- 运动生理学 运动生理学
- 认知心理学 认知心理学
背景情况:
- 过渡性低面性假说表明,在强烈的身体压力下,认知功能下降.
- 之前对前额叶皮层 (PFC) 氧化和运动期间执行功能 (EF) 的研究产生了相互矛盾的结果.
- 功能近红外光谱 (fNIRS) 通常用于测量PFC在此类任务中的氧化.
研究的目的:
- 系统地审查fNIRS研究,调查PFC氧化在高强度运动期间EF变化中的作用.
- 为了确定PFC氧化是否能机械地解释在体力压力下认知性能下降.
- 综合来自双重任务范式的发现,同时评估EF与练习.
主要方法:
- 在五个数据库中按照PRISMA指南进行系统的文献搜索.
- 包括使用fNIRS测量高强度运动期间PFC氧化量的研究,使用双任务范式.

01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
