The Physiological Component of the BOLD Signal: Impact of Age and Heart Rate Variability Biofeedback Training
Richard W. Song, Jungwon Min, Shiyu Wang…·Catie E. Chang
This study examines age-related differences in how cardiac and respiratory fluctuations influence the BOLD signal and shows that HRV-BF training can modulate physiological-BOLD coupling in an age-dependent manner.
