[BIC-announce] Major update: Multiscale electrophysiology now in Brainstorm.

[Sylvain Baillet, Dr]

Hi everyone:

Just released: a considerable extension of our beloved Brainstorm app to basic electrophysiology, from single probes to dense-array recordings. We hope this responds to a major unmet need from the community in terms of user-friendly, free, open software that is well-supported & documented.

https://www.nature.com/articles/s41597-019-0242-z

The app supports a wide diversity of data formats for import/export, incl. BIDS, NeurodataWB, and the new Neuralink probes + MRI / CT volumes.

One convenient and much-useful feature is that Brainstorm now interoperates via GUIs, with leading apps for supervised and unsupervised spike detection and clustering: Waveclus. UltraMegaSort2000, and Kilosort/Klusters.

LFPs are extracted from original signal traces, after applying robust de-spiking (Zanos et al., 2011) + notch + anti-aliasing filtering + downsampling.

LFP traces can then be processed using the extensive toolkit library from Brainstorm, featuring e.g., spectral & time-frequency decompositions, connectivity estimates, inferential statistics, ML decoding, etc. ... and of course, new e-phys tools more specific to spike/LFP analytics incl.: raster plots, PSTH, tuning curves, noise correlations, spike-field coherence, etc.

For those of you who also collect anatomical images such as MRIs, Brainstorm features powerful solutions for 3D and slice visualization, with registration of electrode/array locations + e-phys data.

Thanks to all co-authors involved - a collaboration with the Peyrache and Pack labs @ MNI.

Looking forward to your feedback!

Best wishes,

Sylvain.
