Table 1. 
Synaptic weight-dependent definition of memory and different forms of functional organization of two interconnected neuronal populations. The different functional organizations are defined based on the average excitatory synaptic weights ω~11, ω~22, ω~21, and ω~12 at equilibrium in relation to the average inhibitory synaptic weights (θ~).
