Description The aim of this workshop is to establish a communication channel between the biomedical and mathematical communities and fostering collaborations between both communities. The talks will be given by mathematicians and physical scientists and will consist of informative, non-technical reports of their research activity regarding mathematical modelling of bio-medical problems which can be susceptible of possible further collaboration. Speakers: - Mariangeles Serrano, Dep. Quimica Fisica, Universidad de Barcelona, Modelling metabolic networks - Juan Soler, Dep. de Matematica Aplicada, Universidad de Granada, Morphogen modeling through flux-limited spreading - David Reguera, Dep. Fisica Fundamental, Universidad de Barcelona, Physical modelling of the structure and self-assembly of virus - Tomas Alarcon. Centre de Recerca Matematica. Modelling population dynamics in medical problems - Carme Calderer, Dep. Mathematics, University of MInnesotta, Polyelectrolyte gels with applications to the design of microfluidic devices

Description In this talk I will first discuss some of the cellular and network mechanisms that determine the generation and propagation of cortical rhythmic activity. Next, how rhythmicity and synchronicity are transformed when there is a transition to a different brain state or alteration of physiological variables such as temperature. An emphasis will be made on the cortical excitatory / inhibitory balance and how progressive alterations of this balance induces parametric alterations of rhythmicity (Sanchez-Vives et al., J Neurophys epub 2010). Progressive reduction of inhibition in the /in vitro/ cortical network induces linear changes in different parameters of Up and Down states, linearity that is lost when the activity becomes epileptiform. The mechanistic and connectivity rules that support our experimental findings are explored using a biologically inspired computer model of the cortical network.

Description Formation and specification of neurons during early embryo development is a tightly regulated process that combines spatial and temporal constrains. The process of differentiation of neural stem cells into committed neuronal subtypes integrates cell cycle control, cell movement and morphogenetic signals. The simple geometry of the neural tube and the dynamics of the process propitiate an interesting framework for physics and mathematicians to develop models and tools to understand the process. In this talk, I will explain the basics of neural tube formation and neuronal specification, together with some interesting experimental results that open new avenues in the study of vertebrate neurogenesis.
