signal changes were observed within contralateral primary motor cortex in subjects of control group. the maximal signal pixel time-signal curve was the same to the movement of block model.
aim:to study the expression changes of heat shock protein 27(hsp27) in the pyramidal tract neurons(ptns) of the rat primary motor cortex following the pyramidal tract injury.
目的:探讨大鼠锥体束损伤后不同时间点脑内锥体束神经元热休克蛋白27表达的变化。
the result showed that the signal changes were seen in the left primary motor cortex when epi was used.
结果表明功能图像上可见左侧初级运动皮层区的信号变化,而在本实验中梯度回波图像上结果为阴性。
all the patients in the treatment group when performing upper limb movementactivating area could be found at contralateral primary motor cortex where was similar as normal persons with similar form.
治疗组所有患者健侧上肢运动时,均可在对侧初级运动皮质观察到激活区,出现部位和形态与正常人大致相仿。
there was significant difference of average adc value between primary motor cortex and lateral orbital cortex, caudate putamen (p0.05).
运动皮质与视觉皮质、尾状核之间的adc值差别有统计意义(p均0.05)。
results: statically significant mr signal changes were observed within contralateral primary motor cortex in all subjects and movement conditions.
