长期记忆是通过破坏并修复DNA实现的 在长期记忆形成时,一些大脑细胞会经历一阵强烈的电活动,以至于导致它们的DNA发生断裂。接着,炎症反应开始作用,修复这种损伤并帮助巩固记忆,一项对小鼠的研究表明了这一点。 Formation of memory assemblies through the DNA-sensing TLR9 pathway | Nature ...
拓扑绝缘体中的奇偶校验异常 诸平 The figure shows a schematic of the device used in the experiment. The re-entrant quantum Hall effect, where the electrical resistance goes back and forth when the magnetic field is increased, is a signature of the parity anomaly.(Image: Li-Xian Wang ...
