概括
在间歇性外向性 (IXT) 和适应性内向性 (AET) 的儿童中,光滑的追踪眼动有所不同. IXT的增益较低,而AET的跳动较多,这表明眼亚型的明显影响.
科学领域:
- 眼科医生 眼科 眼科
- 神经科学是一个神经科学.
- 儿科 儿科 儿科
背景情况:
- 顺的追踪 眼球运动对于视觉跟踪至关重要.
- 儿童常见的一种疾病 - - 斜视,会影响视觉发育.
- 有限的研究存在于特定的偏子类型的顺追求,如间歇性外向性 (IXT) 和适应性中向性 (AET).
研究的目的:
- 分析和比较IXT和AET儿童的光滑追踪眼动.
- 为了确定这些偏子类型和年龄相匹配的对照组之间的平滑追逐性能差异.
主要方法:
- 研究包括58名儿童 (4-13岁):AET (n=24),IXT (n=18) 和对照组 (n=16).
- 使用Tobii Pro X3眼睛追踪器 (120 Hz) 记录了眼睛的运动.
- 参与者执行平滑的追逐任务,水平移动的正弦形目标;增益,延迟和冲击频率被分析.
主要成果:
- 与对照组相比,IXT组的平滑追逐效果明显较低.
- 与对照组相比,AET组在追逐过程中表现出明显更多的预期性动.
- 两组之间没有发现追踪延迟的显著差异,尽管随着动而出现更快的反应.
结论:
- 偏会影响平稳的追逐,根据临床亚型产生不同的影响.
- 研究结果表明,在IXT中,平稳的追逐系统可能会受到更大的影响.
- 萨卡德系统可能在AET中受到更大的影响,与研究的假设保持一致.

Mass Analyzers: Common Types
1.6K
The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...

Titrimetric Methods: Types and Commonly Used Strategies
2.5K
In chemistry, titrimetric methods are broadly classified into three types: volumetric, gravimetric, and coulometric. Volumetric titrations involve measuring the volume of a titrant of known concentration that is required to react completely with an analyte. In gravimetric titrations, the standard solution reacts with the analyte to form an insoluble precipitate, which is filtered, dried, and weighed. In coulometric titrations, current is applied to an electrochemical reaction until the reaction...

Common Ion Effect
47.0K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

Smooth Endoplasmic Reticulum
8.2K
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Functions of Smooth Muscles
3.5K
Smooth muscles are an important type of muscle tissue that plays a vital role in the involuntary movements of internal organs. For example, they help regulate the movement of food through the gut and the flow of blood through the circulatory system.
Function of visceral smooth muscles
Visceral smooth muscle is found in the walls of all hollow organs, except the heart, and is a key player in the involuntary movements that drive the functioning of these internal organs. This tissue is arranged in...

Smooth Muscle Contraction
8.0K
Smooth muscle contraction is a complex process vital for various bodily functions, from maintaining blood vessel tension to facilitating the movement of food through the digestive tract. Unlike striated muscles, smooth muscle contraction begins more slowly and lasts longer.
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...
