[Eeglablist] EEGLabList/Collaboration opportunity for EEG researcher/s

[David Mayor]

*Collaboration opportunity for EEG researcher/s with an interest in 
functional connectivity and/or (linear) frequency cepstral coefficients *

 From David Mayor and Tony Steffert (UK)


*Our project* investigates the effects of different frequencies of 
transcutaneous electroacupuncture stimulation (TEAS) applied to the 
hands. We are looking for EEG responses in the brain that may be related 
to the stimulation frequency (rather than just a volume conduction effect).

*Your collaboration* would involve using existing toolboxes to extract 
connectivity and/or frequency cepstral coefficients from around 2000 
pre-processed 5-minute 19-channel EEG recordings from 66 individuals. 
Other features could also be extracted, if agreed.

We envisage that one or more of the following packages could be used:

For those with the requisite skills, we anticipate that these tasks 
should not be too demanding!

*Data*, re-montaged using an average local reference and filtered 
between 0.5 and 45 Hz, mostly sampled at 500 Hz (although 32 files were 
sampled at 250 Hz). The 5-minute time series__data are available in .mat 
or .txt (csv) format, and 10-second segments in .txt (csv) format (10 
segments from each 5-minute recording, without overlap). The files are 
of two types, all recorded with eyes open – half were with pulsed 
biphasic square wave electrical stimulation to the hands (at 2.5, 10, 80 
or 160 pulses per second), and half without the stimulation. (Further 
description of the data may be found in Uyulan et al. 2023, 
https://urldefense.com/v3/__https://doi.org/10.3390/app13042703__;!!Mih3wA!F40g07mi4RnEVxdVu-imYksC0B5blVTu_r8rBkqGpf7fJu8zIWkTyX_1LA1PK0ufEKEICFLOnW5LIKJocXG_t8xTuC3KFuNIkFVW0A$ .)

*Publication. *We can offer co-authorship for one or more papers in 
appropriate open-access journals, but as independent researchers are not 
in a position to be able to pay for the work carried out.

*About us:* We (David Mayor and Tony Steffert) have been working 
together on this since 2011, with a number of papers already published 
and more in the pipeline. (You can read more at

2017, we organised a Brainstorm workshop for Sylvain Baillet and 
François Tadel at the Medical Research Council Cognition and Brain 
Sciences Unit in Cambridge, England. We are currently both visiting 
Fellows at universities in the UK (DM at the University of 
Hertfordshire, TS at the Open University).
