From: Timing of vagus nerve stimulation during fear extinction determines efficacy in a rat model of PTSD
Extinction learning is maintained after 7 days of VNS-paired extinction. Rats that received during VNS or continuous VNS showed nearly 50% improvement in extinction recall compared to Sham VNS rats a week after extinction training. Data are represented by the mean ± SEM using the average of the 5 trials from the retention session, and analyzed by on-way ANOVA. *p < 0.05 (Bonferroni’s post hoc test). Sham (n = 11), VNS during (n = 10), VNS between (n = 11), VNS dispersed (n = 9), VNS continuous (n = 11).
