Objectives

Narrative objectives1

Transcranial Magnetic Stimulation is utilized to non-invasively modulate auditory cortical activity, independent of the inner ear, and quantitatively evaluate the functional connectivity of central auditory neural circuits in individuals with hearing impairment through Electroencephalogram analysis.

Interventions/Control_1

On the first day, an MRI measurement will be conducted, followed by brainwave (EEG) recording and transcranial magnetic stimulation with EEG recording in the primary auditory cortex within two months. The MRI measurement is expected to take approximately 30 minutes. For the EEG recording and TMS-EEG sessions, the process will include the attachment of the EEG cap (15 minutes), recording of brainwaves during task and rest conditions (40 minutes), and TMS-EEG recording (80 minutes, including conditions with TMS pulses and skin stimulation only). The total time required for the EEG and TMS-EEG recordings is estimated to be around 2 hours. There will be no observation period before or after the measurements.

Key inclusion criteria

For individuals with normal hearing, there should be no self-awareness of hearing impairment and no indication of hearing loss in the past five years of health checkups.
For individuals with hearing impairment, they will be classified into one of the following categories based on their hearing test results: mild hearing loss (25 dB or more and less than 40 dB), moderate hearing loss (40 dB or more and less than 70 dB), severe hearing loss (70 dB or more and less than 90 dB), or profound hearing loss (90 dB or more).
No history of neurological disorders.
Must have a physique that allows for wearing headgear.

Key exclusion criteria

Have difficulty understanding explanations or instructions due to cognitive impairments.
Have a history of organic brain disorders or neurological diseases in the family.
Have a pacemaker implanted.
Already have a cochlear implant.
Have non-ferromagnetic materials in the body that cannot be confirmed to be non-magnetic (such as aneurysm clips, mechanical heart valves, neural stimulation devices, insulin pumps, intraocular metals, etc.).
If deemed unsuitable based on the "Transcranial Magnetic Stimulation (TMS) Examination Pre-checklist" and the "MRI Examination Pre-checklist."
Any other individuals deemed inappropriate as research subjects by the principal investigator.
