Being an homeostatic controller is expected that the autonomic nervous system would show a degree of impairment in lead toxicity.

Lately, heart rate variability (HRV) and blood pressure adaptations have been studied in relation to Space Exploration. Most data obtained so far, indicate a decrease in heart rate (HR), mainly explained by a decrease in the low frequency component (LF) of HRV and an increase in the high frequency band (HF), indicating a predominant vagal modulation during space flights. In order to validate our laboratory...
