  Shunting inhibitory cellular neural networks (SICNNs) with continuous as well
as discontinuous external inputs are investigated. The descriptions of
homoclinic and heteroclinic motions are provided in the functional sense for
the multidimensional dynamics of SICNNs, and it is demonstrated that the
networks under investigation exhibit such motions. Homoclinic and heteroclinic
outputs that are asymptotic to quasi-periodic outputs are illustrated.
