Fluctuation-driven neural dynamics reproduce Drosophila locomotor patterns

Dario Floreano, Pavan P Ramdya, Kyle Gustafson, Andrea Maesani

The neural mechanisms determining the timing of even simple actions, such as when to walk or rest, are largely mysterious. One intriguing, but untested, hypothesis posits a role for ongoing activity fluctuations in neurons of central action selection circu ...

Swarm Robotic Plume Tracking for Intermittent and Time-Variant Odor Dispersion

Ali Marjovi

This paper presents a method for odor plume tracking by a swarm of robots in realistic conditions. In real world environments, the chemical concentration within an odor plume is patchy, intermittent and time-variant. This study shows that swarm robots can ...
