Topic: respiration-brain phase synchronization

Respiration-entrained neural activities have been theorized to play an integral part in perceptual processing. Given that breathing is a flexible process and can be partly controlled voluntarily, these distinct features may provide a window into how brain-respiration interactions coordinate visual perception. In this study, participants’ breathing was paced at a normal or slow rate while concurrently discriminating fearful from neutral expressions presented during ongoing inspiration or expiration. Behavioral results showed that slow-paced breathing relative to normal-paced breathing decreased
