Abstract

Background: Sensory processing sensitivity (SPS) is a biologically based temperament trait associated with enhanced awareness and responsivity to environmental and social stimuli. Individuals with high SPS are more affected by their environments, which may result in overarousal, cognitive depletion, and fatigue.

Method: We examined individual differences in resting-state (rs) brain connectivity (using functional MRI) as a function of SPS among a group of adults (M age = 66.13 ± 11.44 years) immediately after they completed a social affective "empathy" task. SPS was measured with the Highly Sensitive Person (HSP) Scale and correlated with rs brain connectivity.

Results: Results showed enhanced rs brain connectivity within the ventral attention, dorsal attention, and limbic networks as a function of greater SPS. Region of interest analyses showed increased rs brain connectivity between the hippocampus and the precuneus (implicated in episodic memory); while weaker connectivity was shown between the amygdala and the periaqueductal gray (important for anxiety), and the hippocampus and insula (implicated in habitual cognitive processing).

Conclusions: The present study showed that SPS is associated with rs brain connectivity implicated in attentional control, consolidation of memory, physiological homeostasis, and deliberative cognition. These results support theories proposing "depth of processing" as a central feature of SPS and highlight the neural processes underlying this cardinal feature of the trait.

感觉加工敏感性预测与加工深度相关的静息状态功能连通性的个体差异。

背景:感觉加工敏感性(SPS)是一种基于生物学的气质特征，与增强的意识和对环境和社会刺激的反应有关。SPS高的人更容易受到环境的影响，这可能会导致过度觉醒、认知消耗和疲劳。方法:研究了一组成年人(年龄为66.13±11.44岁)在完成社会情感“共情”任务后，静息状态(rs)脑连通性的个体差异(使用功能性MRI)。SPS用高敏感者(HSP)量表测量，并与大脑连通性相关。结果:结果显示腹侧注意、背侧注意和边缘网络之间的连通性增强是SPS增强的一个功能。兴趣区分析显示海马和楔前叶(涉及情景记忆)之间的大脑连通性增加;而杏仁核和导水管周围灰质(对焦虑很重要)以及海马体和脑岛(涉及习惯性认知处理)之间的连通性较弱。结论:本研究表明，SPS与大脑连通性有关，涉及注意控制、记忆巩固、生理稳态和审慎认知。这些结果支持了“加工深度”作为SPS核心特征的理论，并强调了该特征的基本特征背后的神经过程。

期刊介绍： The biological approach to mental disorders continues to yield innovative findings of clinical importance, particularly if methodologies are combined. This journal collects high quality empirical studies from various experimental and clinical approaches in the fields of Biological Psychiatry, Biological Psychology and Neuropsychology. It features original, clinical and basic research in the fields of neurophysiology and functional imaging, neuropharmacology and neurochemistry, neuroendocrinology and neuroimmunology, genetics and their relationships with normal psychology and psychopathology. In addition, the reader will find studies on animal models of mental disorders and therapeutic interventions, and pharmacoelectroencephalographic studies. Regular reviews report new methodologic approaches, and selected case reports provide hints for future research. ''Neuropsychobiology'' is a complete record of strategies and methodologies employed to study the biological basis of mental functions including their interactions with psychological and social factors.
