Abstract
The striatum receives inputs from the whole cortex and is thought to process them for action selection, action execution and post-hoc action evaluation. In order to understand the striatal function, it is important to analyze the properties of spike train transaction from the cortex to the striatum. Normally, the spike correlation in different neurons is measured by using constant time scales. However, here we introduce a physiological time-scale difference between the cortex and the striatum, suggesting that the transactions involve a time-scale conversion of the spike train stream. To analyze the spike trains containing different time-scale correlation, it is necessary to develop new methods. In this symposium, we hope to discuss new approaches to the time-scale diversity of spike trains.
