A. Prior to treatment, percent inhibition of startle response to a short tone following a pre-pulse of 3, 6, 9, or 12 decibels (dB) above background noise (PP3 – PP12) compared to startle with no pre-pulse. B. Following treatment, percent inhibition of startle response to a tone following a pre-pulse 3 decibels above background noise compared to startle with no pre-pulse. One way ANOVA with Tukey’s multiple comparisons test **** p<.0001
