New method tracking changes in blood vessels could advance brain disease detection（图）
血管变化 脑部疾病 成像技术 神经退行性疾病
2023/6/26
A new imaging technique opens a path toward long-term study of blood vessels in aging brains and could help predict neurodegenerative diseases decades before symptoms begin.
Many of our body’s most important functions occur without our conscious knowledge, such as digestion, heartbeat, and breathing. These vital functions depend on the signals generated by the “interocept...
The following press release was issued today by the Broad Institute of MIT and Harvard.
Our brains are charged with the task of directing most of the processes needed for our bodies to function. As such, they consume roughly 20% of our body’s metabolic energy, even while we’re resting.
Alzheimer’s risk gene undermines insulation of brain’s “wiring”（图）
阿尔茨海默氏症 风险基因 APOE4 脑细胞 隔离神经元
2023/6/21
It’s well-known that carrying one copy of the APOE4 gene variant increases one’s risk for Alzheimer’s disease threefold and two copies about tenfold, but the fundamental reasons why, and what can be d...
Last year, MIT researchers announced that they had built “liquid” neural networks, inspired by the brains of small species: a class of flexible, robust machine learning models that learn on the job an...
What a long, strange trip it’s been for psychedelic drugs. From their use in ancient indigenous ceremonies, to their often-caricatured association with the 1960s counterculture, to their recent reemer...
Engineers develop nanoparticles that cross the blood-brain barrier（图）
血脑屏障 纳米颗粒 胶质母细胞瘤 化疗药物
2023/6/19
There are currently few good treatment options for glioblastoma, an aggressive type of brain cancer with a high fatality rate. One reason that the disease is so difficult to treat is that most chemoth...
This is a coming-of-age story — involving your brain.
A new study by scientists at The Picower Institute for Learning and Memory at MIT provides the most comprehensive and rigorous evidence yet that the mammalian brain stores a single memory across a wid...
近日，暨南大学粤港澳中枢神经再生研究院周立兵和曲宜波团队在国际著名期刊Brain（IF=13.501）发表题为“Inactivating Celsr2 promotes motor axon fasciculation and regeneration in mouse and human”研究论文。本研究首次报道神经发育相关基因Celsr2调控脊髓运动神经元轴突再生，其作用在小鼠和人神经组织中具...
While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that ...

2022年2月，首都医科大学附属北京天坛医院神经外科张伟副教授团队在神经科学领域权威杂志《Brain》在线发表题为“An MRI radiomics approach to predict survival and tumour-infiltrating macrophages in gliomas”的研究论文。研究团队利用脑胶质瘤患者术前磁共振T2加权影像的纹理数据，通过机器学习算法构建了脑胶质...
Gut-brain connection in autism（图）
自闭症 肠脑连接 肠道炎症
2023/6/21
Many people with autism spectrum disorders also experience unusual gastrointestinal inflammation, but thus far scientists have not established whether and how those conditions might be linked.
The human brain uses more energy than any other organ in the body, requiring as much as 20% of the body’s total energy. While this may sound like a lot, the amount of energy would be even higher if th...
