SUMMARY:Conférence mensuelle (PhD seminar series) - Barbara Webb
DESCRIPTION:Venue : Centre Broca Nouvelle-Aquitaine \nNeural circuits for navigation in insects \n \nBarbara Webb\nProfessor of Biorobotics\nInstitute for Perception\, Action and Behaviour\nSchool of Informatics\nUniversity of Edinburgh\nhttp://blog.inf.ed.ac.uk/insectrobotics/ \nInvited by Bordeaux Neurocampus and NBA \nAbstract\nInsect navigation has been a focus of behavioural study for many years\, but the neural mechanisms are largely unknown. We have used computational modelling to bridge this gap\, by relating the computational requirements of navigational tasks to the type of computation offered by invertebrate brain circuits. We have shown that visual memory of passing views could be\nacquired by associative learning in the mushroom body neuropil\, and allow insects to recapitulate long routes. We have also proposed a circuit in the central complex neuropil that integrates sky compass and optic flow information on an outbound path and can thus steer the animal directly home. The models are strongly constrained by neuroanatomy\, and are tested in realistic agent and robot simulations. \nSelected publications\nStone\, Thomas\, et al. « An anatomically constrained model for path integration in the bee brain. » Current Biology 27.20 (2017): 3069-3085.\nhttps://www.sciencedirect.com/science/article/pii/S0960982217310904 \nLe Moël\, Florent\, et al. « The central complex as a potential substrate for vector based navigation. » Frontiers in psychology 10 (2019): 690.\nhttps://www.frontiersin.org/articles/10.3389/fpsyg.2019.00690/full \nArdin\, Paul\, et al. « Using an insect mushroom body circuit to encode route memory in complex natural environments. » PLoS computational biology 12.2 (2016): e1004683.\nhttps://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1004683 \n
