Perceptual and Attentional Fluctuations (PAF)

Head : Rufin VANRULLEN

Our team focuses on the dynamic (fluctuating) nature of sensory perception, attention and higher cognitive functions. How do these functions unfold from moment to moment ? How is a percept, or a thought, constructed upon its immediate perceptual history ? Do perceptual and attentional fluctuations also take place on an even faster timescale, entrained by cortical oscillations ? At the other end of the spectrum, what can we learn from fluctuations caused by individual differences in sensory and cognitive functions ? These questions are addressed using a unique multi-scale approach, from in-vivo intracellular recordings and optical imaging to human EEG and fMRI.

Key words : electrophysiology, integrative neuroscience, multistability, synesthesia, oscillations, perceptual cycles, meditation, mind-wandering
