概括
阿尔法和mu大脑节奏显示非形波形形状,随着发育而变化. 这些大脑振荡在典型的发育儿童和ADHD或ASD儿童之间没有区别.
科学领域:
- 神经科学是一个神经科学.
- 发育神经科学的发展神经科学.
- 计算神经科学是一种神经科学.
背景情况:
- 阿尔法和mu节奏是人类大脑突出的振荡.
- 这些节奏对于关闭感官信息至关重要.
- 从EEG数据中分离混合的alpha和mu节奏是一个挑战.
研究的目的:
- 从大批儿童的EEG数据中分离和分析alpha和mu节奏.
- 描述这些节奏的波形形状的发育变化.
- 调查与ADHD和ASD相关的α频节律的潜在差异.
主要方法:
- 使用计算效率高的管道进行EEG数据处理,无需手动清洁.
- 从1605名儿童 (年龄在5-18岁) 中分离出α和/或mu节奏.
- 分析了循环循环的波形形状和振荡频率在发展过程中.
主要成果:
- 在整个发育过程中,在alpha和mu节奏中表现出显著的,非状波形形状变化.
- 随着年龄的增长,观察到振荡频率的显著变化.
- 与对照组相比,在ADHD或ASD组的静止状态α波段节律特征中没有发现显著差异.
结论:
- 阿尔法和mu节奏波形形状表现出显著的发育轨迹.
- 这些节奏的非形性质,经常被光谱分析所忽视,可能会告知生成模型.
- 静止状态α波段振荡测量没有在这个队列中区分ADHD或ASD.

Attention-Deficit/Hyperactivity Disorder
26
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....

Brain Waves
825
Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:
