BD-II, euthymic (n = 19)

HC (n = 20)

Behavioral:

Performance in n-back task

Neural:

RT in 2-back without distractors:

BD-I > HC

BD-II vs. HC: NS

RT in the 2-back task (no distractor vs. emotional distractor):

BD-I:

Fear > no distractor

Happy > no distractor

BD-II:

NS

HC:

Fear > no distractor

Neutral > no distractor

2-back (no distractor) vs. 0-back (no distractor):

Working memory network: BD-I > BD-II and HC

2-back task (distractor vs. no distractor):

DLPFC:

Happy: BD-I > BD-II and HC

Neutral: BD-I > HC

Functional connectivity:

DLPFC-Amygdala
