A Novel Spike Distance
The discrimination between two spike trains is a fundamental problem for both experimentalists and the nervous system itself. We introduce a measure for the distance between two spike trains. The distance has a time constant as a parameter. Depending on this parameter, the distance interpolates between a coincidence detector and a rate difference counter. The dependence of the distance on noise...
متن کاملMeasuring spike train distance from multichannel spike trains data simulated by coupled escape rate model
Estimating the population activity patterns between two or more spike trains is a fundamental problem in studying neural coding in computational neuroscience. In recent years, there are many different methods proposed to build a framework to deal with these problems by using spike train metric. Here we suggest a kernel method for multichannel spike trains that can provide an opportunity to meas...
متن کاملMeasuring spike pattern reliability with the Lempel-Ziv-distance.
Spike train distance measures serve two purposes: to measure neuronal firing reliability, and to provide a metric with which spike trains can be classified. We introduce a novel spike train distance based on the Lempel-Ziv complexity that does not require the choice of arbitrary analysis parameters, is easy to implement, and computationally cheap. We determine firing reliability in vivo by calc...
متن کاملSpike train clustering using a Lempel-Ziv distance measure
Multi-electrode array recordings reveal complex structures in the firing of spatially distributed neurons. The analysis of this neuronal network activity demands a classification of neurons according to similarities in their firing behavior. If similar spike patterns do not occur synchronously, but have unknown delays within spike trains, this processing step is difficult. To solve this problem...
متن کاملEnhanced neural discrimination of sensory stimuli using an adaptive spike distance
It was once common to believe that the timing of spikes in spike trains was too variable to carry information and that in the sensory pathways information about stimuli was represented by spike rates. While it is now thought possible that stimuli are also represented in spike-timing features (Bialek et al., 1991; Rieke et al., 1999a; De Ruyer Van Steveninck et al., 1997; Borst and Theunissen, 1...
