Here you can download software packages I developed.

Artifact removal method based on the wavelet enhanced Independent Component Analysis (wICA)

Original package: wICA

Updated Oct. 2012 (no extra packages are required): wICA_2

For details, see Castellanos N. P. and Makarov V. A. Recovering EEG brain signals: Artifact suppression with wavelet enhanced independent component analysis. Neurosci. Methods 158, 300-312, 2006.

Analysis of LFP generators (ICAofLFPs package for Matlab

Package v. 1.09 (Sept. 2021: some fixes): ICAofLFPs Package

Installation instruction: Reedme

Basic (short) help: Help for ICAofLFPs

Test data file: Sch_Lac_Aleat_mat (91 MB). This file contains raw LFPs and already found LFP-generators (you can play around and, e.g., crosscheck your generators with ours).

An example of a smr data file (Cambridge Electronic Design): Link to SMR (39 MB). The file has 32 channels of raw LFPs recorded from the rat hippocampus. Use «1 linear» for the electrode arrangement inside ICAofLFPs.
