Aaron Schurger

Aaron Schurger, of the Laboratoire de Psychologie et NeuroCognition at CNRS and Université Grenoble Alpes, produced one of the most consequential reinterpretations in modern consciousness science. The readiness potential, the EEG signal that precedes voluntary movements, was read for decades as the brain’s decision forming before the subject reports deciding, an argument used against free will and for unconscious origins of choice. Schurger’s stochastic accumulator model (PMID 31078047) showed the signal can arise from the leaky accumulation of spontaneous neural noise crossing threshold at unpredictable moments, so the potential reflects fluctuations rather than a completed prior decision.

The critical discipline this imposes is exactly the kind this site’s measurement posts demand. A neural precursor that looks causal may be an artifact of averaging noise-locked trials, and interpretations built on such signals inherit the artifact. His work with Michael Graziano’s group on awareness and error monitoring ties the program to the attention schema tradition.

Schurger’s position, stated through models rather than manifestos, is that consciousness science must survive its own statistics. His profile anchors the site’s coverage of the methods crisis inside the field’s own data.
