No Evidence For Modulation Of The Readiness Potential By Respiratory Phase During Natural Breathing, Lucas Jeay-Bizot, Raniyah Chisti, Uri Maoz, Aaron Schurger

Psychology Faculty Articles and Research

Respiratory processes are increasingly implicated in shaping neural activity and behavior. Recent studies have reported a coupling between respiratory phase and the cortical readiness potential (RP), suggesting that breathing may modulate the neural processes preceding voluntary action. Here, using electroencephalography recordings in humans, we re-examine this claim using the original dataset and a new independent dataset, as well as in simulated data with no coupling. We show that the reported association arises from a confound: both RP amplitude and respiratory phase are coupled to movement onset. The original analysis does not control for this dependency, leading to a spurious effect …
