- 医疗成像医学成像
背景情况:
- 强迫性行为障碍 (CSBD) 在ICD-11中得到认可,但其神经支,特别是杏仁体的作用,仍然不清楚.
- 调查杏仁体在CSBD病原体中的功能对于理解这种疾病至关重要.
研究的目的:
- 通过一种新的分片化方法,探索杏仁体细分在CSBD神经元病变发生中的作用.
- 研究杏仁体功能连接,CSBD严重程度和心理因素之间的关系.
主要方法:
- 分析了45名患有CSBD的男性和26名健康对照者的休息状态功能磁共振成像 (fMRI) 数据.
- 使用复发量化分析 (RQA) 将杏仁体分为背中 (DM) 和腹侧 (VL) 的细分.

01:16Role of Amygdala in Memory
116
The amygdala is a small, almond-shaped structure responsible for processing and storing memories, particularly those linked to emotions like fear and stress. It plays an essential role in the brain's response to emotionally significant events and often enhances memory formation by triggering stress hormone release. The amygdala is vital for encoding and retrieving memories associated with fear or stress, a process that is adaptive by helping organisms avoid dangerous situations.

01:15Functional Brain Systems: Limbic System
2.1K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep...

28
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
