概括
测试了对眼运动的高级眼群体平均化假设. 利多卡因对活跃神经元的禁用支持这样一个观点,即整个活跃细胞群体控制了冲击方向,振幅和速度.
科学领域:
- 神经科学是一个神经科学.
- 眼科医生 眼科 眼科
- 发动机控制器的控制器
背景情况:
- 较深层的上层结晶体对于启动和执行高速眼运动至关重要.
- 在每次saccade之前,上层结合体中的大量神经元会变得活跃.
- 从这个神经群体中提取冲击控制信号的精确机制仍然不清楚.
研究的目的:
- 为了研究眼运动参数 (方向,振幅,速度) 是如何被神经元群体编码在上层眼中.
- 为了测试人口平均化假设与替代的模型对抗saccade控制.
主要方法:
- 实验涉及使用利多卡因可逆性关闭上层结核中活跃神经元小子集的可逆性关闭.
- 分析的重点是眼睛运动特征的随之变化.
主要成果:
- 禁用一小部分活跃神经元产生了与人口平均假设一致的结果.
- 这些发现表明,曲轨迹是由整个群体的集体活动决定的,而不仅仅是最活跃的细胞.
结论:
- 斜眼运动的方向,振幅和速度是基于运动前活跃的整个细胞群体的综合反应.
- 这支持了在快速眼动过程中精确的运动控制的人口平均模型.

01:05Mechanism of Ciliary Motion
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...
