Figure 2From: Evidence for impulsivity in the Spontaneously Hypertensive Rat drawn from complementary response-withholding tasksLHT efficiency. Mean efficiency in LHT ± SEM as a function of target time T. Efficiency was computed as the proportion of durations longer than T. For T > 1 s, LE rats were substantially more efficient than SHR and WKY rats.Back to article page
