概括
具有FMR1前变异 (PC) 的男性的执行功能下降之前和预测脆弱的X相关/无氧综合征 (FXTAS). 认知能力的这些变化是发展运动障碍的早期预警信号.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
- 神经学 神经学
背景情况:
- 在男性中,脆弱的X关联震/缺氧综合征 (FXTAS) 与执行功能障碍有关,包括抑制和注意力缺陷.
- 以前的研究表明早期的执行功能变化,但缺乏纵向数据来证实这一假设.
研究的目的:
- 调查FMR1前变异载体 (PC) 中的执行功能恶化是否先于并预测了FXTAS的发展.
- 建立对PC认知变化的纵向理解.
主要方法:
- 一项纵向研究追踪了66个FMR1PC和31个健康对照 (HC) 在1-9年内.
- 参与者在多次访问中完成了执行功能-成人版本 (BRIEF-A) 的行为评级清单;28个PC开发了FXTAS.
主要成果:
- 与对照组相比,前变异载体在元认知指数 (MI) 中与年龄相关的下降更大.
- FXTAS的发展与MI和行为调节指数 (BRI) 评分的恶化相关.
- 基线自我报告的执行功能问题预测了以后的FXTAS发作.
结论:
- 男性PC的执行功能变化作为FXTAS的前症候群.
- 早期的认知改变是未来运动障碍发展的关键指标.

Role of Cerebellum and Prefrontal Cortex in Memory
443
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

Amyloid Fibrils
9.6K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...
