Disrupted Fear Regulation in Insomnia Disorder Revealed by Arousal Estimation From Skin Conductance


Associate Professor Rose Faghih and collaborators at Harvard Medical School used skin conductance measurements to investigate differences in fear regulation between 24 adults with insomnia and 24 good sleepers. Their computational analysis found evidence that insomnia may be associated with difficulty learning and remembering that a previously threatening stimulus is no longer dangerous. The findings suggest that physiological arousal measurements could help researchers better understand the relationship between insomnia and anxiety-related conditions.
