Short-Term Memory and Its Biophysical Model

The capacity of short-term memory has been studied using an integrate-and-fire neuronal network model. It is found that the storage of events depend on the manner of the correlation between the events, and the capacity is dominated by the value of after-depolarization potential. There is a monotonic increasing relationship between the value of after-depolarization potential and the memory, numbers. The biophysics relevance of the network model is discussed and different kinds of the information processes are studied too.
