Principales activités

Scientific Background. The integration of multimodal data to elucidate the neural processes and networks underlying cognition and behavior is a major challenge in cognitive neuroscience. This is associated with a current paradigm shift, with neurocognitive models that consider that complex interactions between cognitive functions enable human behaviors. The fusion (integration) of multimodal data could not only compensate for the limitations of each modality but also detect features that are intrinsically multimodal.


Objectives and research program. This research work is situated at the interface between language and declarative memory and addresses the question of their interactive union in a multimodal and integrative perspective with artificial intelligence methods. The project will have two dimensions, one neurocognitive and another neurocomputational. On the neurocognitive side, the objective is to validate and enrich this new theoretical framework LM language-union-memory that we have recently developed (Roger et al., 2022) and consists in considering that language and
memory are two inseparable functions and that their evaluation must be done in an interactive joint way, rather than in isolation. The project will also have a trans-cognitive dimension to explore this framework in normal and pathological conditions. On the neuro-computational side, we will use several analysis methods (unsupervised machine learning, graph theory, and deep learning) for multimodal fusion and develop transfer learning in the framework of deep learning AI. Multimodal biomarkers (neuropsychology, functional and anatomical neuroimaging) have been acquired in our previous work.
