前扣带皮层(ACC)被认为参与了情绪、疼痛和认知控制等功能。虽然在人类和非人类哺乳动物中的研究促进了我们对ACC功能的理解,但ACC活性的主观相关性在很大程度上仍未被探索。在目前的研究中,我们表明,在前中扣带皮层(aMCC)的电荷传递激发自主神经的变化和一个迫在眉睫的挑战加上一个坚定的态度,以克服它的预期。静息态连接分析显示,两名患者的刺激部位都位于一个大的-连接aMCC与额岛、额极以及一些皮层下区域的规模分布网络。这份报告提供了令人信服的,第一人称帐户的电刺激这个大脑网络,并建议其可能参与精神病理条件的特点是降低能力,以承受心理或身体痛苦。
Anterior cingulate cortex (ACC) is known to be involved in functions such as emotion, pain, and cognitive control. While studies in humans and non-human mammals have advanced our understanding of ACC function, the subjective correlates of ACC activity have remained largely unexplored. In the current study, we show that electrical charge delivery in the anterior mid-cingulate cortex (aMCC) elicits autonomic changes and the expectation of an imminent challenge coupled with a determined attitude to overcome it. Seed-based, resting-state connectivity analysis revealed that the site of stimulation in both patients was at the core of a large-scale distributed network linking aMCC to the frontoinsular and frontopolar as well as some subcortical regions. This report provides compelling, first-person accounts of electrical stimulation of this brain network and suggests its possible involvement in psychopathological conditions that are characterized by a reduced capacity to endure psychological or physical distress.
