“…Importantly, recent theorizing has postulated that HRV might reflect the activity of a central autonomic network, which involves -among other regionsthe anterior cingulate, insular, orbitofrontal, and ventromedial prefrontal cortices (e.g., Lane, 2000, 2009). It has been hypothesized that the prefrontal cortex inhibits amygdala-related regions and medullary cardioacceleratory circuits (Martens et al, 2008;Thayer and Sternberg, 2006). Thus, HRV has been considered to indicate inhibitory activity of the prefrontal cortex.…”
