Descriptif

Conférence de Audrey Dussutour (Université de Toulouse III - Paul Sabatier) dans le cadre du Colloquium du département d'Etudes Cognitives de l'ENS-PSL.

Learning and decision making have hitherto been investigated almost exclusively in multicellular neural organisms. Yet, evidence for learning and decision making have been described in single celled organisms : ciliates and slime molds for instance. In this conference, in the first part of my talk, I will focus on decision making in slime molds and explore various frameworks: nutritional geometry, speed versus accuracy trade-off, Weber's law and social influence. In the second part of my talk, I will show that habituation, a simple form of learning, can be observed in slime molds and may rely on simple mechanisms. Hopefully by the end of my talk, you will be convinced that slime molds are an ideal model system in which to investigate fundamental mechanisms underlying the ground-floor of cognitive abilities.

Cursus :

Audrey Dussutour est biologiste, chargée de recherche au CNRS.

Après avoir obtenu un doctorat d’éthologie en 2004, elle a effectué deux post-doctorats au Canada et en Australie, puis a été recrutée comme chercheure au CNRS en 2009. Depuis, elle travaille au Centre de recherches sur la cognition animale (CRCA – CNRS ; Université Toulouse III – Paul Sabatier). Son objectif de recherche est de comprendre comment des systèmes distribués, qu’ils soient des colonies de fourmis ou des organismes unicellulaires, interagissent avec leur environnement.
