Scientists identify a specific neural switch that can be "turned on" to help the brain unlearn fear and trauma faster than ever.]]> https://neurosciencenews.com/unlearning-fear-crf-bnst-30196/feed/ 0 114998 https://neurosciencenews.com/astrocytes-fear-memory-amygdala-30159/ https://neurosciencenews.com/astrocytes-fear-memory-amygdala-30159/#respond Fri, 20 Feb 2026 17:45:16 +0000 https://neurosciencenews.com/?p=114830 Star-shaped astrocytes have been unmasked as the master controllers behind how your brain learns—and unlearns—fear.]]> https://neurosciencenews.com/astrocytes-fear-memory-amygdala-30159/feed/ 0 114830 https://neurosciencenews.com/ptsd-brain-aging-30026/ Mon, 08 Dec 2025 18:24:20 +0000 https://neurosciencenews.com/?p=114280 A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on more than 11,000 MRI scans, researchers found that responders with PTSD had “older” appearing brains than those without the disorder, especially among individuals with longer exposure at Ground Zero. ]]> 114280 https://neurosciencenews.com/music-nature-mental-health-29858/ Sun, 26 Oct 2025 19:48:13 +0000 https://neurosciencenews.com/?p=113565 The viral phrase “touch grass” may be more than internet humor—science shows that engaging with nature and music can significantly boost emotional and physical well-being. A new review found that combining these experiences—such as listening to music outdoors, gardening while singing, or caring for animals—can improve mood, reduce stress, and ease symptoms of anxiety and depression. ]]> 113565 https://neurosciencenews.com/fear-memory-extinction-29658/ https://neurosciencenews.com/fear-memory-extinction-29658/#comments Wed, 03 Sep 2025 17:19:44 +0000 https://neurosciencenews.com/?p=112630 Scientists have, for the first time, identified the brain signals linked to extinguishing fear memories in humans. Using implanted electrodes and advanced Representational Similarity Analysis, they showed that theta activity in the amygdala increases when previously unpleasant cues are re-learned as safe. ]]> https://neurosciencenews.com/fear-memory-extinction-29658/feed/ 2 112630 https://neurosciencenews.com/hormonal-contraceptives-memory-emotion-29638/ Fri, 29 Aug 2025 18:30:16 +0000 https://neurosciencenews.com/?p=112540 A new study reveals that hormonal contraceptives may shape both emotional responses and memory processing in women. Compared with naturally cycling women, users of hormonal birth control had stronger emotional reactions and remembered fewer details of negative events when using regulation strategies like distancing or reinterpretation.]]> 112540 https://neurosciencenews.com/brain-map-stress-social-behavior-29625/ Wed, 27 Aug 2025 16:15:26 +0000 https://neurosciencenews.com/?p=112476 A new study has identified a key brain hub in the medial prefrontal cortex that regulates stress responses and social behavior, offering critical insights into psychiatric conditions. Using advanced imaging and AI mapping in mice, scientists charted how these regions integrate sensory and bodily signals to control emotional stability. ]]> 112476 https://neurosciencenews.com/mental-health-sensitivity-29587/ Sat, 16 Aug 2025 16:03:12 +0000 https://neurosciencenews.com/?p=112269 A large-scale meta-analysis of 33 studies has shown that highly sensitive individuals are more prone to common mental health problems, including depression, anxiety, PTSD, and avoidant personality disorder. Sensitivity was defined as a heightened responsiveness to environmental and emotional cues, making people more vulnerable but also more receptive to positive experiences and therapy. ]]> 112269 https://neurosciencenews.com/glial-cells-ptsd-29543/ Fri, 01 Aug 2025 12:46:12 +0000 https://neurosciencenews.com/?p=112041 A new study reveals that astrocyte-derived GABA, not neuronal activity, plays a central role in PTSD by impairing the brain’s ability to extinguish traumatic memories. Researchers found this excess GABA originates from the enzyme MAOB in astrocytes and disrupts fear regulation in the medial prefrontal cortex. ]]> 112041 https://neurosciencenews.com/fear-pain-ptsd-imprinting-29525/ https://neurosciencenews.com/fear-pain-ptsd-imprinting-29525/#comments Fri, 25 Jul 2025 19:40:09 +0000 https://neurosciencenews.com/?p=111944 A new study reveals that even after healing, injuries can leave behind a hypersensitive nervous system that overreacts to future stress. Mice previously injured showed intense fear and renewed pain when exposed to a predator scent, despite no new harm. ]]> https://neurosciencenews.com/fear-pain-ptsd-imprinting-29525/feed/ 1 111944
