From: Confounding effects of heart rate, breathing rate, and frontal fNIRS on interoception
Frontal hemodynamics results. (A) Changes in connectivity induced by the cessation of focusing on heartbeats. (B) Changes in connectivity induced by switching the breathing rate in the breathing rate control task. (C) Changes in the respiratory response in fNIRS with respect to changes in breathing rhythm. Thick white channels indicate significance corrected for multiple comparisons. (D) Exemplary fNIRS signals for one trial of the heartbeats counting and breathing control tasks.
