Abstract

Objective

Infant hypersensitivity affects daily challenges and parental stress. Although the crucial role of tactile sensation in infants' brain function has been highlighted, hypersensitive infants and their families lack support. Electroencephalography may be useful for understanding hypersensitivity traits. We investigated the relationship between infant perceptual hypersensitivity and parental stress, somatosensory-evoked potential (SEP), and magnitude-squared coherence (MSC) in the general population.

Methods

Infants aged 8 months (n = 63) were evaluated for hypersensitivity and parental stress using a questionnaire and for cortical activity using electroencephalography. Vibration stimuli were applied to the infant’s left foot. SEP components that peaked around 150 ms (N2) and at 200 ms (P2) after stimulus onset were evaluated by amplitude and latency at the midline electrode (Cz) and MSC between the midline electrodes (C3–C4).

Results

Parental stress was associated with infant hypersensitivity. The latency of Cz was delayed, and C3–C4 delta MSC was high in infants with hypersensitivity.

Conclusions

Increasing inter-hemispheric MSC synchrony in the stimulated condition in infants with hypersensitivity suggested atypical somatosensory cortical function.

Significance

These findings contribute to identifying, understanding the mechanisms of, and developing effective coping strategies for early-stage hypersensitivity.

8个月大超敏反应的大脑半球间体感连贯性和父母压力：脑电图研究

目标婴儿的超敏反应会影响日常挑战和父母的压力。尽管触觉在婴儿大脑功能中的重要作用已得到强调，但对触觉过敏的婴儿及其家庭仍缺乏支持。脑电图可能有助于了解超敏性特征。我们调查了普通人群中婴儿知觉超敏与父母压力、体感诱发电位（SEP）和幅度-平方一致性（MSC）之间的关系。方法使用调查问卷评估 8 个月大婴儿（n = 63）的超敏和父母压力，并使用脑电图评估大脑皮层活动。在婴儿的左脚上施加振动刺激。根据中线电极（Cz）和中线电极（C3-C4）之间的 MSC 的振幅和潜伏期评估了刺激开始后 150 毫秒（N2）和 200 毫秒（P2）左右达到峰值的 SEP 成分。结论超敏反应婴儿在受刺激状态下半球间间质同步性增加，表明体感皮层功能不正常。

期刊介绍： As of January 1999, The journal Electroencephalography and Clinical Neurophysiology, and its two sections Electromyography and Motor Control and Evoked Potentials have amalgamated to become this journal - Clinical Neurophysiology. Clinical Neurophysiology is the official journal of the International Federation of Clinical Neurophysiology, the Brazilian Society of Clinical Neurophysiology, the Czech Society of Clinical Neurophysiology, the Italian Clinical Neurophysiology Society and the International Society of Intraoperative Neurophysiology.The journal is dedicated to fostering research and disseminating information on all aspects of both normal and abnormal functioning of the nervous system. The key aim of the publication is to disseminate scholarly reports on the pathophysiology underlying diseases of the central and peripheral nervous system of human patients. Clinical trials that use neurophysiological measures to document change are encouraged, as are manuscripts reporting data on integrated neuroimaging of central nervous function including, but not limited to, functional MRI, MEG, EEG, PET and other neuroimaging modalities.
