlates of this effect are poorly understood. Here, we investigated the effect of imageability on brain activity in the medial temporal lobe (MTL) processes underlying recognition memory. We recorded event-related potentials (ERPs) via depth electrodes from within the MTL in 14 patients with drug-resistant epilepsy. Patients performed a continuous word recognition task with words of high and low imageability (controlled for word frequency). Behaviorally, recognition performance was better for high, compared to low, imageable words. Two ERP components associated with recognition memory, the AMTL-N400 and the hippocampal late negative component, showed an old/new effect, but only the hippocampal P600 showed a main effect of imageability. We suggest that the hippocampal effect of imageability in recognition memory may be associated with conceptual or pictorial information processing of concrete words.

“…This ''parietal old/new effect'' is maximal over centro-posterior scalp sites and takes the form of a positive shift to repeated pairs (Donaldson & Rugg, 1998Weyerts et al, 1997, but see Tsivilis et al, 2001). It has been proposed, and intracranial recordings have provided data to support (e.g., Dietl et al, 2005;Trautner et al, 2004), that this late positive complex, hereafter referred to as the LPC, reflects processing in medial temporal lobe structures (i.e., hippocampus). 1 To date, no experiment has provided evidence for ERP effects earlier than the LPC that distinguish between maintained and rearranged pairs of items.…”

Various lines of evidence suggest that memory for the relations among arbitrarily paired items acquired prior to testing can influence early processing of a probe stimulus. The event-related potential experiment reported here was designed to explore how early in time memory for a previously established face-scene relationship begins to influence processing of faces, under sequential presentation conditions in which a preview of the scene can promote expectancies about the to-be-presented face. Prior to the current work, the earliest component documented to be sensitive to memory for the relations among arbitrarily paired items was the late positive complex (LPC), but here relational memory effects were evident as early as 270-350 msec after face onset. The latency of these relational memory effects suggests that they may be the precursor to similar effects observed in eye movement behavior. As expected, LPC amplitude was also affected by memory for face-scene relationships, and N400 amplitude reflected some combination of memory for items and memory for the relations among items.

Recognition of famous faces in the medial temporal lobe

Abstract: The anterior medial temporal lobe N400 and the hippocampal P600 may be related to the access and retrieval of person-specific semantic memory.
