Analyzing neural dynamics by considering higher-order interaction, and also the 
effect of time on reward prediction 

In my talk, I report two lines of research-in-progress of my laboratory. First, 
we present our analysis of neural activity interaction, including higher-order 
ones, partly based on information geometry. Second, we discuss our analysis of 
the effect of time representation of reinforcement learning for value-based 
decision-making and dopamine neural activity.
