Mental Mapping of Time and Space

We are not stuck in the immediate present but often wander along memories or future plans. Neural 
and behavioral data suggest that past and future thinking rely on a common set of cognitive operations. Starting from the hypothesis of a spatialization of mental time, I am trying to decipher the relations between the mental representations of time and space with chronometry, fMRI and MEG/EEG.

Our first work shows through a series of behavioral studies that mental time travel and mental space navigation undergoes two similar cognitive operations: self-projection and egocentric distance calculations. These operations allow the human mind to set egocentric cognitive maps
. These mental maps seems distinct for time and space.

Our second study shows that fMRI correlates of self-projection and distance calculations are largely dissociated, although converging in right inferior parietal lobule. A confirmation for distinct cognitive maps but common computations.

Our latest work pertains the temporal dynamics of setting and maintainting egocentric cogntive maps across real time with the help of combined MEG/EEG. Particularly, ordinal relations differ between temporal and spatial representations.

Episodic Autobiographical Memory

Autobiographical memories (AM) are self-related memory of life events and such memories present interesting and specific subjective properties. In my newest line of research, I am investigating the formation of AM using latest virtual reality tools. More to come about this soon.
