摘要

自闭症谱系障碍(ASD)的典型特征是社会交往和沟通障碍,这可能与无法自然地适应社会刺激有关,尤其是在识别和应对面部情绪方面。由于以往的研究大多使用非社交刺激来研究 ASD 儿童和成人的抑制控制能力,因此人们对 ASD 青少年情绪抑制控制的行为和神经激活模式知之甚少。功能神经影像学研究强调了前额叶皮层(PFC)在抑制控制和情绪面孔处理中的关键作用。因此,本研究旨在通过非侵入性功能性近红外光谱(fNIRS)检查患有自闭症的青少年在完成情绪侧翼任务时是否表现出前额叶皮层处理的改变。研究人员招募了21名患有高功能自闭症的青少年和26名发育典型(TD)青少年,年龄在13-16岁之间。所有参与者都接受了情绪侧翼任务,该任务要求他们判断中心位置的面部情绪是否与侧面位置的面部情绪一致。TD青少年在不一致条件下的RT和平均O2Hb水平均高于一致条件下,主要是右侧PFC区域的皮质激活对情绪Flanker效应做出了反应。与此相反,ASD 青少年在处理一致与不一致的情绪面孔时,在反应时间上没有表现出优势,但在对情绪侧翼效应做出反应时,主要在左侧前脑皮层区域表现出皮层激活。这些研究结果表明,患有ASD的青少年在抑制情绪面孔时,会依靠不同的神经策略来调动PFC神经资源,以解决他们遇到的困难。

Atypical prefrontal neural activity during an emotional interference control task in adolescents with autism spectrum disorder: A functional near-infrared spectroscopy study
Autism spectrum disorder (ASD) is typically characterized by impairments in social interaction and communication, which may be associated with a failure to naturally orient to social stimuli, particularly in recognizing and responding to facial emotions. As most previous studies have used nonsocial stimuli to investigate inhibitory control in children and adults with ASD, little is known about the behavioral and neural activation patterns of emotional inhibitory control in adolescent with ASD. Functional neuroimaging studies have underscored the key role of the prefrontal cortex (PFC) in inhibitory control and emotional face processing. Thus, this study aimed to examine whether adolescent with ASD exhibited altered PFC processing during an emotional Flanker task by using non-invasive functional near-infrared spectroscopy (fNIRS). Twenty-one adolescents with high-functioning ASD and 26 typically developing (TD) adolescents aged 13–16 years were recruited. All participants underwent an emotional Flanker task, which required to decide whether the centrally positioned facial emotion is consistent with the laterally positioned facial emotion. TD adolescents exhibited larger RT and mean O2Hb level in the incongruent condition than the congruent condition, evoking cortical activations primarily in right PFC regions in response to the emotional Flanker effect. In contrast, ASD adolescents failed to exhibit the processing advantage for congruent versus incongruent emotional face in terms of RT, but showed cortical activations primarily in left PFC regions in response to the emotional Flanker effect. These findings suggest that adolescents with ASD rely on different neural strategies to mobilize PFC neural resources to address the difficulties they experience when inhibiting the emotional face.

期刊介绍: NeuroImage, a Journal of Brain Function provides a vehicle for communicating important advances in acquiring, analyzing, and modelling neuroimaging data and in applying these techniques to the study of structure-function and brain-behavior relationships. Though the emphasis is on the macroscopic level of human brain organization, meso-and microscopic neuroimaging across all species will be considered if informative for understanding the aforementioned relationships.
