概括

自主功能障碍和大脑连接性影响过度饮食 (BE). 特定的大脑路径,比如后带状皮质到下丘脑的后带状皮质,预测BE,而心率变化相互作用强调神经点进行干预.

科学领域:

神经科学是一个神经科学.
自主神经系统研究自主神经系统研究
饮食行为研究饮食行为研究

背景情况:

自主功能障碍与暴饮暴食 (BE) 行为有关.
之前的研究集中在BE的奖励,情绪和认知网络中的功能连接.
中央自治控制区的作用及其与北欧自治平衡的相互作用仍未得到充分研究.

研究的目的:

调查是否有效连接 (EC) 模式缓和了心率变化 (HRV) 和BE行为之间的关系.
为了确定特定的神经通路,涉及到脑自主相互作用的底层 BE.
探索BE行为潜在的生物标志物.

主要方法:

分析了来自158名健康成年人 (30名有BE) 的休息状态fMRI数据.
用光谱动态因果建模来评估在定义的饮食调节网络中的EC.
交叉验证 (LOOCV) 评估了EC模式的预测能力.

主要成果:

20个EC连接与BE相关 (后期概率>0.99).
从左后带带皮层到下丘脑的EC预测了群体成员身份 (AUC = 0.622).
大致预测了BE行为,由腹部体区域调节到下丘脑EC.

结论:

确定了与BE相关的大脑网络中的新型定向连接模式.
大脑自主相互作用,特别是涉及下丘脑和自主平衡标志物如HRV,都涉及到BE.
这些发现为未来的BE行为干预提供了潜在的目标.

Binge Eating Disorders

Binge Eating Disorders

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
