An electrical and systems engineer at Washington University in St. Louis has designed a method that, figuratively, forces a leopard to change its spots.Jr-Shin Li, the Das Family Distinguished Career ...
For decades, scientists have struggled to develop a comprehensive census of cell types in the brain. Now, in a pair of companion papers, researchers at Columbia’s Mortimer B. Zuckerman Mind Brain Beha...
德国科学家证明高低级脑区间用多个频段沟通信息
德国科学家 高低级脑区间 多个频段沟通信息
2016/2/26
人脑认知外部世界，视觉皮层要把外部信息从低级脑区传到高级脑区，但信息也会反向流动，那么大脑如何知道信息该怎么走呢？据每日科学网站近日报道，德国恩斯特·斯特格曼神经科学研究所与马普社会科学院合作，证明了人脑视觉皮层用什么频段取决于信息传输的方向。这一研究有助于理解某些精神疾病的成因，并在将来开发出相应疗法。
Caltech neuroscientists have looked inside brain cells as they undergo the intense bursts of neural activity known as "ripples" that are thought to underlie memory formation.During ripples, a small fr...

Scientists decode brain signals nearly speed of perception
2016/2/22
Using electrodes implanted in the temporal lobes of awake patients, scientists have decoded brain signals at nearly the speed of perception. Further, analysis of patients’ neural responses to tw...
Many animals, from insects to humans, are social. Their brains have evolved to be sensitive to sensory cues that carry social information, such as: speech sounds, pheromones and visual cues. But very ...

The brain uses similar computations to calculate the direction and speed of objects in motion whether they are perceived visually or through the sense of touch. The notion that the brain uses shared c...
神经元“过热”触发帕金森氏症
神经元 帕金森氏症
2015/8/28
加拿大蒙特利尔大学研究发现，帕金森氏症中脑细胞的死亡，或由神经元中的一种细胞能量危机形式引起，其需要非常高的能量来执行运动调节任务。
与阿尔茨海默氏症会影响数十亿脑神经元不同，帕金森氏症的主症状或由数万或数十万局部区域的脑神经元死亡造成，其中包括黑质、蓝斑和迷走神经背核。
引发帕金森氏症的关键在于线粒体，这个人体中的“发电站”使细胞生长，使神经元传送电信号并释放多巴胺、去甲肾上腺素和乙酰胆碱等...

Certain diseases, like Parkinson’s and Huntington’s disease, are associated with damage to the pathways between the brain’s basal ganglia regions. The basal ganglia sits at the base of the brain and i...
日本阿尔茨海默病病因研究取得进展
日本 阿尔茨海默病 病因
2015/8/11
据《日刊工业新闻》2015年5月12日报道，日本东京大学和美国斯坦福大学、华盛顿大学等组成的研究小组发现，阿尔茨海默病与脑神经活动的活跃程度有较大相关性。
截至目前的研究表明，β淀粉样蛋白在阿尔茨海默病发病过程中发挥着重要作用。研究小组利用光敏感通道(Channelrhodopsin)蛋白对患病实验鼠脑神经进行1日1回的光刺激，5个月后受刺激部分β淀粉样蛋白积蓄面积达到通常的2.5倍，分析得出脑...
