Soehner AM, et al. - Researchers tested bipolar disorder (BD) diagnosis and sleep (duration and variability) as predictors of fronto-limbic response to a stressful cognitive control task among transitional age youth. They observed a hyper-limbic response during cognitive control among subjects with BD, and sleep was a source of variability in amygdala, anterior cingulate engagement. For improving cognitive control in BD, stabilizing sleep could be one avenue.
