Memory for real-life events: how do contextual associations modulate high-order brain dynamics?

Cognitive Sciences - 2018

This project is constituted of a three-way Sino-French cooperation, including three PIs (Kwok, Abry, and Macaluso) at three different institutes (ECNU, ENS de Lyon, and Uni. Lyon 1).

Goal and significance

We intend to combine neuroimaging techniques (Kwok and Macaluso) and advanced neural data analytical tools (Abry) to quantify temporal information embedded in real-life events to characterize the “higher-order” semantic structure in our episodic memory.

Agenda and project description

Episodic memories are made as we go about our daily life: what event has happened, with whom, where and when. The proposed Incubating Project (new project) for JORISS 2017 will involve looking at novel contexts, including triggering episodes in the real-life of the participants using mobile phone technology (ongoing projects of Macaluso at Lyon 1) and studying the interaction between different kinds of temporal-order memory (ongoing projects of Kwok at ECNU).

The project will target mechanisms of episodic memory retrieval in life-like conditions. The research methodology will include advanced functional imaging methods [effective connectivity and multivariate analyses, see Abry (Abry & Didier, 2018; Wendt, Didier, Combrexelle, & Abry, 2017)], electroencephalogram (EEG), as well as transcranial magnetic stimulation. The main notion is that in real-life conditions different episodes/events are not independent, but are connected in a meaningful manner. For example, if a friend sends me an SMS saying that we should meet at the train station (event 1) and then I see him in front of the station (event 2) these two events are coupled. One could think about many other different types of “event-coupling” (e.g., different stages/missions in a video-game). We aim to formulate formal ways of representing these links, which would then allow us to search for the corresponding neural correlates in the brain (e.g., our recent work: (Fagioli & Macaluso, 2016; Macaluso & Ogawa, 2017; Santangelo, Di Francesco, Mastroberardino, & Macaluso, 2015; Ye et al., 2017).
