Using dopamine modulation of the 14‐neuron pyloric network from the crustacean stomatogastric ganglion as an example, two major mechanisms by which network output is modulated are described, emphasizing the distributed nature of modulation in motor networks.
Monoamine Control of the Pacemaker Kernel and Cycle Frequency in the Lobster Pyloric Network
The results show that the major target of 5HT in altering the pyloric cycle frequency is the AB neuron, whereas DA’s effects on the AB–2xPD subnetwork are critical in understanding its modulation of the cycle frequency.
Molecular Underpinnings of Motor Pattern Generation: Differential Targeting of Shal and Shaker in the Pyloric Motor System
A stereotypic distribution of channels is found in the cells, such that each channel type could contribute to different aspects of the firing properties of a cell, and it is concluded that the differential targeting of shaker and shal to different compartments is conserved among all the pyloric neurons.
Dopamine modulates graded and spike-evoked synaptic inhibition independently at single synapses in pyloric network of lobster.
It is concluded that DA can differentially modulate the spike-evoked and graded components of synapses between members of a central pattern generator network.
Process entanglement as a neuronal anchorage mechanism to rough surfaces
It is demonstrated that the roughness of the surface must match the diameter of the neuronal processes in order to allow them to bind, and entanglement, a mechanical effect, may constitute an additional mechanism by which neurons (and possibly other cell types) anchor themselves to rough surfaces.
Locust Collective Motion and Its Modeling
A wide range of recent modeling and simulation approaches are described, from discrete agent-based models of self-propelled particles to continuous models of integro-differential equations, aimed at describing and analyzing the fascinating phenomenon of locust collective motion.

The results suggest that differences in PKG enzyme activity are correlated to well-established phase-related behavioral differences, and lay the groundwork for functional studies of the locust for gene and its possible relations to locust phase polyphenism.

The desert locust is the model for the presented bio-inspired design of a jumping mechanism for a small mobile robot, and the basic mechanism is based on the cocking of a torsional spring by wrapping a tendon-like wire around the shaft of a miniature motor.

Intersegmental Coordination of Cockroach Locomotion: Adaptive Control of Centrally Coupled Pattern Generator Circuits
The two species of cockroach may exemplify opposite extremes of a fast–slow locomotion continuum, mediated through different intersegment coordination strategies, according to a combined experimental and theoretical approach.
