Measuring and Modulating Changes in EEG Resting State Functional Connectivity During Short-term and Long-term Pain

Cutaneous pain was induced using a (5x10 cm) 8% topical capsaicin patch (transdermal patch, 'Qutenza', Astellas) on the volar part of the dominant right forearm (5 cm from the wrist) of each participant.

A transparent patch with no formulation or effect but the same size of the capsaicin patch was applied to the same location.
