Heartbeat timing influences brain's sensory processing, potentially affecting neuroscience research
By
Caroline Williams Author
Summary
A growing body of research suggests that the heartbeat subtly influences how the brain processes sensory information, potentially skewing results in neuroscience experiments that ignore this bodily rhythm. A 2024 NeuroImage study showed participants' brains responded differently to visual stimuli presented at the moment of heart contraction versus between beats, even though participants were unaware of the timing. This phenomenon, called cardiac timing, may affect perception, attention, and memory, raising questions about whether standard neuroscience practices that average data across heartbeats are missing important neural dynamics.
