Description
Adam Wright and colleagues validated a method in 2026 for reading heart and breathing pulses in the brain from slow MRI scans. Brain fluid movement rides on cardiac and respiratory pulsations, yet many dynamic scans sample too slowly to resolve them directly.
Their TRACC-PHYSIO framework lines up recorded heart and breathing waveforms with scan data through time-shifted correlation, yielding coupling strength and pulse delay measures that matched spectral benchmarks with correlations above 0.90. Brain imaging teams gain a way to study neurofluid pulses in ordinary slow scans without faster hardware.
