Skin conductance Flashcards
1
Q
What is skin conductance?
A
the use of sweat to measure SNS activity rising to stress
2
Q
What type of sweat glands does skin conductance rely on?
A
eccrine glands
3
Q
Eccrine glands
A
found all over body, primary form of cooling
*cholinergic sympathetic nerves in glands release Ach
4
Q
What is another type of gland (that we don’t measure skin conductance with)
A
apocrine glands
5
Q
apocrine glands
A
in armpits, not primary form of cooling
*adrenergic sympathetic nerves in glands that release NE
6
Q
Formula for conductance
A
C = 1/R
Resistance (R) = V/I
7
Q
Why is skin conductance better than LF frequency?
A
LF frequency also takes parasympathetic into account and this is only SNS
