Methods of measuring brain and behaviour: ANS measures

4 important questions on Methods of measuring brain and behaviour: ANS measures

What is meant by the autonomic nervous system?

The division of the PNS that governs the internal activities of the human body, including heart rate, breathing, digestion, salivation, perspiration, urination and sexual arousal

Why is skin conductance only measured by Sympathetic NS only?

Electrical conductance  of skin, depends on moisture level. !!! Sweat glands are controlled by sympathetic NS only, typical range = 2-20 micro S(micro SIemens)

 

How to measure? Apply two sensors (bipolar) on two fingers, palms or soles of the feet

What happens during typical sympathetic stimulation?

Arousal is increased sweat production is increased skin conductance

What is meant by heart rate variability?

The degree of variation in the length of the interval between two heart beats

Determined by both sympathetic and parasympathetic stimulation. Multiple HRV measures to split sympathetic and parasympathetic contributions. Based on ECG signal.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
