• Reciprocal relationship of the parasympathic and the sympatathetic nervous system only valid if ... (three)

  • Target organs innervated (geprikkeld) by sympathetic and parasympathetic nervous system 
  • Functions of the sympathetic and parasympathetic antagonistic
  • ANS centrally regulated by reciprocal control

• electrodermal activity: EDA

  Skin conductance/-resistance based on change in conductance by sweat secretion

• Three ways how the blood is returning to the heart

  1. Valves (=klepjes) in the veins (low blood pressure) prevent the backflow of blood. 
     
  2. Tone of the skeletal muscles. 
     
  3. Pressure differences in the thoracic cavity. 
     

• 3 forms of ANS control

  
  

  1. Chronotropic (Heart rate) - mostly parasymp
  2. Dromotropic (conduction speed)
  3. Inotropic (contraction strength) –mostly symphatetic 

• Respiratory Sinus Arrythmia 

  During inhalation (inspiration), the heart rates becomes faster. Parasympathetic control. 

• Two reflexes that have a large effect on the pupil size that are not cognitive factors 

  • Pupil light reflex
  • Accommodation reflex

• 5 relationships between the psychological and physiological domain

  • One-to-one
  • One-to-many
  • Many-to-one
  • Many-to-many 
  • No relationship

• Four categories of psychophysiological relationships 

  • Psychophysiological outcomes: An outcome is defined as a many-to-one, situation-specific (context-dependent) relationship between ψ and ϕ. 
    
  • Psychophysiological markers: A psychophysiological marker is defined as a one-to-one, situation-specific (context-dependent) relationship between abstract events ψ and

• There are two forms of sweat glands in the human body

  • Apocrine
    
  • Eccrine: The primary function of most eccrine sweat glands is thermoregulation. However, those located on the palmar and plantar sufaces are thought to be more related to grasping behaviour than to evaporative cooling and they have been suggested to be more responsive to psychologically significant stimuli than to thermal stimuli. 
    

• Upper layer with dead skin cells protecting the body

  Stratum corneum (non conductive)
