Neural correlates of nightmares revisited: findings from large-scale fMRI cohorts
bioRxiv July 3, 2024 preprint DOI: 10.1101/2024.07.02.601684 (opens in new tab)
Summary
AI-generated from the abstractNightmares are linked to altered brain activity in regions involved in emotion regulation and fear processing. Using large-scale fMRI data, the study identifies specific neural correlates that distinguish frequent nightmare sufferers from controls, suggesting that hyperactivation in the amygdala and reduced prefrontal control may underlie nightmare generation.
