My wife (33 years old) has some 腿麻, 胳膊麻 etc lately. Her numbness is
sometimes on the left or right leg, arm, toes, fingers, and even face, but
never on all these places at the same time.
We went to our family doctor and he ordered a non-contrast brain MRI for her
. It turns out there is a sub-centimeter focus on her brain. Then our doctor
ordered a contrast MRI, the sub-centimeter focus is still there. Report 1)

How your brain makes moral judgments

This image shows differences in brain activity between people who judge an
act wrong and others who say it's not wrong.

involves emitting pollution toxic to the environment, but she doesn't care
because the goal is profit.

The following structures are, or have been considered to be, part of the

Hippocampus and associated structures: Hippocampus:[4][5][6] Required for
the formation of long-term memories and implicated in maintenance of
cognitive maps for navigation.(according to this article, this part was
obviously changed, so...)

直接联系。
研究人员扫描了工党议员Stephen Pound和保守党内阁国家发展大臣Alan Duncan的大
脑,向90名已被扫描过的学生询问了他们的政治观点。结果显示,保守派的成员有较大
的杏仁体和较小的前扣带(anterior cingulate)。杏仁体与焦虑和情绪相关,而前扣
带皮层则与勇气和乐观相关联。研究人员发现,这两个大脑区域的大小和受试者的政治
观点直接相关。 |

t******l 发帖数: 10908 | 8 我觉得对 non-musician 公鸭嗓,Semantic vs episodic 很难说。因为 mirror-
neuron 的存在,以及大脑可以 selectively inhibit motor function(比如一个证据
是做梦的时候不会梦游),很难说 non-musician 公鸭嗓听歌的时候是不是在默唱。如
果是默唱的话,那个就是 episodic memory 而不是 semantic memory,甚至还有可能
是 implicit memory。

My favorite physical activity is table tennis, which also happens to be the
world's best brain sport. It is highly aerobic and gets both the upper and
lower body moving in every which way — twisting, bending down low, reaching
up high, and shuffling from side to side. Plus, it gives your brain one
heckuva workout.
Also known as "ping-pong," the game is great for hand-eye coordination and
reflexes (cerebellum and parietal lobes). You have to focus (prefrontal
cortex) so you ... 阅读全帖 |
