Motivational Deficits during Goal-Directed Behavior Following Amygdala Inactivation

(A) Increase in fixation error rate before saccade target appeared: fixation breaks (left) and no fixation trials (right).

(B) Earlier termination of the visually guided saccade task following amygdala inactivation. The stopping time was defined as the point at which the monkey failed to make the initial fixation on five consecutive trials over the course of an injection session. When no such sequence of failures occurred, the end of planned experimental session was taken as the stopping time (monkey S: 364.25 ± 49.30 min, monkey D: 131.29 ± 79.74 min in the control session). Each marker indicates the stopping time in each injection experiment (red: monkey S, blue: monkey D). Error bars show SEM; asterisks (∗) and (∗∗∗) indicate statistically significant contrasts at p < 0.05 and p < 0.001. related to Figure 1.
