概括
甲状腺皮质节律失常 (TCD) 和奖励缺陷综合征 (RDS) 分享大脑区域,如背前环状皮质 (dACC). 然而,它们在先前带状皮层 (pgACC) 活动上有所不同,这表明它们具有不同的不确定性处理机制.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 计算神经科学是一种神经科学.
背景情况:
- 精神疾病共享一个解剖核心 (背前环状皮层 (dACC) 和前半岛) 来处理不确定性.
- 甲状腺皮质节律失常 (TCD) 涉及交叉频率合,而奖励缺陷综合征 (RDS) 则与下多巴胺类病理有关.
- 一些RDS表现出TCD的神经生理特征,这表明存在潜在的联系.
研究的目的:
- 研究TCD和RDS的共同解剖和神经生理核心.
- 为了确定区分TCD和RDS之间的神经生理机制.
- 探索前前带带皮层 (pgACC) /腹中前额皮层 (vmPFC) 和dACC平衡在这些条件下的作用.
主要方法:
- 在源空间中分析683个受试者的脑电图 (EEG).
- 比较TCD和RDS与健康对照组,以及TCD和RDS组之间的比较.
- 在pgACC/vmPFC和dACC之间计算电流密度平衡.
主要成果:
- TCD和RDS具有共同的解剖学和神经生理核心:dACC中的β活性和dACC中的β活性延伸到前皮质和后侧前额皮质.
- 在pgACC/vmPFC活性方面,TCD和RDS有所不同.
- 在TCD和RDS之间观察到pgACC/vmPFC和dACC之间的相反平衡.
结论:
- TCD和RDS在特定的大脑区域具有共同的神经生理基础.
- 在pgACC/vmPFC和dACC平衡的差异区分TCD和RDS.
- 这两种情况都可以被概念化为不确定性障碍,在关键大脑区域具有相反的调节机制,可能由反转的U形状解释.

Anxiety: Overview
248
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Disturbances in Heart Rhythm
909
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...

Disorders of the Autonomic Nervous System
573
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Mechanism of Cardiac Arrhythmias
892
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Panic Disorder
38
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...
