Individuals differ, of course, because biological processes are inherently variable. Even so, environmentally induced variation is such that understanding the mechanisms underlying plasticity has moved to centre stage of current research. The term 'plasticity' refers to the changeable character of matter....
In primates, about 90% of the cerebral cortex comprises the six-layered isocortex. The Ancient Greek term ‘isos’ means ‘equal’ or ‘same’. All areas of the isocortex have a similar appearance, although detailed analyses uncover regional differences that are used to subdivide the isocortex...

While pinning down a definition has proven tricky, "the general consensus is it's some means of information gathering," Katherine Twomey, a lecturer in language and communicative development at the University of Manchester in the United Kingdom...
Dunbar also worked with biologists to see if his hypothesis applies to other mammals besides primates. When they looked at meat eating mammals, carnivores, they found that the ones with a larger neocortex also have a bigger social group. And the number of individuals in that group is predicted...

severed (“commissurotomy”), in others only the corpus callosum was cut (“callosotomy”) and some patients fall somewhere in between these two boundaries. Now, the search term “split-brain” results in a total of 2848 publications in the database of the Web-of-Science and 29,300 ...
Jeremy Weinstein writes that “while external intervention offers the possibility of stopping mass killing in the short term, it may stunt processes of internal, institutional change that warfare reflects.” See Jeremy M. Weinstein, “Autonomous Recovery and International Intervention in Comparative Persp...
打个比方就好比每天晚上你的电脑或者手机要进入维护模式,进行磁盘碎片整理(memory 的转移和索引),安装固件更新漏洞补丁(增强免疫系统功能)之类的,喝醉昏睡过去大概就等价于强行拔掉电源——虽然两种情况电脑都黑屏了,但是第二天重启的时候立刻就会知道区别很大。而熬夜晚睡则相当于长期运行内存效率低下、没有补丁的“裸奔...
