We study the reconstruction of visual stimuli from spike trains, representing the reconstructed stimulus by a Volterra series up to second order. We illustrate this procedure in a prominent example of spiking neurons, recording simultaneously from the two H1 neurons located in the lobula plate of the fly Chrysomya megacephala. The fly views two types of(More)
We dynamically analyze our experimental results on the motion sensitive spiking H1 neuron of the fly's visual system. We find that the fly uses an alphabet composed of a few letters to encode the information contained in the stimulus. The alphabet dynamics is multifractal both with and without stimulus, though the multifractality increases with the stimulus(More)
Running head: Neural code of spike trains. ABSTRACT Sensory systems take continuously varying stimuli as their input and encode features relevant for the organism's survival into a sequence of action potentials-spike trains. The full dynamic range of complex dynamical inputs has to be compressed into a set of discrete spike times and the question, facing(More)
