皮层

By comparing the tuning width of the input and output tuning curves, it is shown that the orientation selectivity is sharpened after being processed by the intracortical connection.

为了阐明这种锐化作用的机制，我们进一步分析了视皮层神经元的调制传递函数，观察到在输入和输出信号之间，存在着一种指数函数关系。

The result presented a direct morphological evidence for weakness of GABAergic intracortical inhibition ,which is considered to be a possible candidate for neural basis of age-related visual function decline, and further suggested that GABAergic neuron loss and decreased GABA synthesis might be responsible for above degradation.

本文结果为皮层内GABA能抑制系统减弱可能是介导老年性视觉功能衰退的机制提供了直接的形态学证据，且进一步提示：GABA能神经元的丢失和递质合成的减少可能是介导以上所述的功能衰退的重要因素。

By comparing the tuning width of the input and output tuning curves, it is shown that the orientation selectivity is sharpened after being processed by the intracortical connection.

将同一神经元的输入和输出曲线进行比较可以看出，经过视皮层内神经回路加工以后，方位调谐曲线的宽度变窄，调谐特性被明显地锐化。

Moreover, the S1 area was shown to be more easily activated and more intensively innervated by the thalamocortical afferent projections than by the intracortical connections.

其次，刺激IV层在每一刺激强度下诱发的场电位幅度远远大于刺激II-III的场电位幅度，即S1区更容易被丘脑皮层连接回路的投射纤维所激活。

They include a pronounced knoblike structure in the part of the motor cortex that controls the left hand; in other studies, similar "knobs" have been associated with musical ability.

福尔克称，她在爱因斯坦的大脑中发现了一些以前没有认识到的异常特征，其中包括：在控制左手的运动皮层上发现了显著的球状结构；其他的研究发现，类似的球状结构跟爱因斯坦的音乐能力相关。

Histological analysis showed that the cerebral cortex of Syne DKO and SUN DKO mice displayed severe laminary defects.

组织学分析发现，两种双敲除小鼠的皮层发育严重受损，无法正常分层。

NOS neurons atrophy markedly in laterodorsal tegmental nucleus of aged mice. NOS neurons and synapses atrophy in Alzheimer's disease patient temporal cortex and amygdala, NOS neurons decrease by 18-33% in hippocampus.

衰老时NOS神经元发生了某些变化，老龄小鼠被盖背外侧核NOS神经元明显萎缩；Alzheimer's病人颞叶皮层和杏仁核NOS细胞及突触显著绉缩，海马分子层内侧1/3缺少NOS神经元，NOS神经元减少18～30%。

In the original studies,[4,5] all the acute stroke patients with angiographically proven internal carotid artery or M1 occlusion had ALN, presumably because the lentiform nucleus is fed by lenticulostriate arteries from M1 without collateral flow from cortical anastomoses.

先前的研究报道：所有经脑血管造影证实存在颈内动脉闭塞或大脑中动脉M1段闭塞的急性卒中患者，都会出现豆状核低信号征；可能系豆状核是由大脑中动脉M1段发出的豆纹动脉供血，缺乏来源于皮层吻合支的侧枝循环供血所致。

Through analysis the average CR of cortex and that of caudate nucleus and lentiform have correlation with MMSE scores of HD.

与磁共振成像比较，分析病人的PET影像特点；测量了病人的平均皮层、豆状核和丘脑的间接放射性计数，与病人的神经心理测量得分、统一的HD运动评分和生活自理能力评分进行比较分析。

In addition, the loss of the gray-white differentiation in the cortical ribbon (particularly at the lateral margins of the insula) or the lentiform nucleus and sulcal effacement can often be detected within 6 hours in up to 82% of patients with large-vessel anterior circulation occlusions.

另外，82％的前循环大动脉闭塞的患者，于发病6小时内，CT即可发现岛带征（岛叶外侧缘皮层灰白质分界消失）、豆状核低信号征、半球脑沟消失征；这些早期CT征象的出现往往提示预后不良。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
