Title: Algorithms for modeling the visual system: From natural vision to numerical applications

Overview. The design of artificial sensory systems has evolved in parallel to our knowledge on biological systems. Although the field of engineering can take advantage of sensory biological solutions discovered in nature, only recently some bioinspired solutions for visual applications have emerged. In the last years and with the advent of new neural acquisition methods and theoretical frameworks a better understanding of the neural coding process - from physical signals to neural networks - has emerged (Simoncelli and Olshausen 2001, Hemmen and Sejnowski 2006). More particularly, a recent description in the retina of non-standard ganglion cells types, beside a complex repertoire of standard ganglion cells responses in front of natural stimulus convey important questions about the real, early processing capacity of the retina. This leads to revisit both the neural coding of the information the eye is sending to the brain, and also sheds light to engineering applications from the understanding of such encoding, as detailed in the sequel. At the modeling level, retinal cells are mainly formalized using a LN (Linear spatio-temporal filtering followed by a static Non-linear transduction), while an important fraction of non-standard cells response cannot be represented in such a model class. This is thus a challenge to develop an innovative formalism that takes such complex behaviors into account, with such immediate applications as new dynamical early-visual modules. Proposing new innovative bioinspired formalisms in order to perform dynamical visuo-perceptual tasks adapted to natural environment is a main goal of this project, with a special focus to scenes including complex visual motion interacting with light.
The project is a cooperation between the University of Nice (France), the University of Valparaiso (Chile), the Pontifical Catholic University of Chile in Santiago de Chile, CORTEX, MNEMOSYNE and NEUROSYS.

Sleep is an essential part of a healthy life, but many people – especially as they get older – have trouble getting enough uninterrupted sleep. There is much still to be learned about how we can fall asleep, stay asleep and wake up in a healthy way, and this is a promising area of research for LIRA. The aim of this project is to define physiological features that impact the quality of sleeping. Special sensors installed in a mobile phone or bed can analyze activities, stress patterns and sleep sequences and provide ideas for new strategies and, eventually, products that support a healthier night’s sleep. NEUROSYS has a Postdoc project running merging all sensor signals in a single data analysis technique to improve existing sleep monitors.

Overview. Oscillations are omnipresent in the brain, but their function is still disputed. In motor cortex, beta and gamma oscillations are often observed, but their proposed roles in sensorimotor behavior are largely overlapping. While much is known on the laminar distribution of oscillations in sensory areas, the very sparse data on the laminar profile of motor cortical oscillations largely limits their functional interpretations. Here we will study the layer specificity of monkey motor cortical oscillations and oscillatory interactions between M1 and PMd during visuomotor behavior. Extending conventional tools, such as coherency analysis, the team in Nancy will develop a new method to quantify short-­‐lasting partial amplitude and phase synchronization in single-­‐trial data, based on wavelets, exploiting the predefined vicinity of contacts on the laminar probes. The application of this new method to the data recorded in Marseille will reveal instantaneous amplitude and phase synchronization between cortical layers and between M1 and PMd, providing novel insights into the functional roles of beta and gamma oscillations in visuomotor behavior.
