Brainstorm: a user-friendly application for MEG/EEG analysis.

Tadel F, Baillet S, Mosher JC, Pantazis D, Leahy RM - Comput Intell Neurosci (2011)

Bottom Line: Brainstorm is a collaborative open-source application dedicated to magnetoencephalography (MEG) and electroencephalography (EEG) data visualization and processing, with an emphasis on cortical source estimation techniques and their integration with anatomical magnetic resonance imaging (MRI) data.The primary objective of the software is to connect MEG/EEG neuroscience investigators with both the best-established and cutting-edge methods through a simple and intuitive graphical user interface (GUI).

The primary objective of the software is to connect MEG/EEG neuroscience investigators with both the best-established and cutting-edge methods through a simple and intuitive graphical user interface (GUI).

Mentions: Brainstorm's “Process2” tab allows the comparison of two data samples. This corresponds to a single factor 2-level analysis and supported tests include simple difference, paired/unpaired Student t-tests of equal/unequal variance, and their nonparametric permutation alternatives [17]. The two groups can be assembled from any type of files, for example, two conditions within a subject, two conditions across subjects or two subjects for the same conditions, and so forth. These operations are generic in Brainstorm and can be applied to any type of data in the database: MEG/EEG recordings, source maps, and time-frequency decompositions. Furthermore, analysis of variance (ANOVA) tests are also supported up to 4 factors. Figure 15 displays the use of a Student t-test to compare two conditions, “GM” and “GMM,” across 16 subjects.
