Why the study?

Does resting high-frequency heart rate variability covary with resting state neural activity in the default mode network and salience network in midlife adults?

Structured PICO

Does resting high-frequency heart rate variability covary with resting state neural activity in the default mode network and salience network in midlife adults?

Population

219 midlife adults (52% female) assessed across two studies (Study 1, N=107; Study 2, N=112).

Outcome

Covariation of resting high-frequency heart rate variability (HF-HRV) with resting state neural activity in the default mode network (DMN) and salience network (SN), particularly within the medial prefrontal cortex (mPFC).surrogate

Resting high-frequency heart rate variability is associated with localized functional connectivity in the perigenual anterior cingulate cortex, suggesting a neural basis for autonomic cardiac control.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Does not support broad DMN/SN links to HF-HRV; extends localized perigenual ACC evidence but remains hypothesis-generating.
