概括

高频重复性横磁性刺激 (rTMS) 在轻度认知障碍 (MCI) 患者中改善了视觉工作记忆 (VWM). 这种增强与改变的大脑波相互作用有关,特别是α-gamma交叉频率合 (CFC).

科学领域:

神经科学是一个神经科学.
认知科学认知科学
神经调节是一种神经调节.

背景情况:

交叉频率合 (CFC),特别是α-gamma相互作用,对于认知功能至关重要.
重复性跨磁刺激 (rTMS) 显示了调节神经振荡和认知表现的潜力.

研究的目的:

研究高频rTMS (HFrTMS) 对轻度认知障碍 (MCI) 患者的CFC和视觉工作记忆 (VWM) 的影响.

主要方法:

20名MCI患者和20名健康对照人接受了10Hz的rTMS,目标是左侧脊侧前额皮层 (DLPFC).
在干预前和后评估了VWM性能和神经振荡 (α和gamma波段).

主要成果:

患有MCI的患者在HF rTMS后显示出显著的VWM改善,特别是在低记忆负载下.
这些认知收益与尾玛活性降低相关.
在rTMS后观察到,前额α和后额的马振荡之间加强了阶段振幅合 (PAC).

结论:

阿尔法频段HF rTMS可以有效调节MCI患者的神经活动,包括CFC.
这种非侵入性神经调节技术为增强MCI认知功能提供了有前途的治疗策略.

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.
