| Research Abstract |
Recently, simultaneous recordings of multiple neuronal activities in the brain have become popular and those studies have provided new insights for the manner of information processing at the neuronal network level. Especially, much attention has been attracted on the precise temporal correlation in spiking activities among multiple neurons. Those characteristics are thought to become a key concept in understanding the information coding in the brain. In the current study, we provided a novel statistical method for analyzing non-stationary modulation of spike timing correlation between the two neurons, and successfully applied it to the experimental data.
