A post hoc analysis found that the effect of transcutaneous auricular vagus nerve stimulation (taVNS) on cardiac and inflammatory stress responses was critically dependent on variability in baseline ...

Heart rate variability (HRV) measures the fluctuations in time between heartbeats. While it isn’t a health metric you need to overthink, HRV is an indicator of how well the body can adapt to and ...

"Our findings are the first identification of a potential autonomic marker for, and implicating the role of specific neurobiological processes in, agitation propensity in Alzheimer’s disease…It would ...

Participants were required to remember the balloon colour patterns and determine whether each new picture matched the previous one or was different. The experiment included six levels of difficulty. A ...

It’s been known for decades that heart rate variability (HRV) during labor signals how a fetus is responding to stress. Lower HRV—a lower variation in heartbeats—is even a risk factor for sudden ...

Playing music has long been a way for expectant parents to connect with their children in the womb, but a group of researchers has found evidence it can calm fetal heart rates, potentially providing ...
