Hypnosis is the oldest form of Western psychotherapy and a powerful evidence-based treatment for numerous disorders. Hypnotizability is variable between individuals; however, it is a stable trait throughout adulthood, suggesting that neurophysiological factors may underlie hypnotic responsiveness. One brain region of particular interest in functional neuroimaging studies of hypnotizability is the anterior cingulate cortex (ACC). Here, we examined the relationships between the neurochemicals, GABA, and glutamate, in the ACC and hypnotizability in healthy individuals. Participants underwent a magnetic resonance imaging (MRI) session, whereby T1-weighted anatomical and MEGA-PRESS spectroscopy scans were acquired. Voxel placement over the ACC was guided by a quantitative meta-analysis of functional neuroimaging studies of hypnosis. Hypnotizability was assessed using the Hypnotic Induction Profile (HIP), and self-report questionnaires to assess absorption (TAS), dissociation (DES), and negative affect were completed. ACC GABA concentration was positively associated with HIP scores such that the higher the GABA concentration, the more hypnotizable an individual. An exploratory analysis of questionnaire subscales revealed a negative relationship between glutamate and the absorption and imaginative involvement subscale of the DES. These results provide a putative neurobiological basis for individual differences in hypnotizability and can inform our understanding of treatment response to this growing psychotherapeutic tool.

前扣带回神经化学浓度与催眠能力个体差异之间的关联

催眠是西方心理治疗的最古老形式,也是许多疾病的有力证据支持。催眠力在个体之间是可变的。然而,它是整个成年期的稳定特征,表明神经生理因素可能是催眠反应的基础。在功能神经影像学的催眠性研究中,特别感兴趣的一个大脑区域是前扣带回皮质(ACC)。在这里,我们检查了健康个体的ACC中神经化学物质,GABA和谷氨酸之间的关系以及催眠作用。参与者进行了磁共振成像(MRI),从而获得了T1加权解剖和MEGA-PRESS光谱扫描。通过对催眠的功能性神经影像学研究进行定量荟萃分析,指导在ACC上体素的放置。使用催眠诱导概况(HIP)评估催眠作用,并完成自我报告问卷以评估吸收(TAS),解离(DES)和负面影响。ACC GABA浓度与HIP得分呈正相关,因此GABA浓度越高,个体的催眠作用就越大。问卷调查量表的探索性分析显示,谷氨酸与DES的吸收量和想象力参与量表之间呈负相关。这些结果为催眠能力的个体差异提供了推定的神经生物学基础,并且可以为我们对这种不断增长的心理治疗工具的治疗反应提供了解。和负面影响已经完成。ACC GABA浓度与HIP得分呈正相关,因此GABA浓度越高,个体的催眠作用就越大。问卷调查量表的探索性分析显示,谷氨酸与DES的吸收量和想象力参与量表之间呈负相关。这些结果为催眠能力的个体差异提供了推定的神经生物学基础,并且可以为我们对该增长的心理治疗工具的治疗反应提供了解。和负面影响已经完成。ACC GABA浓度与HIP得分呈正相关,因此GABA浓度越高,个体的催眠作用就越大。对问卷子量表的探索性分析显示,谷氨酸与DES的吸收量和想象力参与量表之间呈负相关。这些结果为催眠能力的个体差异提供了推定的神经生物学基础,并且可以为我们对这种不断增长的心理治疗工具的治疗反应提供了解。对问卷子量表的探索性分析显示,谷氨酸与DES的吸收量和想象力参与量表之间呈负相关。这些结果为催眠能力的个体差异提供了推定的神经生物学基础,并且可以为我们对这种不断增长的心理治疗工具的治疗反应提供了解。对问卷子量表的探索性分析显示,谷氨酸与DES的吸收量和想象力参与量表之间呈负相关。这些结果为催眠能力的个体差异提供了推定的神经生物学基础,并且可以为我们对这种不断增长的心理治疗工具的治疗反应提供了解。
