Sensory Stimulation of Hand and Face: Controls, Full-face Transplants and Facial Lesion Subjects
Description
The present data folder will be published with the EEG data when the paper 'Delta waves as a sign of cortical plasticity after full-face transplantation' is accepted. This dataset includes clipped EEG data of 10 healthy volunteers, 3 full face transplant patients and 4 facial lesion patients. 4 different sensory stimuli were applied to people with the help of a brush. Stimulations were applied to the right hand, right lower face, left hand and left lower face regions. Details of stimulation given in "Step to reproduce" section.

Steps to reproduce
All recordings were taken with Nihon Kohden EEG device in the EEG laboratory in Akdeniz University Faculty of Medicine, Department of Neurology. The recordings were taken as unipolar at a sampling frequency of 200 Hz using 64-channel EEG cap consisting of Ag/AgCl electrodes specifically designed in accordance with the international 10-10 system. The cap was placed on the scalp of the individual with reference to the nasion, inion and preauricular points. Electrode gel was used to lower the skin impedance and increase conductivity. The technical specifications of the recording device are as follows: electrode impedance 100-5000 Ω, high-frequency (high pass) filter, 70 Hz, low-frequency (low pass) filter, 1 Hz, notch filter, 50 Hz and initial sensitivity in acquisitions is 7 μV/mm. The hand stimulus was performed on the palmar surface of the right and left hands, starting from the thumb to the little finger. Facial stimuli were applied with the help of a brush on the right and left lower face regions, except for the lip region. The EEG recording procedure for hand and face stimulation were recorded with a block design. The design contained one minute of stimulation and 30 seconds of rest. Subjects were asked to close their eyes and stay in a comfortable and stable position during the recording. Stim and Rest periods are trimmed by 5 seconds from the beginning and end of each block.
