Question

BSR(Basal skin response) gives _____________

(a) activity of sweat glands

(b) baseline value of skin resistance

(c) activity of endrocine glands

(d) baseline value of breathing

This question was addressed to me in a job interview.

Asked question is from Cardiac Arrhythmias in section Arrhythmia and Ambulatory Monitoring Instruments of Biomedical Instrumentation

Answer 1

Correct choice is (b) baseline value of skin resistance

For explanation: BSR (basal skin response) and GSR (galvanic skin response) is a measure of the average activity of the sweat glands and is a measure of the phasic activity (the high and low points) of these glands. BSR gives the baseline value of the skin resistance where as GSR is due to the activity of the sweat glands.
