Should heart rate variability be “corrected” for heart rate? Biological, quantitative, and interpretive considerations
AbstractMetrics of heart period variability are widely used in the behavioral and biomedical sciences, although somewhat confusingly labeled as heart rate variability (HRV). Despite their wide use, HRV metrics are usually analyzed and interpreted without reference to prevailing levels of cardiac chronotropic state (i.e., mean heart rate or mean heart period). This isolated treatment of HRV metrics is nontrivial. All HRV metrics routinely used in the literature exhibit a known and positive relationship with the mean duration of the interval between two beats (heart period): as the heart period increases, so does its variabi...

Don ’t look, don’t think, just do it! Toward an understanding of alpha gating in a discrete aiming task
AbstractPrior to and during movement, oscillatory alpha activity gates cognitive resources toward motor areas of the cortex by inhibiting neuronal excitability in nonmotor areas. The present study examined the effect of manipulating target variability on this alpha gating phenomenon. Using a baseline ‐test‐retention design, we measured EEG alpha power, performance accuracy, and task difficulty in 32 recreational golfers as they putted golf balls (20 per target) to one central target (baseline, retention) and four targets of different directions and extents (manipulation). For participants in the random group (n = 16)...

Heart ‐rate modulations reveal attention and consciousness interactions
We presented near‐threshold visual stimuli th at could be preceded by an alerting tone on 50% of the trials. Behaviorally, phasic alerting improved perceptual sensitivity for detecting a near‐threshold stimulus (along with changes in response criterion). Following the alerting tone, a cardiac deceleration‐acceleration pattern was observed, which was more pronounced when the near‐threshold stimulus was consciously perceived in comparison with unconsciously perceived stimuli. SC results further showed some degree of subliminal processing of unseen stimuli. These results reveal that cardiac activity could be a marker ...

Integrated genetic, epigenetic, and gene set enrichment analyses identify NOTCH as a potential mediator for PTSD risk after trauma: Results from two independent African cohorts
AbstractThe risk of developing posttraumatic stress disorder (PTSD) increases with the number of traumatic event types experienced (trauma load) in interaction with other psychobiological risk factors. The NOTCH (neurogenic locus notch homolog proteins) signaling pathway, consisting of four different trans ‐membrane receptor proteins (NOTCH1 –4), constitutes an evolutionarily well ‐conserved intercellular communication pathway (involved, e.g., in cell–cell interaction, inflammatory signaling, and learning processes). Its association with fear memory consolidation makes it an interesting candidate for PTSD research....

Personal responsibility modulates neural representations of anticipatory and experienced pain
This study investigated how the sense of personal responsibility affected the neural dynamics of anticipating one's own pain and another person's pain, using EEG. Participants played a cooperation game in which either the participant (self‐context) or the confederate (other‐context) received a mild electric shock whenever one of them erred. At the anticipatory stage of pain, feedback‐related negativity (FRN) and P300 were sensitive to the degree of responsibility in both contexts. The FRN was more negative when the participant had full responsibility (only the participant had erred) than when the participant shared r...

Breakthrough percepts of famous faces
AbstractRecently, we showed that presenting salient names (i.e., a participant's first name) on the fringe of awareness (in rapid serial visual presentation, RSVP) breaks through into awareness, resulting in the generation of a P3, which (if concealed information is presented) could be used to differentiate between deceivers and nondeceivers. The aim of the present study was to explore whether face stimuli can be used in an ERP ‐based RSVP paradigm to infer recognition of broadly familiar faces. To do this, we explored whether famous faces differentially break into awareness when presented in RSVP and, importantly, wheth...

Brain correlates of stress ‐induced peripheral vasoconstriction in patients with cardiovascular disease
AbstractThe influence of acute psychological stress on cardiovascular disease is an emerging public health concern. Identification of brain mechanisms underlying this may aid in the discovery of possible treatments. Acute psychological stress may induce arteriolar vasoconstriction and reduce blood flow to vital organs. We hypothesized that functional changes in brain regions involved with memory and autonomic/emotional regulation are implicated in the vasoconstrictive stress response, including the medial prefrontal cortex (anterior cingulate), insula, and dorsolateral prefrontal cortex. Subjects with a history of coronary...
