TL;DR
This study explores how near-infrared spectroscopy can track brain development in children with cochlear implants, showing similar brain activity to hearing children.
Contribution
The study demonstrates that fNIRS can detect cortical maturation in implanted children, aligning with auditory and language improvements.
Findings
No statistical differences in cortical activation between implanted children and hearing children of the same hearing age.
Improvement in auditory perception and language performance was observed after cochlear implant use.
fNIRS is a promising tool for tracking cortical changes in children with and without implants.
Abstract
The auditory rehabilitation mechanism with cochlear implants can activate specific cortical regions of the brain similar to those of hearing people. Near-infrared spectroscopy (fNIRS) is a neuroimaging tool that makes it possible to evaluate the cortical development of implanted children. Objective: To investigate the molecular imaging response, reflected by difference in cortical oxygenation, in a deaf child with a cochlear implant compared to hearing children, observe and report auditory performance verifying correspondence with fNIRS findings. Methods: Comparative case study using the fNIRS technique to evaluate the child's cortical activation on the day of device activation with three hearing children of the same hearing age. The recorded data was processed with Brainstorm software and statistical analysis was performed with the Power F test in relation to the baseline and the…
