  • Davies, Alex; Louis, Matthieu; Webb, Barbara (Public Library of Science (PLoS), 2015)
    Detailed observations of larval Drosophila chemotaxis have characterised the relationship between the odour gradient and the runs, head casts and turns made by the animal. We use a computational model to test whether ...
  • Schulze, Aljoscha (Universitat Pompeu Fabra, 2018-04-17)
    Animals have to deal with an environment presenting vast amounts of ever-changing sensory information. What features of this information flow are captured by the sensory system? My thesis work examines how signals experienced ...
  • Fink, Elie Marina-Lora (Universitat Pompeu Fabra, 2018-12-14)
    This thesis work explores the diversity of olfactory behaviour of Drosophila species in a comparative approach. We identify differences in the levels of attraction of the larva of eight species, towards natural odours ...
  • Schulze, Aljoscha, 1980-; Gómez Marín, Alex; Rajendran, Vani G.; Lott, Gus; Musy, Marco; Ahammad, Parvez; Deogade, Ajinkya, 1989-; Sharpe, James; Riedl, Julia, 1981-; Jarriault, David; Trautman, Eric T.; Werner, Christopher; Venkadesan, Madhusudhan; Druckmann, Shaul; Jayaraman, Vivek; Louis, Matthieu (eLife, 2015)
    Behavioral strategies employed for chemotaxis have been described across phyla, but the sensorimotor basis of this phenomenon has seldom been studied in naturalistic contexts. Here, we examine how signals experienced during ...
  • Deogade, Ajinkya (Universitat Pompeu Fabra, 2019-01-25)
    Chemotaxis is a powerful paradigm to study how sensory stimulations drive orientation behaviors in an organism. Drosophila larvae navigate odor gradients by controlling the duration of runs and the direction of turns. A ...
  • Riedl, Julia (Universitat Pompeu Fabra, 2014-10-31)
    En este estudio hemos aprovechado la simplicidad numérica del sistema nervioso de la larva de la Drosophila melanogaster para identificar las neuronas responsables que dirigen sus movimientos de acuerdo a ciertas sustancias ...
  • Braun, Andreas (Universitat Pompeu Fabra, 2018-05-30)
    Numerous studies have shown that a wide range of behaviors from sensory processing to motor control involve near-optimal probabilistic inference. Most of these studies have focused on vertebrates, suggesting that the ability ...
  • Tastekin, Ibrahim, 1986-; Riedl, Julia, 1981-; Schilling-Kurz, Verena; Gómez Marín, Alex; Truman, James W.; Louis, Matthieu (Elsevier, 2015)
    Chemotaxis is a powerful paradigm to investigate how nervous systems represent and integrate changes in sensory signals to direct navigational decisions. In the Drosophila melanogaster larva, chemotaxis mainly consists of ...
  • Tastekin, Ibrahim, 1986-; Khandelwal, Avinash, 1987-; Tadres, David; Fessner, Nico D.; Truman, James W.; Zlatic, Marta; Cardona, Albert; Louis, Matthieu (eLife, 2018)
    Sensory navigation results from coordinated transitions between distinct behavioral programs. During chemotaxis in the Drosophila melanogaster larva, the detection of positive odor gradients extends runs while negative ...
  • Kim, Daeyeon; Alvarez, Mar; Lechuga, Laura M; Louis, Matthieu (eLife, 2017)
    Animals explore their environment to encounter suitable food resources. Despite its vital importance, this behavior puts individuals at risk by consuming limited internal energy during locomotion. We have developed a novel ...
  • Schleyer, Michael; Reid, Samuel F.; Pamir, Evren; Saumweber, Timo; Paisios, Emmanouil; Davies, Alexander; Gerber, Bertram; Louis, Matthieu (Cold Spring Harbor Laboratory Press, 2015)
    How do animals adaptively integrate innate with learned behavioral tendencies? We tackle this question using chemotaxis as a paradigm. Chemotaxis in the Drosophila larva largely results from a sequence of runs and oriented ...
  • Almeida Carvalho, Maria J.; Braun, Andreas, 1983-; Louis, Matthieu; Zlatic, Marta (Company of Biologists, 2017)
    Mapping brain function to brain structure is a fundamental task for neuroscience. For such an endeavour, the Drosophila larva is simple enough to be tractable, yet complex enough to be interesting. It features about 10,000 ...
  • Tastekin, Ibrahim (Universitat Pompeu Fabra, 2018-07-19)
    The Drosophila larva is an excellent model organism to study the neural correlates of behavior. It possesses a tractable yet complex nervous system that is capable of integrating and transforming multimodal sensory stimuli ...
  • Berck, Matthew E.; Khandelwal, Avinash, 1987-; Claus, Lindsey; Hernandez-Nunez, Luiz; Si, Guangwei; Tabone, Christopher J.; Li, Feng; Truman, James W.; Fetter, Rick D.; Louis, Matthieu; Samuel, Aravinthan D. T.; Cardona, Albert (eLife, 2016)
    The sense of smell enables animals to react to long-distance cues according to learned and innate valences. Here, we have mapped with electron microscopy the complete wiring diagram of the Drosophila larval antennal lobe, ...
  • Khandelwal, Avinash (Universitat Pompeu Fabra, 2018-11-16)
    Drosophila larvae present unique opportunity for anatomical and functional mapping of their nervous system because of features such as numerical simplicity of neurons its nervous system is composed of, and ability to exhibit ...
