fNIRS Dataset during Hand-gripping Activity

The dataset comprises functional near-infrared spectroscopy (fNIRS) recordings of hand-gripping motor activity. The data is provided in three forms:

1. Raw Data: Unprocessed optical density values recorded using the nirSpot-2 system.
2. Processed Data: Data converted into oxy-hemoglobin (HbO) and deoxy-hemoglobin (HbR) concentration changes using standard preprocessing techniques.
3. Labeled Data: A fully processed and labeled version of the dataset, facilitating classification tasks.

Further details regarding the dataset, including acquisition methodology, preprocessing steps, and potential applications, are provided in the manuscript:
