Real-time cortical simulations: energy and interconnect scaling on distributed systems
Francesco Simula, Elena Pastorelli, Pier Stanislao Paolucci +11
We profile the impact of computation and inter-processor communication on the energy consumption and on the scaling of cortical simulations approaching the real-time regime on dist…
Sleep-like slow oscillations improve visual classification through synaptic homeostasis and memory association in a thalamo-cortical model
Cristiano Capone, Elena Pastorelli, Bruno Golosio +1
The occurrence of sleep passed through the evolutionary sieve and is widespread in animal species. Sleep is known to be beneficial to cognitive and mnemonic tasks, while chronic sl…
Cholinergic switch between two types of slow waves in cerebral cortex
Trang-Anh E. Nghiem, Núria Tort-Colet, Tomasz Górski +8
Sleep slow waves are known to participate in memory consolidation, yet slow waves occurring under anesthesia present no positive effects on memory. Here, we shed light onto this pa…
State equation from the spectral structure of human brain activity
Trang-Anh Nghiem, Jean-Marc Lina, Matteo di Volo +4
Neural electromagnetic (EM) signals recorded non-invasively from individual human subjects vary in complexity and magnitude. Nonetheless, variation in neural activity has been diff…
Spontaneous activity emerging from an inferred network model captures complex temporal dynamics of spiking data
Cristiano Capone, Guido Gigante, Paolo Del Giudice
The combination of new recording techniques in neuroscience and powerful inference methods recently held the promise to recover useful effective models, at the single neuron or net…
