Description du projet
Création par notre cerveau de prédictions sur les dynamiques en train de se produire
Le cerveau humain est capable de traiter les informations rapidement. Mais comment gère-t-il un flux d’entrées dynamiques? La transmission et le traitement des informations le long de la hiérarchie du système visuel prend du temps. Alors que les théories du traitement prédictif partent du principe qu’il existe une représentation interne des états externes futurs, la nature représentationnelle des prédictions demeure en grande partie inexplorée. Fort du soutien du programme Actions Marie Skłodowska-Curie, le projet PredictiveBrain étudiera la riche dynamique du traitement prédictif en termes de représentations neuronales.
Objectif
To successfully navigate our dynamic environment, our brain needs to continuously update its representation of external information. This poses a fundamental problem: how does the brain cope with a stream of dynamic input? It takes time to transmit and process information along the hierarchy of the visual system. Our capacity to interact with dynamic stimuli in a timely manner (e.g. catch a ball) suggests that our brain generates predictions of unfolding dynamics. While predictive processing theories assume an internal representation of future external states, empirical research typically employs neural measures that capture an indirect consequence of prediction. The representational nature of predictions remains largely unexplored. One approach for investigating neural representations is representational similarity analysis (RSA), which typically uses models of static stimulus features at different hierarchical levels of complexity (e.g. color, shape, category, concept) to investigate how these features are represented in the brain. I have recently developed a novel dynamic extension to RSA that uses temporally variable models to capture neural representations of dynamic stimuli. A proof-of-concept MEG study unveiled predictive neural representations of naturalistic dynamic input. These promising initial results open the door for addressing important outstanding questions on how our brain represents and predicts the dynamics of the world.
In this project I aim to answer these questions. I will execute the project at the prestigious Donders Institute in the lab of Floris de Lange, a leading expert in the field of predictive processing. The proposed project is unique as it tackles the rich dynamics of predictive processing in terms of neural representations. It will allow me to conduct creative, original and important research, which will propel my scientific career, and strengthen my competitiveness as a scientist.
