神经问题

ob

一个人在正常体重时和超重时的皮肤对外界刺激，例如针刺的敏感程度是一样的吗？如果不是，那种情况更敏感？

另一个问题：人的体重增加时神经也应跟着生长。那么，人在减肥时，神经的状态如何呢？

可以抓个演员做实验。某些演员为了适合角色要求，频繁增肥减肥。设计一个神经传导反应实验，请一个过来，装上传感器和记录仪。。。 www.ddhw.com   www.ddhw.org--- 据说这世界是彩色的？

take mathematician's approach to simplfy the complicated system. Assume the two types of people, slim and fat, as two skin covered meat balls with identical internal structure, but with different radii, and hence different surface areas. www.ddhw.com Because of ...., and.... hence...... therefore the slim one is more sensitive.

www.ddhw.com First of all, you have to take into account some physiological factors, including whether or not nervous tissue could grow into the layer of hypodermal fat... and the distribution of the nerves in different tissue types, fat and muscle... Second, you have to make sure the speed at which the signals excited by the stimuli transmit from the surface to the nerve centre and the brain stays unchanged across the fat and the muscles... Then count in the radii and surface areas factors... Just assume that your presumption of homogeneous skin-covered meat balls holds... Your conclusion might be wrong, as I reckon nerves could grow very well in the hypodermal fat, otherwise fat people would miserably lose their sense of touch.... and God knows the signals could not travel faster in fat tissues?   www.ddhw.com Well.... It might be easier to make an investigation, get the statistical data, put them into the SPSS, and fix a regression model, get the coefficients, then you will know....      www.ddhw.com     本贴由[色盲]最后编辑于：2007-10-14 12:18:40   www.ddhw.org--- 据说这世界是彩色的？
