INS Seminars


We organize two types of seminars:

  • INS Keynote Seminars, giving “carte blanche” to prestigious speakers, invited to present a broad survey of their research achievements, in a format accessible to a non specialist audience of general systems and cognitive neuroscientists
  • INS Topical Seminars, which are more informal presentations aiming at introducing recent advancements in specific fields or illustrating technical approaches in more detail, always, of course, after a general introduction to the context and a fast survey of the state of the art.
For more informations, presentation material or proposing speakers to invite, please contact the INS seminars organizers:

Title : “Deciphering basal ganglia function using computational models”
Abstract :  Basal ganglia function can be addressed with computational modeling at different levels of abstractions. Here I demonstrate two such examples and an attempt to combine these models. Firsty, we address the question of what is the striatal representation of an motor action.  In order to investigate this issue, we designed a distance dependent spiking neuronal network model of the striatum consisting of D1 and D2 medium spiny neurons (MSNs) and interfaced it to a simulated robot moving in an environment. We demonstrate that this model is able to reproduce key behavioral features (freezing, ambulation and rotation) of 6 out of 7 optogenetic experiments that involved the manipulation of the striatum. The main result of this model was that D1 and D2-MSNs of an action co-operate whereas D1 and D2-MSNs of competing actions inhibit each other during action selection. Basal ganglia being a set of interacting nuclei and forming many functional pathways form a good substrate for degeneracy. This degeneracy might also explain the variability seen in the data in healthy as well as pathological conditions such as Parkinson’s disease. In order to investigate this issue, we model the basal ganglia as a firing rate model and perform a parameter search for effective connectivities between its nuclei for healthy and dopamine depleted conditions. The cost function used for constraining this system was derived from empirical firing rates and phase relationships as observed in healthy and dopamine depleted rats. We were able to generate more than 1000 physiological and pathological firing rate models that met the constraints and showed ample variability in the values of effective connectivities. We then projected these models onto a lower dimensional space of dynamical features such as : a) GPi suppression b) Susceptibiity to oscillations. Despite the large variability in effective connectivities, the models clustered together in this space and showed a clear separation between physiological and pathological conditions. This suggests that rather than absolute values of the effective connectivities, it might be their relative values that determine the dynamical state and projecting them on a lower dimensional space of sensible dynamical features might give a better chance at understanding complex pathologies such as Parkinson’s disease than a pure structural analysis. And lastly, we use these firing rate models to deconstruct basal ganglia transfer function in response to striatal optogenetic stimulation in order to explain one of the optogenetic experiments that we failed to explain in the first study.
