概括

在背侧前额皮层 (DLPFC) 上持续的甲突发刺激 (cTBS) 影响情绪注意力. 真正的cTBS与情感图像相比,减缓了对中性图像的注意力,突出了DLPFC.

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
神经调节是一种神经调节.

背景情况:

甲爆刺激 (TBS) 是一种时间效率高的跨脑磁性刺激协议.
它对情感注意力的影响需要进一步研究.
脊侧前额皮层 (DLPFC) 是认知调制的一个关键区域.

研究的目的:

调查连续TBS (cTBS) 对左侧和右侧DLPFC的差异性影响.
检查cTBS如何调节对情绪 (愉快,痛苦) 和中性刺激的注意力.
评估cTBS对情绪注意力的半球特异性影响.

主要方法:

随机对照试验与91名健康的年轻成年人.
真实或假的cTBS应用于左或右DLPFC.
计算机化点探测任务评估对情感和中性图像的注意偏差.

主要成果:

与情感图像相比,真正的cTBS导致探测器对中性图像的反应更慢,取代了情感图像.
在假设条件下,在刺激类型之间没有观察到显著的差异.
对于情绪刺激,没有发现半球依赖的效应,这表明左和右DLPFC刺激的可比调制.

结论:

通过cTBS进行DLPFC刺激,可以调节注意力控制,特别是对于情绪刺激.
这些发现支持DLPFC在注意力偏差中的作用.
结果为优化cTBS协议以提高认知能力提供了洞察力.

关键词:

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...
