Alpha-Frequency Rhythms Desynchronize over Long Cortical Distances: A Modeling Study
Neocortical networks of excitatory and inhibitory neurons can display alpha()-frequency rhythms when an animal is in a resting or unfocused state. Unlike some - and -frequency rhy...

Learning sensory representations with intrinsic plasticity
Intrinsic plasticity (IP) refers to a neuron’s ability to regulate its firing activity by adapting its intrinsic excitability. Previously, we showed that model neurons combinin...

Solving Non-Boolean Satisfiability Problems with Stochastic Local Search
Much excitement has been generated by the success of stochastic local search procedures at finding solutions to large, very hard satisfiability problems. Many of the problems on wh...

A Sparse Generative Model of V1 Simple Cells with Intrinsic Plasticity
Current models for the learning of feature detectors work on two time scales: on a fast time scale the internal neurons' activations adapt to the current stimulus; on a slow ...

Wavebreaks and Self-termination of Spiral Waves in a Model of Human Atrial Tissue
We describe numerical simulations of spiral waves dynamics in the computational model of human atrial tissue with the CourtemancheRamirez-Nattel local kinetics. The spiral wave was...
