fNIRS and demographic data for 3- to 9-month infants with congenital sensorineural hearing loss

Auditory exposure plays a crucial role in shaping brain development, but little is known about whether and how an initial lack of auditory exposure might disrupt the development of functional network lateralization. We addressed this issue by acquiring functional near infrared spectroscopy data from infants aged 3–9 months with congenital sensorineural hearing loss (SNHL) and typically developing controls.

## Description of the data and file structure

fNIRS and demographic data were collected from 3–9-month-old infants with congenital SNHL and age-matched typically developing (TD) controls to examine developmental differences in brain network lateralization.

### Files and variables

**Description:** 

##### Variables

* group: Indicates the type of participant — infants with sensorineural hearing loss (SNHL) or typically developing (TD) controls.
* ID: A numerical identifier assigned to each infant.
* age: Age range in months of each infant.
* ABR: Auditory brainstem response (ABR) threshold values for each infant.

#### File: SNHL_nirs.zip

**Description:** fnirs data of infants with sensorineural hearing loss. Each .nirs file includes:

* **d**: data matrix (time × channels, raw light intensity)
*..., All data have been properly de-identified in accordance with applicable ethical and legal standards. I confirm that I obtained explicit informed consent from all participants for their de-identified data to be shared in a public repository. Personally identifiable information (PII), such as names or contact information, has been removed. Participants are represented using numeric IDs instead of names or other identifiers.
