- 这些缺陷背后的精确神经机制,特别是与素缺乏有关的神经机制,尚未完全理解.
研究的目的:
- 通过使用高密度电脑图 (EEG) 来研究NT1中注意力和抑制缺陷的电生理基质.
- 探索这些神经机制与临床特征,特别是素水平之间的关联.
主要方法:
- 在Go/NoGo任务期间,从39名NT1患者和41名健康对照人中获得了高密度EEG记录.
- 分析了行为表现 (反应时间,错误) 和电生理数据 (P3延迟,NoGo-P3幅度,甲基频段功率,试验间相一致性).
主要成果:
- 与对照组相比,NT1患者的反应时间较慢,错误较多.

Narcolepsy
477
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

Sleep-Wake Cycles
2.7K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

Attention-Deficit/Hyperactivity Disorder
733
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

REM Sleep Behavior Disorder
1.3K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

Neural Regulation
43.1K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
