Abstract

Background

The Rolandic ∼20-Hz beta rhythm of the sensorimotor cortex is associated with motor function and perception. However, the modulation of this rhythm by different emotional stimuli is an innovative area of research.

Aims

This study aims at investigating the impact of affective pictures (positive, negative, and neutral) on the proprioceptive modulation of the Rolandic ∼20 Hz beta rhythm in typically developing children and children with neurodevelopmental disorders (i.e. cerebral palsy and autism).

Methods and procedures

EEG was recorded while participants experienced passive wrist movements during the simultaneous viewing of affective pictures. Time-frequency analysis of the sensorimotor oscillatory activity was performed.

Outcomes and results

Our findings revealed that pictures with negative emotional valence notably diminish event-related synchronization (ERS) amplitude during the perception of hand movement in all groups of children.

Conclusions and implications

These findings suggest that emotional stimuli, particularly the negative ones, could significantly influence brain's processing of proprioception, adding knowledge to the interaction of common comorbidities, such as sensorimotor disorders and emotional dysregulation, in children with neurodevelopmental disabilities.

消极情绪会降低发育正常儿童和神经发育不良儿童在本体感觉调节萝兰∼20HZβ节律过程中的感觉运动皮层活动

背景感觉运动皮层的罗兰蒂克∼20赫兹β节律与运动功能和知觉有关。本研究旨在调查情感图片（积极、消极和中性）对典型发育儿童和神经发育障碍儿童（即脑瘫和自闭症儿童）Rolandic ∼20 Hz β节律本体感觉调制的影响。结论和启示这些研究结果表明，情绪刺激，尤其是负面情绪刺激，会显著影响大脑对本体感觉的处理，从而为神经发育障碍儿童常见合并症（如感觉运动障碍和情绪失调）之间的相互作用增添了新的知识。

期刊介绍： Research In Developmental Disabilities is aimed at publishing original research of an interdisciplinary nature that has a direct bearing on the remediation of problems associated with developmental disabilities. Manuscripts will be solicited throughout the world. Articles will be primarily empirical studies, although an occasional position paper or review will be accepted. The aim of the journal will be to publish articles on all aspects of research with the developmentally disabled, with any methodologically sound approach being acceptable.
