Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

科学领域:

神经科学是一个神经科学.
认知心理学认知心理学
临床心理学临床心理学

背景情况:

多声元神经增强 (MNR) 降低了杏仁体对恐惧刺激的反应性,但其机制仍然不清楚.
这项试点研究调查了休息状态的功能性大脑连接性,作为MNR效应的潜在媒介.
了解这些机制对于优化恐惧症治疗至关重要.

研究的目的:

为了确定多声元神经强化对恐惧症的变化的潜在中间体.
为了检查休息状态的功能连接在治疗后的变化.
为了将连接性变化与杏仁体反应性降低相关联.

主要方法:

11名动物恐惧症患者接受了一次双盲多声素神经增强试验.
休息状态功能连接在治疗前和治疗后使用组ICA进行了评估.
连接性变化被分析用于预测杏仁体反应性减少.

主要成果:

一个共同的功能网络,重叠视觉网络,显示治疗后连接性增加.
