Neuroendocrine response to biologically salient (yap) and standard (noise burst) acoustic startle stimuli

Study 1: Habituation of the startle response to repeated stimuli (test session duration = 17.5 min test)
	Baseline (± SEM)	Post-yap (± SEM)	Change from baseline	Post-noise burst (± SEM)	Change from baseline
Plasma ACTH (pg/ml)	56.52 ± 4.29 ^a	164.43 ± 17.87 ^b	191%	176.91 ± 19.50 ^b	213%
Plasma cortisol (μg/dl)	47.55 ± 10.02 ^a	76.73 ± 5.64 ^b	61%	71.19 ± 7.19 ^b	50%

Study 2: Relationship of the startle response to stimulus intensity (test session duration = 33.5 min test)
	Baseline (± SEM)	Post-yap (± SEM)	Change from baseline	Post-noise burst (± SEM)	Change from baseline
Plasma ACTH (pg/ml)	83.43 ± 10.89 ^a	146.32 ± 15.67 ^b	75%	132.04 ± 13.45 ^b	58%
Plasma cortisol (μg/dl)	126.39 ± 21.07 ^a	267.37 ± 31.03 ^b	112%	231.33 ± 14.63 ^b	83%

Superscripts ^a, ^b = groups with no shared letters differ significantly (p < 0.05).
