    International audience; We review and extend the previous work where a model was introduced for Hopfield-type neural networks, which allows for the existence of heteroclinic dynamics between steady patterns. This dynamics is a mathematical model of periodic or aperiodic...

    Author Summary Working memory is a cornerstone of intelligence. Most, if not all, tasks that one can imagine require some form of working memory. The optimal solution of a working memory task depends on information that was presented in the past, for example choosing th...

    Due to its inherent neural delays, the visual system has an outdated access to sensory information about the current position of moving objects. In contrast, living organisms are remarkably able to track and intercept moving objects under a large range of challenging en...

    International audience; Choosing an appropriate set of stimuli is essential to characterize the response of a sensory system to a particular functional dimension, such as the eye movement following the motion of a visual scene. Here, we describe a framework to generate ...

    Since the mid 1990s, the intriguing dynamics of the brain at rest has been attracting a growing body of/nresearch in neuroscience. Neuroimaging studies have revealed distinct functional networks that slowly/nactivate and deactivate, pointing to the existence of an under...

    Neurons in sensory areas of neocortex show responses tuned to specific features of the environment. In visual cortex, information about features such as edges or textures with particular orientations must be integrated to recognize a visual scene or object. Connectivity...

    Oscillations of the local field potential (LFP) are regarded as a signature of synchronized activity in neuronal networks. In primary motor (MI) and premotor (PM) cortex, LFPs typically exhibit such oscillatory activity in the beta range (15–30Hz) during an instructed d...

    In this study, we propose and analyze in simulations a new, highly flexible method of implementing synaptic plasticity in a wafer-scale, accelerated neuromorphic hardware system. The study focuses on globally modulated STDP, as a special use-case of this method. Flexibi...
