PhD offer in Paris South: Modeling and steering brain oscillations based on in vivo optogenetics data

by Antoine Chaillet

Antoine Chaillet, Alain Destexhe and Mario Sigalotti are proposing a PhD entitled "Modeling and steering brain oscillations based on in vivo optogenetics data", at the interface between control theory and computational neuroscience. Candidates should contact antoine.chaillet(a)centralesupelec.fr for more information. Description: Neuronal oscillations are ubiquitous in the brain, both in health and disease. Nonetheless, the precise role of these oscillations is still a matter of debate, and the mechanisms by which they are generated are still poorly understood. Technological advances offer unprecedented ways to acquire and influence these oscillations. Electrode arrays and electrodes with dense recording plots now provide excellent spatiotemporal resolution of local brain activity. Moreover, the recent advent of optogenetics is revolutionizing the way of stimulating brain structures. The combination of electrophysiological recordings and optogenetics is thus particularly appealing to decipher the mechanisms of oscillation generation, their role in brain functioning, and the development of closed-loop strategies to steer brain oscillations (especially pathological ones). This project aims at developing and validating ad hoc methodologies to model, identify, analyze and control brain oscillations with these experimental tools. The challenges in that direction are numerous due to the nonlinear and spatiotemporal nature of the processes involved. To address these challenges, this project proposes to adapt or develop methodologies from control theory to the brain dynamics specificities. The performance of the developed methodologies will be confronted to experimental data of pathological oscillations linked to parkinsonian symptoms, that were collected on healthy and parkinsonian primates under optogenetics in the ANR project SynchNeuro. The aim of this PhD thesis is to develop a methodological framework, based on control engineering, to address three challenges: 1) development of a spatiotemporal model of specific brain oscillations, whose parameters are identified based on experimental data 2) formal analysis of brain oscillations onset and characterization of their dynamics in terms of magnitude, frequency and phase 3) development of closed-loop photostimulation strategies to disrupt, attenuate, or steer brain oscillations. Supervision: The PhD thesis will be supervised by Antoine Chaillet (L2S), in collaboration with Alain Destexhe (UNIC) and Mario Sigalotti (CMAP). It will take place in Gif sur Yvette (south of Paris), France. Sought candidate: We are looking for a brilliant motivated student, eager to work on an interdisciplinary topic. Strong background in dynamical systems is needed, as well as interest for theoretical developments. Experience in identification based on experimental data, or numerical simulations would be appreciated. No French ability is required. Antoine Chaillet Associate Professor Univ.

Three neuroinformatics positions in ferret brain research

by Rembrandt Bakker

(apologies for any cross-postings) In a collaboration between University Medical Center Eppendorf (Hamburg, Germany), the Donders Institute (Radboud University Nijmegen, The Netherlands), and Institute Pasteur (Paris, France), three positions at the postdoc level are available. The research focuses on studying the architecture and connectivity of the ferret brain, encompassing research on architecture and morphology (particularly, cortical folding) of the developing brain as well as the collation and analysis of brain connectivity in the adult brain. The project will make available a public data set of MRI and microscopic images of the developing ferret brain, together with tools for the online annotation of these data. The Nijmegen and Paris components of the research both develop the tools and perform an initial analysis of the MRI and microscopy data. The Hamburg component continues the development of a public online database of brain connectivity in conjunction with the development of an atlas of the adult ferret brain. The three positions are described in detail below. 1. Position at Radboud University. The full text of this position is available here: https://www.academictransfer.com/employer/RUN/vacancy/32519/lang/en/ The summary is: "We are looking for a highly motivated postdoctoral candidate to contribute to a neuroinformatics platform that allows researchers worldwide to jointly work on the creation of brain atlases. The scientific use case is to build a detailed developmental brain atlas for the ferret. The ferret is special in that the folding patterns of its brain develop after birth, so that the folding process can be studied on the basis of a series of combined MRI and microscopy data sets. Data will be provided by our partner Dr. Roberto Toro from Institute Pasteur in Paris, who is also the creator of the platform prototype (www.siphonophore.org/microdraw) You will work together with Dr. Rembrandt Bakker who leads the Scalable Brain Atlas project (www.scalablebrainatlas.org) The project is funded by the Netherlands Organization for Scientific Research (NWO) and its French counterpart and is part of a FLAG-ERA funding scheme that falls under the umbrella of the Human Brain Project. Further inquiries: r.bakker(a)fz-juelich.de, p.tiesinga(a)science.ru.nl 2. Position at University Medical Center Eppendorf, Hamburg, Germany We seek a Researcher in Neuroinformatics at the predoctoral or postdoctoral level, to curate an online database of ferret brain architecture and connectivity. The position is available immediately and runs until 30th June 2019. Further extensions are possible. The researcher will be expected to continue the conceptual and technical development of the ferretome.org database system, and supervise the population of the database with data collated from the literature as well as newly performed anatomy experiments. Moreover, the researcher will work on the integration of the ferretome with online atlases of the ferret brain. The researcher will be based at the Department of Computational Neuroscience, University Medical Center Eppendorf, Hamburg, Germany. The position is part of the Collaborative Research Center 936 (sfb936.net) âMulti-site communication in the brain" and would suit a researcher with background in computer science or biology. In any case, the position requires strong computer skills, particularly in database systems, high proficiency in written and spoken English and great curiosity. The researcher needs to integrate well with a highly multinational, multidisciplinary team at the Department of Computational Neuroscience as well as the Research Center 936. For researchers at the predoctoral level, the position offers the opportunity for obtaining a PhD degree. For further inquiries contact Prof. Claus C. Hilgetag, PhD: c.hilgetag(a)uke.de. 3. Position at Institute Pasteur This position at the postdoctoral level will commence after the microscopy data for the developmental ferret atlas has become available. The candidate should have a background in computational neuroanatomy or neuroinformatics, and preferrably have experience with online development and data visualisation. You will be working together with OphÃ©lie Foubet, who is doing a PhD that focuses on the mechanics of neocortical development.
