ODE parameters for SCR			Gaussian parameters for SN
Parametera	Aversive	Oddball	Parameterb	Aversive	Oddball
ϑ1	1.3277	1.5457	µ	1.6850	1.6785
ϑ2	1.1205	1.9595	σ	0.3051	0.2471
ϑ3	0.1084	0.1336	A	0.7814	0.6589
ϑ4	−0.4265	0.3001	c	0.1567	0.0000

^aϑ1–ϑ₃ determine the shape of the SCRF. ϑ₄ determines the delay with respect to an eliciting SN burst and depends on the precise distance of the intraneural recording electrode from the skin; hence, it has no generalizable interpretation.

^bσ describes the shape (dispersion) and µ the delay of an SN burst with respect to an eliciting external stimulus. Delay depends on recording location along the nerve. A is the amplitude, which depends on recording settings, and c is the baseline SN activity.
