处理关于社会疼痛的词汇会激活类似于身体疼痛的大脑区域,这表明共享的神经通路. 然而,与社交疼痛词相比,身体疼痛词涉及的脑部区域较少.
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
背景情况:
- 处理语义疼痛,就像与身体疼痛相关的单词一样,影响疼痛感知.
- 社会痛苦,源于排斥或损失,也可能类似地调节疼痛感知.
- 了解 nociceptive 和语义疼痛之间共享的神经基质至关重要.
研究的目的:
- 为了比较大脑在痛感疼痛期间的活动与处理身体和社会疼痛词.
- 识别不同类型的疼痛语义的共同和独特的神经基质.
- 为了研究感官疼痛和情感驱动的疼痛概念之间的神经重叠.
主要方法:
- 与事件相关的功能磁共振成像 (fMRI) 用于34名健康女性.
- 参与者接受了可感知刺激和语义文字处理 (积极,消极,身体疼痛,社会疼痛) 的会议.
- 刺激的不愉快性和词的特征 (价值,兴奋,疼痛相关性) 被评分.
主要成果:
- 感知疼痛激活了SI,SII,insula, cingulate皮质,thalamus,以及背侧前额皮质.
- 与负面词相比,社交疼痛词增加了类似大脑区域的活动.
- 身体疼痛的词语只激活左上边缘环,部分激活后中心环.
结论:
- 语义性疼痛部分与感知性疼痛共享神经基质.
- 社会疼痛词涉及到一个广泛的网络,与 nociception 的情感-动机方面重叠.
- 身体疼痛词重叠与感官歧视性 nociception 的方面,但在有限的区域.
