Un séminaire du LPNC donné par Pr. Melissa C. Duff (Hearing and Speech Sciences, Vanderbilt University Medical Center)
Language use requires the rapid and incremental processing of flexible and contextually defined linguistic forms that are formulated in rich, multi-modal environments. How this is accomplished in the brain, however, is an open question. While attempts to link aspects of memory to particular properties of language are longstanding, hippocampal-dependent declarative memory has not received serious consideration as a neural/cognitive system involved in language use and processing. This is in part due to the long-held assumption that the hippocampal-dependent memory contributes only to long-term memory representations and not those that are available quickly enough to guide on-line information processing. Combining discourse analysis, eye-tracking, and neuropsychological methods I will present evidence for hippocampal contributions to language use and processing, both in the moment and over time, and across various domains of language. Linking disruptions in language use and processing to hippocampal-dependent declarative memory demonstrates how promiscuously the hallmark processing features of the hippocampus are called upon by a variety of cognitive domains, including language, and expands the network of neural and cognitive systems that support language use.
