Steering a ring attractor

In recent years we have started to learn about the circuitry that underpins spatial behaviour in insects. One of the most important findings has been that of a ring attractor circuit in the ellipsoid body of the central complex of insects. This circuit can represent heading and is updated via visual or proprioceptive information. Now, the understanding of how this ring-attractor works is expanding to the associated structures. Green et al. have detailed how specific neurons, in a brain areas connected to the ellipsoid body, are involved in the driving of neural activity in the ring attractor. This opens up the potential for us to understand how sensory input contributes to the neural representation of spatial information.
