Time compensation in the celestial compass of insects
We propose a mechanism that can transform the sun’s position into a compass that points north.

Celestial compass sensor mimics the insect eye for navigation under cloudy and occluded skies
Editor’s Choice Paper 2023. Hardware prototype of the model using a ring of UV-sensitive photodiode pairs, and test it under cloudy and occluded skies.

Memory dynamics in Drosophila's mushroom body: a computational view
In this talk I present how our anatomically accurate incentive circuit predicts the responses of mushroom body neurons from the fruit fly brain and how they can be used to create similar behaviour to the one observed in the animals.

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 could the mushroom body and central complex combine for visual homing in insects?
We test the performance of the incentive circuit in the visual place recognition task and suggest that the familiarity must increase along a familiar route. Additionally, PCA whitenning and combinatorial encoding techniques enhanced the separability of visual scenes. The familiarity could be used as input to the central complex for visual homing.

Insect-brain inspired neuromorphic nanophotonics
The goal of the project is to develop nanophotonic on-chip devices for integrated sensing and neural computation, inspired by the insect brain.
An anatomically accurate circuit for short- and long-term motivational learning in fruit flies
We present how our novel dopaminergic learning rule and the incentive circuit predict the responses of mushroom body neurons from the fruit fly brain and create similar behaviour to the one observed in the animals.

An incentive circuit for memory dynamics in the mushroom body of Drosophila melanogaster
Modelling differential roles for identified dopaminergic and output neurons of the fruit-fly mushroom bodies combined with a novel dopaminergic plasticity rule explains neural and behavioural phenomena in olfactory learning tasks.

The incentive circuit of the fruit fly brain: a computational perspective
In this poster we show how our anatomically accurate incentive circuit predicts the responses of mushroom body neurons from the fruit fly brain and how they can be used to create similar behaviour to the one observed in the animals.
