Monitoring 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 کاملMeasuring spike train synchrony.
Estimating the degree of synchrony or reliability between two or more spike trains is a frequent task in both experimental and computational neuroscience. In recent years, many different methods have been proposed that typically compare the timing of spikes on a certain time scale to be optimized by the analyst. Here, we propose the ISI-distance, a simple complementary approach that extracts in...
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 کاملMeasuring multiple spike train synchrony.
Measures of multiple spike train synchrony are essential in order to study issues such as spike timing reliability, network synchronization, and neuronal coding. These measures can broadly be divided in multivariate measures and averages over bivariate measures. One of the most recent bivariate approaches, the ISI-distance, employs the ratio of instantaneous interspike intervals (ISIs). In this...
