The probability by risk-taking interaction was significant in dorsolateral PFC [ F (1,37) = 3.89, P = 0.05] and marginally significant in ventral striatum [ F (1,37) = 3.86, P = 0.057].
The probability by risk-taking interaction was significant in dorsolateral PFC [ F (1,37) = 3.89, P = 0.05] and marginally significant in ventral striatum [ F (1,37) = 3.86, P = 0.057].
In ventral striatum, a three-way group by probability by hemisphere interaction approached significance [ F (1,38) = 3.81, P = 0.058], which indicated that in left ventral striatum, the increase in activity for high-probability rewards (relative to low) was more pronounced in the bipolar disorder compared to healthy control group.
Although in the direction hypothesized, the probability by impulsivity interactions failed to reach significance in dorsolateral PFC ( P = 0.07) and ventral striatum ( P = 0.13).
