Innovative Methodology SPIKY: a graphical user interface for monitoring spike train synchrony
Kreuz T, Mulansky M, Bozanic N. SPIKY: a graphical user interface for monitoring spike train synchrony. J Neurophysiol 113: 3432–3445, 2015. First published March 5, 2015; doi:10.1152/jn.00848.2014.—Techniques for recording large-scale neuronal spiking activity are developing very fast. This leads to an increasing demand for algorithms capable of analyzing large amounts of experimental spike tr...
متن کاملMonitoring spike train synchrony
Recently, the SPIKE-distance has been proposed as a parameter-free and timescale-independent measure of spike train synchrony. This measure is time resolved since it relies on instantaneous estimates of spike train dissimilarity. However, its original definition led to spuriously high instantaneous values for eventlike firing patterns. Here we present a substantial improvement of this measure t...

متن کاملMeasures of spike train synchrony: From single neurons to populations
With the increasing availability of multi-unit recordings the focus of attention is shifting from bivariate estimators of spike train synchrony towards methods that describe patterns of activity across many neurons. Such measures of population spike train synchrony are becoming indispensable tools for addressing issues such as spike timing reliability, network synchronization, and neuronal codi...
متن کاملSurrogate Spike Train Generation Through Dithering in Operational Time
Detecting the excess of spike synchrony and testing its significance can not be done analytically for many types of spike trains and relies on adequate surrogate methods. The main challenge for these methods is to conserve certain features of the spike trains, the two most important being the firing rate and the inter-spike interval statistics. In this study we make use of operational time to i...
