Analyzing Data From a Micro-Electrode Array From Multichannelsystems

Support & Discussions
1

I’m a computer science graduate-student that has been offered the opportunity to help a very small research group to improve their ability to analyze local field potentials. Currently, they are using “Multichannel analyzer” from “Multichannel systems”. However, they find the software limited (e.g. restrictions on band pass filters and limits to the size of time windows). Especially in the context of field potentials, but not applicable to analyzing action potentials.

They are using a 256 Micro-Electrode Array from Multichannel systems. My background in electrophysiology is limited, and therefore asking for suggestions for appropriate libraries to analyze field potentials. Is this something MNE can be used for? I have also looked at the Elephant library.

Thanks.

The analysis of local field potentials is not something that MNE-Python has native support for. Elephant seems like a more logic choice.

Thank you for the information. Any other suggestions that would be of use?

If you are willing/able to use MATLAB, FieldTrip has some ability to analyze LFPs: Preprocessing and analysis of spike and local field potential data - FieldTrip toolbox

I asked a similar question. The answer i was given was to use the RawArray object to create an object from your LFP data without requiring the standard EEG montage. The you can use the signal processing library of MNE for your LFP analysis.
