visual place recognition
How the fan-shaped body can integrate differential familiarity for route following in desert ants
We suggest a mechanism that integrates the allocentric velocity of the animal (estimated by the fan-shaped body) and the scene familiarity (estimated by the mushroom body) to a target velocity that drives the behaviour of the animal.

How do backward-walking ants (Cataglyphis velox) cope with navigational uncertainty?
Backward-walking ants can steer using learnt terrestrial visual cues.
Steering does not require forward body alignment.
Steering may be based on the integration of attractive and repulsive views.
Peeking behaviour is triggered in periods of low directional certainty.
Directional certainty is built on multiple sources of current and past information.
Insect neuroethology of reinforcement learning
Thesis - Doctor of Philosophy. I inversigated how insects form associative memories in their mushroom bodies and how this impacts their olfactory learning, visual navigation, and time-delayed reinforcements tasks.
