visual place recognition

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.

• 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.

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.
