Graphic depiction of the primary findings from the SSRT paradigm displaying impaired behavioral inhibition in the P rats. A) Mean (±SEM) SSRT estimate for each strain. B) Mean (±SEM) p(inhibition) graphed as a function of mGoRT-SSD. *, **, and *** correspond to p<.05, p<.01, and p<.001 using Fischer’s LSD test; #, ‡, and & indicate differences between P vs. HAD2, P vs. LE, and LE vs. HAD2 respectively using Student t tests after Bonferroni correction for multiple comparisons.
