The results showed that during perception of disgust facial expressions , brain activation exists mainly in the insula , frontal operculum , fusiform gyrus , parietal gyrus , orbitofrontal cortex , temporal cortex , and occipital gyrus .

结果发现厌恶面孔图片主要激活了脑岛、额叶岛盖、梭状回、顶叶、眶额叶下部、颞叶和枕叶这些区域。

Results The activation areas were found in bilateral or unilateral motor cortex , somatosensory cortex , prefrontal cortex , temporal cortex , premotor cortex , insula , frontal operculum , basal ganglia ( putamen ), parietal cortex and cingulate .

结果实验组10名受试者在单侧或双侧的运动皮层、感觉皮层、前额叶皮层、颞叶皮层、前运动皮层、脑岛、额盖、基底神经节壳核、顶叶皮层及扣带回等区域有明显激活。

Methods In indoor immersing experimentation , the experiments were divided into 4 groups , 30 snails in each group , to observe the rate of opening operculum , the rate of climbing adhersion and the rate of death at 3 , 6 and 24 hours respectively .

方法室内浸泡试验，试验分为4组，每组30只钉螺。分别于3、6、24h观察钉螺开厣率和上爬附壁率和死亡率。

There were notable differences in six targets ( egg width , egg lid height , the thickness of side wall and end wall , thorn length and width )( P < 0.01 ) . The contact between the operculum and the shell appears to be uneven but not indented .
