Perceptual consciousness
Michael Pereira
SNSF Postdoc Mobility fellow
I am a postdoctoral researcher in cognitive neurosciences studying the neural mechanisms of perceptual consciousness and metacognition with psychophysics and computational modelling in healthy individuals as well as invasive electrophysiology with psychiatric and neurological patients. My goal is to find a mechanistic explanation of how single neurons in the human brain explains the fluctuations of our subjective perceptual experience within a single trial. I am currently hosted at the Laboratoire de Psychologie et NeuroCognition by Dr. Nathan Faivre, funded by the Swiss National Science Foundation.

A leaky evidence accumulation process for perceptual experience
The neural correlates supporting our perceptual experience of the world remain largely unknown. Recent studies have shown how stimulus …

A fundamental scientific question concerns the neural basis of perceptual consciousness and perceptual monitoring resulting from the …
Increased functional connectivity of the intraparietal sulcus underlies the attenuation of numerosity estimations for self-generated words
Previous studies have shown that self-generated stimuli in auditory, visual, and somatosensory domains are attenuated, producing …
