process for the survival of 11.nim11-h,, however, its phenomenon is poorly understood.

Therefore, we do not inference on neuronal activity at a single spike level. In this paper, we made an assumption that groups of neurons become active simultaneously. We used non-negative matrix factorization (NMF) to identify those groups and their neuronal activities in time.
