Loss, gain and choice difficulty in gambling patients: Neural and behavioural processes.

Thus, larger choice difficulty was stronger associated with higher neural activity in controls compared with patients with GD in the right anterior insula ( t (41) = −2.77, p = 0.008, η 2 p = 0.15, see Figure 4C ), and there was a smaller, almost significant effect in the ACC ( t (41) = −1.88, p = 0.068, η 2 p = 0.12).
