CSD Toolbox: MatLab implementation of a spherical spline algorithm (Perrin et al., 1989) to compute scalp surface Laplacian or current source density (CSD) estimates for surface potentials (EEG/ERP)

erpPCA: MatLab implementation of BMDP-4M algorithms (Dixon, 1992) for temporal PCA of ERP data, using the covariance matrix for factor extraction and covariance loadings for unrestricted Varimax rotation (Kaiser’s normalization)

PolyRex: General purpose converter of BioSemi's 24-bit data format (*.bdf) to NeuroScan's 16-bit data format (*.cnt)

TST: PC-based version of a simple tone screening test requiring pitch discrimination and sustained attention originally developed by Wexler et al. (1998) for use with a Macintosh computer

eBridge: Matlab function to identify channels in a continuous or epoched EEG recording that are linked by low-impedance electrical bridges
