A new correlation-based measure of spike timing reliability
We introduce a new correlation-based measure of spike timing reliability. Unlike other measures, it does not require the definition of a posteriori "events". It relies on only one parameter, which relates to the timescale of spike timing precision. We test the measure on surrogate data sets with varying amounts of spike time jitter, and missing or additional spikes, and compare it with a widely...
متن کاملHow spurious correlations affect a correlation-based measure of spike timing reliability
The spike timing reliability of a neuron can be assessed via measuring the similarity of spike trains obtained in trials with repeated presentations of the same stimulus. Using a correlation-based measure of spike timing reliability we show that spurious correlations between independent Poisson spike trains can lead to a systematic misinterpretation to an extent that scales with the neural spik...
متن کاملReliability of spike timing in neocortical neurons.
It is not known whether the variability of neural activity in the cerebral cortex carries information or reflects noisy underlying mechanisms. In an examination of the reliability of spike generation using recordings from neurons in rat neocortical slices, the precision of spike timing was found to depend on stimulus transients. Constant stimuli led to imprecise spike trains, whereas stimuli wi...

متن کاملCorrelation based learning from spike timing dependent plasticity
We explore a synaptic plasticity model where potentiation and depression are induced by precisely timed pairs of synaptic events and postsynaptic spikes. We include the observation that strong synapses undergo relatively less potentiation than weak synapses, whereas depression is independent of synaptic strength. After random stimulation the synaptic weights reach a stable equilibrium distribut...
