Abstract
Mental status tasks influence several neurophysiological measures. Biomedical instrumentation is widely used to measure the behavior of the human body and calculate the relative physiological responses to cognitive tasks. There is a common connection between heart rate variability (HRV) and ANS activity. In addition, the skin conductance peak characteristics (SC) from electrodermal activity (EDA) and skin temperature (SKT) modifications can also affect ANS activity As such, the autonomic nervous system (ANS) can easily influence depression. Previous efforts to study and apply HRV features as biomarkers of depression are encouraging. This study includes HRV analysis and temperature measurements during a depression task and is designed to explore the connection between electrocardiography (ECG) and body temperature. Regarding HRV analysis, previous research has shown a decrease in high-frequency (HF) features, as well as body temperature decreases during the day, in patients with depression. Five healthy college students with no health issues participated in the study. An ECG was recorded while relaxing and while performing the Stroop Color-Word task; body temperatures were recorded periodically. Results showed that there were six significant relationships between HRV features and body temperature associated with depression. In addition, short-term meditation had a positive influence, and this protocol could be useful in depressive disorders. Disciplinary: Biomedical Instrumentation, Signal Processing, Mental Disorder.
