SPIKY (Kreuz et al., 2015) is a graphical user interface written in Matlab which facilitates the analysis of electrophysiological data such as the EEG and neuronal spike trains (sequences of electrical action potentials emitted by neurons). In addition to the standard Peri-Stimulus Time Histogram (PSTH) it contains several time-resolved measures of spike train synchrony which were all developed in our lab: ISI-distance, SPIKE-distance, and SPIKE synchronization.
For a given data set SPIKY calculates the measures of choice and allows the user to switch between many different visualizations such as dissimilarity profiles, pairwise dissimilarity matrices, or hierarchical cluster trees. SPIKY also includes a spike train generator and an event detector which makes it capable of analyzing continuous data. Finally, the SPIKY-package includes complementary programs for the automatized analysis of a large number of datasets and for the evaluation of the statistical significance of the results.
