Abstract

Objective: This study aims to investigate the brain activity patterns of both deaf and hearing children during the processing of three different tones (first tone, second tone, and third tone) utilizing resting-state functional magnetic resonance imaging (fMRI). Furthermore, the study seeks to identify disparities in brain activation regions between deaf and hearing children while engaged in the tone processing task. Methods: The study enlisted a cohort of five deaf children and two hearing children as participants. Resting-state functional magnetic resonance imaging (fMRI) scans were conducted on these subjects utilizing an fMRI scanner. The acquired fMRI data underwent preprocessing and subsequent analysis to scrutinize the patterns of brain activity. Results: During tone recognition tasks, it becomes evident that deaf children and hearing children exhibit variations in brain activation regions. These discrepancies manifest across multiple areas, including the pre-central gyrus, superior temporal gyrus, middle occipital gyrus, supplementary motor area, superior parietal lobe, and interior frontal gyrus, among others. A comparative analysis suggests the possibility that the brains of deaf children demonstrate heightened plasticity and compensatory mechanisms. These findings significantly contribute to the comprehension of the neural underpinnings of tone processing, potentially enhancing intervention strategies. Moreover, they furnish a theoretical foundation for the language development and rehabilitation of deaf children.
