كشفت دراسة جديدة عن وجود تفسير ميكانيكي لمتلازمة التعب المزمن (ME/CFS)، يكمن في ضعف وظيفة الجهاز الغليمفاوي المسؤول عن تنظيف الدماغ من النفايات السامة. وأظهرت النتائج أن "ضبابية الدماغ" مرتبطة بضعف إزالة النفايات، خاصة في النصف الأيمن من الدماغ.
Research presented at a neuroscience conference suggests speaking multiple languages can make the brain appear significantly younger. Those speaking four languages had brains appearing up to 13 years younger than monolinguals, with earlier acquisition and higher proficiency showing greater benefits.
Nike's new 'Mind' shoes, based on neuroscience, have gained global attention for their ability to reduce mental distractions and enhance focus. Featuring 22 foam nubs that stimulate nerve receptors, they aim to activate the brain's sensorimotor network and reduce default mode network activity, promoting a state of 'calm alertness'. While experts see scientific logic, they also note potential long-term adaptation and the distinction from traditional wearable tech.
オーストラリアの研究者らが発表した論文によると、銅化合物Cu(ATSM)がアルツハイマー病マウスの血液脳関門の機能を修復し、アミロイドβを42%減らし、記憶力を44%向上させた。既に他の神経疾患で安全性試験が進んでおり、実用化が期待される。
Des chercheurs américains ont réussi à reproduire les bienfaits du sommeil lent sur des souris en stimulant une partie de leur cerveau tout en restant éveillées. Cette technique, inspirée par les dauphins et les canards, pourrait potentiellement être testée sur les humains pour améliorer la récupération et la mémoire.
"Just as we must be responsible for our bodies in an era of office work, we must now keep our minds active," says Jamil Zaki, director of the Stanford Social Neuroscience Lab.
Sleep experts explain that vivid dreams during restless nights are not a sign of increased dream production but rather a failure of the brain's forgetting mechanism. When sleep is interrupted, particularly during REM sleep, the brain fails to delete dream memories before waking, allowing fragments to be encoded into conscious memory. The phenomenon explains why bad dreams feel so real — the prefrontal cortex, which provides logical context, is offline during REM sleep.
