A nonlinear recurrence involving a piecewise constant McCulloch-Pitts function and -periodic coefficient sequences is investigated. By allowing the threshold parameter to vary from 0 to , we work out a complete bifurcation analysis for the asymptotic behaviors of the corresponding solutions. Among other things, we show that each solution tends towards one of four different limits. Furthermore, the accompanying initial regions for each type of solutions can be determined. It is hoped that our analysis will provide motivation for further results for recurrent McCulloch-Pitts type neural networks.
