“…Although they were originally introduced as computational models, their biologically inspired structure and functioning, together with their feasibility as models of cellular and biomolecular processes, turned out to be a widely applicable modeling technique in several domains, including medicine (for immunological processes [6], and cellular tissue healing [5]), economics [16], linguistics and computer science (computer graphics, cryptography, approximate solutions to optimization problems) [4], and, of course, biology (for mechanosensitive channels [1], respiration in bacteria, photosynthesis, the protein kinase C activation [3]). …”
