Alternating Phase Coherence of Spontaneous Hemodynamic Oscillation is Sensitive to Anesthesia Levels

Introduction Coherent fluctuation of blood oxygen level dependent (BOLD) signals has been widely observed in human and animal brains, and it was hypothesized to reflect spontaneous brain activity and reflect a variety of “resting-state” brain networks . Besides positive correlations, negative correlations have also been observed between spontaneous BOLD… CONTINUE READING
