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:
EEG dynamic connectivity and microstates analysis [https://github.com/stdimitr] (the latter with supervision from Stavros Dimitriadis)
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://doi.org/10.3390/app13042703.)
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 http://electroacupuncture.qeeg.co.uk/.
DM is the author/editor of Elsevier’s textbook on electroacupuncture (http://www.electroacupunctureknowledge.com/), and TS an experienced qEEG neurofeedback practitioner and researcher (http://qeeg.co.uk/). In 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).
If you are interested in collaborating on this project or have any questions about it, please contact David Mayor before 1 October 2023.
