This repository contains code associated with an ongoing project investigating changes in EEG spectral power induced by secondary hyperalgesia following High-Frequency Stimulation (HFS).
The analyses are conducted on two independent datasets from separate experiments and aim to:
- Assess whether HFS induces consistent changes in EEG spectral power across both datasets.
- Evaluate whether these spectral changes are associated with the extent of induced hyperalgesia.
The analyses are performed both before and after applying a surface Laplacian transformation to the EEG data, in order to assess whether the observed spectral changes likely originate from neural sources close to the scalp (e.g., S1/S2).
