Except muscular motor activity,the different distribution pattern of CGRP-LI content in SOL-Mn and EDL-Mn pools is related to different 5-HT inputs. SOL-Mns may receive more 5-HT inputs.

• 调质CGRP在 SOL - Mn群和 EDL - Mn群的配布式样差异除与其所支配肌肉的功能活动方式密切相关外 ,还受到脊髓 5 -HT传入信息的影响 ,SOL - Mn群可能比 EDL - Mn群接受更多的 5 - HT能信息。
