Open Question

AbstractDuring associative retrieval, the brain reinstates neural representations that were present during encoding. The human medial temporal lobe (MTL) with its subregions hippocampus (HC), perirhinal cortex (PRC), and parahippocampal cortex (PHC) plays a central role in neural reinstatement. Previous studies have given compelling evidence for reinstatement in the MTL during explicitly instructed associative retrieval. High-confident recognition may be similarly accompanied by recollection of associated information from the encoding context. It is unclear, however, whether high-confident recognition memory elicits reinstatement in the MTL even in the absence of an explicit instruction to retrieve associated information. Here, we addressed this open question using high-resolution fMRI. Twenty-eight male and female human volunteers engaged in a recognition memory task for words that they had previously encoded together with faces and scenes. Using complementary uni- and multivariate approaches, we show that MTL subregions including the PRC, PHC, and HC differentially reinstate category-specific representations during high-confident word recognition, even though no explicit instruction to retrieve the associated category was given. This constitutes novel evidence that high-confident recognition memory is accompanied by incidental reinstatement of associated category information in MTL subregions, and supports a functional model of the MTL that emphasises content-sensitive representations during both encoding and retrieval.

Word Relatedness

Aphasic and non-neurological patients were assessed on a word recognition memory task. On any one trial, some words were instances of the same superordinate category, thus presupposing a common abstract conceptual feature, and some words could be linked thematically in the sense of forming context-dependent relations. Observing the temporal order in which patients pointed to the words they recognized permitted an assessment of the extent to which they clustered their responses either in terms of superordinate categories or along thematic lines. The conceptual structures indicated by these clusters were compared with those observed in a previous task requiring judgments of word relatedness. The data suggest that verbal memory limitations in aphasia are only in part linked to constraints on the conceptual features structuring lexical knowledge; and relatedly they raise the possibility that aphasics may have a disturbance of mnemonic processing quite apart from any disruption to language.
