The biological principles of swarm intelligence
The underlying mechanisms of complex collective behaviors of social insects, from the concept of stigmergy to the theory of self-organization in biological systems, are described and four functions that emerge at the level of the colony and that organize its global behavior are proposed.
Deciphering Interactions in Moving Animal Groups
Using video tracks of fish shoal in a tank, it is shown how a careful, incremental analysis at the local scale allows for the determination of the stimulus/response function governing an individual's moving decisions, yielding a novel schooling model whose parameters are all estimated from data.
Emergent polyethism as a consequence of increased colony size in insect societies.

It is found that increasing colony size while keeping the demand proportional to the colony size causes an increase in the differentiation among individuals in their activity levels, thus explaining the occurrence of elitism in insect societies.
Topological patterns in street networks of self-organized urban settlements
The global efficiency, robustness to disconnections and cost of these graphs is studied and their possible origins analyzed, finding a wide range of patterns, from tree-like settlements to meshed urban patterns.
Rate coding versus temporal order coding: a theoretical approach.
Rank order coding
The vast majority of neurophysiological studies simply describe neural responses in terms of firing rate, and while studies using Peri-Stimulus Time Histograms are fairly common, only rarely does one get to see the underlying spikes in the form of a raster display.
SpikeNET: A simulator for modeling large networks of integrate and fire neurons
Face processing using one spike per neurone.

This study demonstrates the synergy between the initiator's behaviour and the self-organized mechanisms underlying group movements, as well as the coupling between joining and cancellation rates, that leads to a quorum in white-faced capuchins.
Self-Organized Aggregation Triggers Collective Decision Making in a Group of Cockroach-Like Robots
It is demonstrated that the restriction of the self-amplified aggregation behavior to distinct zones in the environment can explain the emergence of a collective decision at the level of the group.
