The Firing Pattern Properties in Retinal Ganglion Cells
The correlation between spike trains of chicken retinal ganglion cells recorded by the multi-electrode recording system are calculated by cross-correlation function and Lempel-Ziv distance. Cross-correlation evaluates the degree of neural synchronization while Lempel-Ziv distance measures the similarity of firing patterns. The results indicate that compared with synchronization, firing patterns show stronger coordination in neuron groups and reflect the stimuli property more accurately. Thus the measurement of spike train patterns by Lempel-Ziv distance can give us more comprehensive cognition and additional insights in neural coding analysis.
