دراسة على الفئران تبين أن التنفس البطيء يقلل القلق دون الحاجة إلى اليقظة الذهنية

أظهرت دراسة جديدة أن إبطاء معدلات التنفس يمكن أن يقلل من السلوكيات المرتبطة بالقلق حتى دون أي جهد واعٍ أو إيمان بفاعليتها. وقد استخدم الباحثون الفئران لتوضيح أن الفوائد تنبع من تغييرات فسيولوجية وليس من أثر وهمي. وعُرضت النتائج في قمة عُقدت في لوس أنجلوس في وقت سابق من هذا الشهر.

قدم جاك فيلدمان، وهو عالم أعصاب في جامعة كاليفورنيا في لوس أنجلوس (UCLA)، البحث في قمة "العقول المتجسدة" (Embodied Minds Summit) في لوس أنجلوس في 3 مايو. وقام فريقه بتدريب الفئران على التنفس بشكل أبطأ باستخدام علم البصريات الوراثي، مستهدفين الخلايا العصبية في مجمع "pre-Bötzinger"، وهي منطقة في جذع الدماغ تتحكم في إيقاع التنفس. وبعد أربعة أسابيع، حافظت الفئران على تنفس أبطأ وأظهرت خوفاً أقل في اختبارات التوتر مقارنة بالفئران غير المدربة.

Study links brainstem “lateral parafacial” neurons to a form of hypertension in rats

Researchers working with the University of Auckland and Brazil’s University of São Paulo report that neurons in the medulla’s lateral parafacial (pFL) region—best known for helping drive forceful exhalations—also amplify sympathetic nerve activity and can raise blood pressure in an animal model of neurogenic hypertension. Inhibiting these neurons lowered blood pressure toward normal in hypertensive rats, findings published in Circulation Research.

24-minute music session reduces anxiety in clinical trial

A randomized clinical trial found that 24 minutes of specially designed music paired with auditory beat stimulation significantly lowers anxiety symptoms. Researchers at Toronto Metropolitan University tested various listening durations on 144 adults with moderate anxiety. The 24-minute session provided the strongest benefits.

Fear of aging linked to faster biological aging in women

26 فبراير، 2026 من إعداد الذكاء الاصطناعي

New research from New York University indicates that anxiety about growing older, particularly concerns over health decline, correlates with accelerated cellular aging in women. The study, involving 726 participants, used epigenetic clocks to measure biological aging rates. Fears related to appearance or fertility showed no similar connection.

A new study in Gastroenterology connects early life stress to long-term gut issues through disruptions in gut-brain communication. Mouse experiments and large human cohorts show links to pain, constipation, and irritable bowel syndrome. Researchers suggest targeted treatments based on specific biological pathways.

ADHD brains show sleep-like activity even while awake

17 مارس، 2026 من إعداد الذكاء الاصطناعي

Researchers at Monash University have found that adults with ADHD experience more frequent episodes of sleep-like brain activity during wakefulness, which correlates with attention lapses. The study, published in the Journal of Neuroscience, links these brief shifts to errors, slower reactions, and increased sleepiness during tasks. Lead author Elaine Pinggal suggests this mechanism underlies attention difficulties in ADHD.
