Activity Switching by External Signal in Neuron Ensembles, Modelling by Piecewise Linear Maps
K.V. Andreev and L.V. Krasichkov

Oscillatory activity switching in small neuron ensemble, modelling by piecewise linear maps, is considered. The ensemble under investigation consists of several clusters of globally coupled neurons connected in ring. The different types of activity switching by external pulse trains are shown. The areas of ``correct'' switching on the stimulus parameter planes are found. The biological interpretation of obtained results is discussed.
Key words: neuron, cluster, activity switching, spike, stimulus
