职业,成了一名美发师。
这名来自南威尔士的男子现年26岁,名叫克里斯·伯奇。6年前,他在一次橄榄球

今天在娃的一本新版的娃版医学书上看到的,大意是说,
在 0 - 20 岁之间:
(注意是在 0 - 20 岁之间!!不是老态龙钟的岁月!!):
1. 娃的大脑灰质是随年龄增大越来越少。
2. 经常使用的大脑灰质会从原生态变成牛鼻态。
3. 不用的大脑灰质会被大脑自己干掉,尸骨无存,并且此过程不可逆。
4. 这不仅影响智力,还影响情感。
俺开始不相信,然后回家立马查了 NIH-> NIMH 的官方网页。。。

著:Mark Sincell 译:Shea
为了揭开隐藏在类星体背后的秘密,天体物理学家正在仔细研究它的微缩对应体——
微类星体,但是却发现微类星体带来了更大的谜团。
与普通的观点相反,黑洞是个挑剔的食客。尽管这些重达数十亿太阳质量的巨兽每年
可以吞食一个太阳质量的物质,但是它却为类星体提供动力而且会喷出等质量的物质。
数十年来,射电天文学天文学家发现有细长的喷流对从类星体的中心喷出,并且形成
巨大的“瓣”(lobe),有点像大象展开的耳朵。虽然已对此进行了深入的研究,但是,
“我们对喷流的认识仍是一无所知,”戈达德航天中心(Goddard Space Flight Center
)的天体物理学家琼·斯万克(Jean Swank)说。喷流由什么组成,它们形成的原因,是
什么使它们保持稳定——这些都是未解之谜。
问题是类星体的喷流变化得很缓慢。尽管有时喷流中个别的小云(blob)似乎会以超
光速运动——这是当物体本身具有极高的速度(接近光速)并且朝向地球运动时所产生的
光学错觉,但是喷流的确非常得长。一个单独的瓣就和星系中的旋臂等长。因 |

请各位医生赐教:
1. 穿刺是否必须?
2. 如果是恶性肿瘤,穿刺是否会造成肿瘤扩散、转移?是否会刺激肿瘤加速生长?
3. 是否可以要求手术切除,然后根据病理切片决定是否扩大清扫?
4. 如果是良性肿瘤,是否需要切除?
5. 可否观察一段时间再做决定?还是要尽快?
6. 有没有其他建议?

In 1959,Mullan and Penfield performed electrical stimulation and
intracranial
EEG recording during temporal lobe resection in epileptic patients, and
elicited a “dreamy state” akin to déjà vu. In 1978,Halgren obtained
similar results by stimulating the deeper structures of the hippocampus and
floor of the amygdala but could not reproducibly do so in the non-diseased
hemisphere

能通过学习大脑的缺损,比如说,一个人的头颅的prefrontal cortex部位受损,导致
他的语言和四肢协调功能丧失,那么我们就通过这个观察,就从中知道,我们人类的
prefrontal cortex掌管了我们的语言和协调的功能。
现在我知道了更多的大脑的理论,有一些真是非常非常的有趣,比如说,大脑胶质细胞
glia cells,负责把大脑神经元粘合在一起,相当于一种黏合剂,这种物质,在痛觉
传输中起到非常奇妙的作用;爱因斯坦的大脑解剖结果,显示了他的glia cell的数量
,比常人多。也许这是他比我们所有人都聪明的根本原因?
另一个有趣的例子是,联感,synesthesia, 一种不能算是疾病的感应,即,将颜色和
数字感应起来,具有这种感应的人,认为每个数字有一个相应的颜色,比如他认为,3
是温暖的黄色,9是高贵的紫色;通过对大脑的学习,科学家发现这类人的大脑,在掌
管数字和掌管颜色的部分,产生了某种反应。再比如,一个医生发现,他的家族中曾经
有过一位系列杀人狂,他将家族成员的脑部造影扫描收集起来,发... 阅读全帖 |
