Theme of the presentation
• Understanding the underlying physiology of
  stress is useful in managing it.
• “If our brain was simple enough for us to
  understand, we would be too dumb to
  understand it”

What is Stress?
• Stimulus                     • Response
     –   Work                    – Physiological
     –   Time                       •   Autonomic
                                    •   Central
     –   People
                                    •   Endocrine
     –   Conflicting demands

Interactional Models of Stress
•   Perception/appraisal
•   Physiological Mediators
•   Phenomenological experiences
•   Responses

Nature of Modern Stressors
• Few require massive mobilization
  (fight/flight)
• Most involve interpersonal challenges,
  social hierarchies, rejection/acceptance
• Often characterized by internal rumination
  and worry states; anticipatory anxiety
• Strong involvement of negative or critical
  self-judgement

Physiology of Stress
• Four most important systems:
     – Sympathetic Nervous System/Adrenal Medullary
       system
            • Fight/Flight/Fright
     – Parasympathetic Nervous System
            • Rest/Digest
     – Hypothalamic Pituitary System
            • Cortisol
     – Respiratory System
            • Hyperventilation

Parasympathetic (PSNS) Activity
• Parasympathetic activity:
     – Decreases heart rate, polarizes cells.
     – Acts through acetylcholine, high turnover in
       cells means beat-to-beat regulation.
     – Acts to stabilize the cardiac membrane and re-
       establish homeostasis.
     – Usually exceeds SNS activity.

Vagal Withdrawal: An alternative

         Cardiac vagal tone: a physiological index of stress.

         Porges SW.

         Institute for Child Study, University of Maryland, College Park 20742, USA.

         Cardiac vagal tone is proposed as a novel index of stress and stress vulnerability in
         mammals. A model is described that emphasizes the role of the parasympathetic
         nervous system and particularly the vagus nerve in defining stress. The model
         details the importance of a branch of the vagus originating in the nucleus ambiguus.
         In mammals the nucleus ambiguus not only coordinates sucking, swallowing, and
         breathing, but it also regulates heart rate and vocalizations in response to stressors.
         In mammals it is possible, by quantifying the amplitude of respiratory sinus
         arrhythmia, to assess the tonic and phasic regulation of the vagal pathways
         originating in the nucleus ambiguus. Measurement of this component of vagal tone
         is proposed as a method to assess, on an individual basis, both stress and the
9/11/2007vulnerability to stress.                                                              24

“As a consequence of hyperventilation,
the decrease in PCO2 will reduce the
caliber of the arteries and thereby
impede the flow of blood to body tissue
(ischemia), and the increase in blood pH
will reduce the amount of oxygen that
hemoglobin can release to the body
tissue (hypoxia). Therefore, the heart
must pump more frequently and with
greater vigor in order to compensate for
the decrease in pCO2 and increase in
pH.” { Ley, 1987, p.309}

    Vagal Withdrawal: Analternative to Sympathetic Activation • .: Neurosci Biobehav Rev. 1995 Summer;19(2):225-33. – Cardiac vagal tone: a physiological index of stress. Porges SW. Institute for Child Study, University of Maryland, College Park 20742, USA. Cardiac vagal tone is proposed as a novel index of stress and stress vulnerability in mammals. A model is described that emphasizes the role of the parasympathetic nervous system and particularly the vagus nerve in defining stress. The model details the importance of a branch of the vagus originating in the nucleus ambiguus. In mammals the nucleus ambiguus not only coordinates sucking, swallowing, and breathing, but it also regulates heart rate and vocalizations in response to stressors. In mammals it is possible, by quantifying the amplitude of respiratory sinus arrhythmia, to assess the tonic and phasic regulation of the vagal pathways originating in the nucleus ambiguus. Measurement of this component of vagal tone is proposed as a method to assess, on an individual basis, both stress and the 9/11/2007vulnerability to stress. 24

    “As a consequenceof hyperventilation, the decrease in PCO2 will reduce the caliber of the arteries and thereby impede the flow of blood to body tissue (ischemia), and the increase in blood pH will reduce the amount of oxygen that hemoglobin can release to the body tissue (hypoxia). Therefore, the heart must pump more frequently and with greater vigor in order to compensate for the decrease in pCO2 and increase in pH.” { Ley, 1987, p.309} 9/11/2007 29
