Researchers found that higher levels of oxidative stress biomarkers, including glutathione and specific proteins, were linked to more severe stereotypies in young mice. ]]> 113759 https://neurosciencenews.com/lactate-bdnf-exercise-brain-29724/ Tue, 23 Sep 2025 15:13:43 +0000 https://neurosciencenews.com/?p=112963 A new study shows that the brain benefits of exercise may be partly replicated with an IV infusion of lactate, the by-product of intense physical activity. Researchers found that such infusions increased pro-BDNF levels in the blood—molecules linked to brain growth and resilience—without requiring exercise. ]]> 112963 https://neurosciencenews.com/unnhappiness-hump-depression-aging-29629/ Thu, 28 Aug 2025 12:35:12 +0000 https://neurosciencenews.com/?p=112498 A new large-scale study finds that the long-observed “unhappiness hump,” where mental distress peaked in midlife, has disappeared. Instead, younger people now report the highest levels of anxiety, depression, and stress, with ill-being declining across the lifespan. ]]> 112498 https://neurosciencenews.com/anxiety-insomnia-cannabis-29628/ https://neurosciencenews.com/anxiety-insomnia-cannabis-29628/#comments Wed, 27 Aug 2025 20:34:26 +0000 https://neurosciencenews.com/?p=112494 A new study suggests cannabis-based medical products may help people with insomnia sleep better over the long term. Across 124 patients followed for up to 18 months, participants consistently reported improved sleep quality, less anxiety and depression, and a better overall quality of life. ]]> https://neurosciencenews.com/anxiety-insomnia-cannabis-29628/feed/ 1 112494 https://neurosciencenews.com/childhood-trauma-social-distress-29462/ https://neurosciencenews.com/childhood-trauma-social-distress-29462/#comments Tue, 15 Jul 2025 15:00:06 +0000 https://neurosciencenews.com/?p=111649 A new study reveals that childhood emotional trauma increases social avoidance and distress in adolescents, but resilience can help mitigate these effects. Surveying 577 junior high students, researchers found resilience acted as a buffer, enabling traumatized teens to engage more positively with peers. ]]> https://neurosciencenews.com/childhood-trauma-social-distress-29462/feed/ 1 111649 https://neurosciencenews.com/nightmares-lactose-intolerance-29379/ Tue, 01 Jul 2025 14:21:20 +0000 https://neurosciencenews.com/?p=111314 A new study links lactose intolerance and food sensitivities to disrupted sleep and frequent nightmares. Researchers surveyed over 1,000 students and found that those with dairy intolerance reported more vivid and disturbing dreams, likely due to nighttime gastrointestinal discomfort. ]]> 111314 https://neurosciencenews.com/personality-perception-athletics-29157/ Thu, 29 May 2025 14:44:26 +0000 https://neurosciencenews.com/?p=110461 A new study of Japanese undergraduates finds that students' perceptions of their own athletic ability are shaped by a mix of personality traits, childhood environment, and social feedback. Those who rated themselves as more athletic also tended to display grit, resilience, and a growth mindset. Factors like early walking age, athletic parents, frequent sports participation, and being called athletic by others were also linked to higher self-ratings. ]]> 110461 https://neurosciencenews.com/language-vision-color-memory-28991/ Tue, 20 May 2025 21:15:59 +0000 https://neurosciencenews.com/?p=110199 A new study shows that our ability to recall details about familiar objects—like a banana’s typical color—depends on strong connections between visual and language-processing areas of the brain. Researchers found that stroke patients with disrupted neural pathways between these regions had weaker object-color knowledge and altered brain activity. ]]> 110199 https://neurosciencenews.com/empathy-group-individual-28849/ https://neurosciencenews.com/empathy-group-individual-28849/#comments Thu, 08 May 2025 13:59:35 +0000 https://neurosciencenews.com/?p=109638 People are more likely to choose to empathize with groups rather than individuals, even though they find empathizing equally difficult in both scenarios. Using a card-based empathy selection task, participants opted to empathize 53% of the time when shown groups, versus just 34% for individuals. Researchers suggest that groups provide more contextual information, making empathizing feel more intuitive or meaningful. ]]> https://neurosciencenews.com/empathy-group-individual-28849/feed/ 1 109638 https://neurosciencenews.com/out-of-body-experience-consciousness-28814/ https://neurosciencenews.com/out-of-body-experience-consciousness-28814/#comments Mon, 05 May 2025 12:59:35 +0000 https://neurosciencenews.com/?p=109494 Out-of-body experiences (OBEs) are often dismissed as hallucinations or brain malfunctions, but a new study gives voice to those who have lived them. Through in-depth interviews, participants described their OBEs as vivid, often peaceful, and undeniably real—sometimes more real than waking life. ]]> https://neurosciencenews.com/out-of-body-experience-consciousness-28814/feed/ 3 109494 https://neurosciencenews.com/intent-action-neuroscience-28668/ Fri, 18 Apr 2025 12:20:49 +0000 https://neurosciencenews.com/?p=108870 A groundbreaking study used a brain-machine interface to explore how intentions, actions, and their outcomes are temporally linked in the human brain. By recording single-neuron activity from a paralyzed individual with implanted electrodes, researchers enabled intentional hand movement through machine-learning-driven muscle stimulation. ]]> 108870 https://neurosciencenews.com/purkinje-cells-tongue-movement-28597/ Thu, 10 Apr 2025 20:35:38 +0000 https://neurosciencenews.com/?p=108594 Researchers studying marmosets discovered that Purkinje cells in the cerebellum help regulate tongue movement by signaling when to stop as the tongue nears its target. These cells were highly engaged during precision tasks, like inserting the tongue into narrow tubes, but not during casual grooming. ]]> 108594
