          Why Do Embarrassing Memories Seem to Surface at Night?

          During REM sleep, the locus coeruleus stops releasing noradrenaline. By blocking the cascade, the association between memory and emotional response is broken. This may not occur so frequently in restless sleepers, resulting in rumination and PTSD-like symptoms. For those who usually sleep well, embarrassing feelings experienced at night may be reduced by morning.

          Changes in brain attention may underlie autism

          Those on the autism spectrum had atypically smaller pupil dilation compared to the control group during distracting conditions while taking a push-button test. The findings suggest those with ASD may have dysregulation in locus coeruleus activity. The dysregulation of the LC may explain the exaggerated responses to environmental stimuli and fixated behaviors many with ASD experience.
