IAH Seminar - Autonomic nervous system response to extreme environmental conditions

Location: Great Gable Meeting Room, Clinical Ageing Research Unit, Campus for Ageing and Vitality
Time/Date: 27th September 2012, 12:15 - 13:00

You are invited to the IAH research seminar which will take place on Thursday 27 September 2012 in the Great Gable meeting room of the Clinical Ageing Research Unit. The meeting will start at 12.15 and will be followed at approximately 13.00 by a sandwich lunch.

The presentation today will be given by Dr Pawel Zalewski, Nicolaus Copernicus University, Ludwik Rydygier Collegium Medicum, Bydgoszcz, Poland and the title of his talk will be 'Autonomic nervous system response to extreme environmental conditions'.


Autonomic nervous system (ANS) represents complex neuronal network which is vital for the maintenance of homeostasis and reflective functional regulation of most organs. Function of cardiovascular, alimentary, and urogenital systems, thermoregulation, and control of circadian rhythms are tightly controlled by many ANS structures.

Effective functioning of ANS is one prerequisite of homeostasis; ANS is characterized by quick, rapid reflective response to extrinsic and intrinsic stimuli. Currently, several methods are proposed to objectively assess autonomic functions. Most reliable and safe for the examined subjects are modern non-invasive techniques which record data in a beat-to-beat mode.

Human body exposure to extreme environmental conditions has a significant influence on cardiovascular parameters through the autonomic regulation. In this presentation we demonstrate results of scientific research projects on human body exposure to: very low or high ambient temperatures (range from - 120 oC up to 100 oC); hyperbaric conditions which are present at 60 m underwater level; 35-37 hours sleep deprivation.

Biological signals data has been collected in context of cardiovascular and autonomic and also thermoregulation parameters. Results show a rapid adjustment of human autonomic functions in response to extreme condition exposure.
