主要是記述在我學我的身體時得到的一些拉七拉雜的資料,不過我想可能不是對我自己有用而已,所以有一些我會多多少少地改成中文化。all the news may be the important informations so i would translate to short notes here. [2010.05.29]

Natural self-repair mechanisms that kick in after spinal cord injury identified

ScienceDaily (2010-05-31) -- University of Alberta researchers have identified one of the body's natural self-repair mechanisms that kick in after spinal cord(脊髓) injury which could lead to the development of more effective treatments.

To help understand the discovery the researchers say it is important to first describe the neurons in the spinal cord that control muscle contractions. These neurons represent a fairly autonomous part of the nervous system that control many basic functions such as walking and bladder control. These neurons are brought into a state of readiness by a transmitter called serotonin. Serotonin originates in the brain and projects down the spinal cord where it binds to serotonin receptors on the neurons. This process turns a quiet neuron into one that's ready to respond to fast inputs from the brain.
