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性个体差异之间的关联。

催眠是西方心理治疗的最古老形式,也是治疗多种疾病的有力循证疗法。催眠能力因人而异;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。在催眠性的功能性神经影像学研究中特别感兴趣的一个大脑区域是前扣带回皮层 (ACC)。在这里,我们检查了 ACC 中的神经化学物质 GABA 和谷氨酸与健康个体的催眠能力之间的关系。参与者接受了磁共振成像 (MRI) 会议,从而获得了 T1 加权解剖和 MEGA-PRESS 光谱扫描。通过对催眠功能神经影像学研究的定量荟萃分析指导在 ACC 上放置体素。使用催眠诱导概况 (HIP) 评估催眠能力,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 分数呈正相关,因此 GABA 浓度越高,个体越容易被催眠。对问卷分量表的探索性分析揭示了谷氨酸盐与 DES 的吸收和想象参与分量表之间的负相关。这些结果为催眠能力的个体差异提供了假定的神经生物学基础,并且可以告知我们对这种不断增长的心理治疗工具的治疗反应的理解。和负面影响完成。ACC GABA 浓度与 HIP 分数呈正相关,因此 GABA 浓度越高,个体越容易被催眠。对问卷分量表的探索性分析揭示了谷氨酸盐与 DES 的吸收和想象参与分量表之间的负相关。这些结果为催眠能力的个体差异提供了假定的神经生物学基础,并且可以告知我们对这种不断增长的心理治疗工具的治疗反应的理解。和负面影响完成。ACC GABA 浓度与 HIP 分数呈正相关,因此 GABA 浓度越高,个体越容易被催眠。对问卷分量表的探索性分析揭示了谷氨酸盐与 DES 的吸收和想象参与分量表之间的负相关。这些结果为催眠能力的个体差异提供了假定的神经生物学基础,并且可以告知我们对这种不断增长的心理治疗工具的治疗反应的理解。对问卷分量表的探索性分析揭示了谷氨酸盐与 DES 的吸收和想象参与分量表之间的负相关。这些结果为催眠能力的个体差异提供了假定的神经生物学基础,并且可以告知我们对这种不断增长的心理治疗工具的治疗反应的理解。对问卷分量表的探索性分析揭示了谷氨酸盐与 DES 的吸收和想象参与分量表之间的负相关。这些结果为催眠能力的个体差异提供了假定的神经生物学基础,并且可以告知我们对这种不断增长的心理治疗工具的治疗反应的理解。
