AbstractExplaining the macroscopic activity of a recorded neuronal population from its known microscopic properties still poses a great challenge, not just because of the many local agents that shape the output of a circuit, but due to the impact of long-range connections from other brain regions. Here we use a computational model to explore how local and global components of a network shape the Slow Wave Activity (SWA).

AbstractExploring the dynamics of a complex system, such as the human brain, poses significant challenges due to inherent uncertainties and limited data. In this study, we enhance the capabilities of noisy linear recurrent neural networks (lRNNs) within the reservoir computing framework, demonstrating their effectiveness in creating autonomous in silico replicas - digital twins - of brain activity.

AbstractA general mathematical description of how the brain sequentially encodes knowledge remains elusive. We propose a linear solution for serial learning tasks, based on the concept of mixed selectivity in high-dimensional neural state spaces. In our framework, neural representations of items in a sequence are projected along a “geometric” mental line learned through classical conditioning.

– Bon aussi pour le porte-monnaieLes nouvelles technologies pour produire de l’électricité sont aussi une formidable opportunité pour notre tissu économique. Publié aujourd’hui à 06h50Les opposants à la loi climat soumise au vote le 18 juin, soit principalement l’UDC, tentent d’opposer la protection du climat avec la sauvegarde du porte-monnaie. Ces deux éléments vont pourtant de pair. Si les énergies fossiles sont pratiques à utiliser, elles ne sont en tout cas pas économiques.
