Brain correlates of autonomic modulation: Combining heart rate variability with fMRI (2008, methodology): “Other studies have attempted to correlate HR or MAP with fMRI (Kimmerly et al. 2005) or PET (Critchley et al. 2000).”
Human cingulate cortex and autonomic control: converging neuroimaging and clinical evidence. (2003, background): “Activity in adjacent regions of the medial and orbital prefrontal cortex has previously been associated with increased HRV (re ̄ecting decreased sympathetic activity) in a PET study of induced emotional states (Lane et al., 2001).”
Brain mediators of cardiovascular responses to social threat, Part I: Reciprocal dorsal and ventral sub-regions of the medial prefrontal cortex and heart-rate reactivity (2009, result): “If the dorsal and ventral MPFC are relatively specialized for sympathetic and parasympathetic control, respectively, as previous analyses have suggested (Gianaros et al., 2004; Lane et al., 2001), then we might expect the first case.”
Claude Bernard and the heart-brain connection: further elaboration of a model of neurovisceral integration. (2009, unknown): “Specifically, we have shown in a series of studies using both pharmacological and neuroimaging approaches that prefrontal cortical activity is associated with vagally mediated HRV (Ahern et al., 2001; Lane et al., 2001, 2007, 2008; Nugent et al., 2007, 2008).”
