Information theoretic methods are now widely used for the analysis of spike train data. However, developing robust implementations of these methods can be tedious and time-consuming. In order to facilitate further adoption of these methods, the Spike Train Analysis Toolkit implements several information-theoretic spike train analysis techniques.
“The sensory-triggered activity of a neuron is typically characterized in terms of a tuning curve, which describes the neuron’s average response as a function of a parameter that characterizes a physical stimulus. What determines the shapes of tuning curves in a neuronal population?”
Information theory quantifies how much information a neural response carries about the stimulus. This can be compared to the information transferred in particular models of the stimulus-response function and to maximum possible information transfer. Such comparisons are crucial because they validate assumptions present in any neurophysiological analysis.
The authors review information-theory basics before demonstrating its use in neural coding, validating simple stimulus-response models of neural coding of dynamic stimuli.

The nervous system represents time-dependent signals in sequences of discrete action potentials or spikes, all spikes are identical so that information is carried only in the spike arrival times.
