....neural networks are developed by a genetic algorithm [9] to maximize a behavioral performance measure, and their resulting networks and dynamics are subjected to further study. EAAs are a very promising model for studying neural processing due to their simplicity, and their emergent architecture [5, 11]. Investigating spiky neural networks in this framework raises new ques tions, that were not raised using pre designed spiky models. For Example, evolutionary robotics studies have previously analyzed whether the spiking dynamics result in a time dependent or a rate dependent computation, and ....

Due to space limitations, we omitted this section from this version of the paper; this section will be included in a more comprehensive version, which is in preparation. 5. 2 Unexpected Behavior By and large, the behavior we encountered in the executions of the model followed our expectations, except for one case: we found that the Thelpercell object could not reach a steady Memory state.

....encountered in the executions of the model followed our expectations, except for one case: we found that the Thelpercell object could not reach a steady Memory state. The moment a T cell took the transition from Active to Memory, it returned right back to the Active state. This happened becanse IL 2 molecules were still in the system, while the Thelpercells, being in their Active state, expressed their IL2R component objects. As shown in Fig. 2, the event of IL 2 binding by the 11 2 receptor triggers the transition from the nonActive super state to the Active state. Only after an extensive ....

....into the model making it more realistic. In particular, cell description at the functional expression level is important since a recent microarray technology generates extensive protein expression data. Following this trend, cell description at the level higher than macromolecules such as modules [5] and hyperstructures [6] has been proposed. Modules are made up of many species of interacting molecules and carry out a specific cellular function, say, signal transmission. Hyperstructures may include assemblies of genes, mRNA, enzymes and lipids brought together to fulfil a particular function ....

....explainable in terms of known scientific principles. The second and third, however suggest that the kind of reductionism that helped to bring science to its present state will not necessarily be enough to enable human understanding of these fields. In the context of cell biology Hartwell et al.[35] have argued that progress will be more rapid and understanding more useful if researchers think in terms of functional units with inputs and outputs, each very much less complex than an entire cell but each more encompassing than a few related biochemical processes. This point of view involving ....
