“…The vagus nerve enables communication between the parasympathetic nervous system (PNS) and the heart. For healthy subjects under resting conditions, power spectral analysis represents the two dominant rhythmic oscillations in the arterial blood pressure heart period fluctuations (Palacios-Garcia et al 2015). The low frequency (LF) component typically concentrates at a frequency of 0.1 Hz, while the high frequency (HF) component, synchronous with respiration, has a central frequency of 0.25 Hz.…”

Complaints of stress are common in modern life. Psychological stress is a major cause of lifestyle-related issues, contributing to poor quality of life. Chronic stress impedes brain function, causing impairment of many executive functions, including working memory, decision making and attentional control. The current study sought to describe newly developed stress mitigation techniques, and their influence on autonomic and endocrine functions. The literature search revealed that the most frequently studied technique for stress mitigation was biofeedback (BFB). However, evidence suggests that neurofeedback (NFB) and noninvasive brain stimulation (NIBS) could potentially provide appropriate approaches. We found that recent studies of BFB methods have typically used measures of heart rate variability, respiration and skin conductance. In contrast, studies of NFB methods have typically utilized neurocomputation techniques employing electroencephalography, functional magnetic resonance imaging and near infrared spectroscopy. NIBS studies have typically utilized transcranial direct current stimulation methods. Mitigation of stress is a challenging but important research target for improving quality of life.

“…However, the power of LF and HF can either be measured in absolute values of power (ms2) or in normalized units (n.u.) whose value can be calculated (Palacios-Garcia et al 2015).…”
