Title : The effect of normal ageing on the hemispheric specialization of language and its modulation by lifestyle factors.

When one sees “cognitive ageing” he usually imagines cognitive decline. There is evidence that old adults are slower and even less accurate in some cognitive functions, such as working memory or attentional processes, compared to young adults. But cognitive ageing also means functional plasticity. Many authors have studied the age-related changes on cerebral activity for different cognitive functions and have found that (1) some cognitive functions are longer preserved than other, (2) some old adults perform better than other, and (3) age-related changes on cerebral activity may take different forms. In my project I am interested by the effect of age on the hemispheric specialization of lexico-semantic processing and its modulation by lifestyle factors. The study of the lexico-semantic processing is motivated by several aspects, including the fact that the semantic processing remains stable over a long time during normal ageing whereas older adults may undergo tip-of-the-tongue phenomenon (i.e., when the name of an object or a person is known but temporally unavailable), and is lateralized in young adults. It allows us to explore the underlying mechanisms of successful compensation at both intra- and interhemispheric levels . Furthermore, a large literature is emerging on factors that increase the cognitive reserve. The effect of such lifestyle factors (e.g., physical activities, nutrition, socio-cultural activities, and educational level) play at the network level. We thus hypothesize that the functional reorganization of the lexico-semantic processing is a function of the cognitive reserve in normal ageing.

Others activities

HABCO project : The HABCO project, for "HABitudes de vie et fonctionnement COgnitif", aims to developp a numerical environment that encourages people (young and old) to maintain lifestyle activities to preserve a correct level of cognitive functionning. The first step of this project is the creation of a website for the Journée Bien Vieillir 2016 at Lyon (France).
