Analog Implementation of Shunting Neural Networks

The first case shows recurrent activity, while the second case is non-recurrent or feed forward. The polarity of these terms signify excitatory or inhibitory interactions. Shunting network equations can be derived from various sources such as the passive membrane equation with synaptic interaction (Grossberg 1973, Pinter 1983), models of dendritic interaction (RaIl 1977), or experiments on motoneurons (Ellias and Grossberg 1975).
