Elementary integrate-and-fire process underlies pulse amplitudes in Electrodermal activity
Fig 1
Schematic of our physiological hypothesis and statistical model simplifications.
(A) We hypothesize that the amplitude of a pulse is related to the excess volume of sweat produced relative to what is required to reach the surface of the skin, which translates to the difference of first passage times between two integrate-and-fire processes, yielding the difference of two inverse Gaussian distributions. (B) We arrived at a series of simplifications of our model based on the statistical properties observed. IG = inverse Gaussian.
