Csd analysis
WebOne-dimensional CSD analysis is a practical and accurate method for defining both regional activity patterns and neural generators of surface-recorded evoked and event-related potentials. In computing the CSD, common practices of differentiating across spatial grids of 200 μm or more and use of spatial smoothing routines help to reduce noise ... WebCSD analysis can beperformed for signals in full spectrum or in any selected band, although it is usually applied to the low-frequency part (<500 Hz) of the extracellular …
