Selective attention implemented with dynamic synapses and integrate-and-fire neurons
Selective attention is a process widely used by biological sensory systems to overcome the problem of limited parallel processing capacity: salient subregions of the input stimuli...

Predicting synchronized neural assemblies from experimentally estimated phase-resetting curves
Neural-network dynamics frequently organize in assemblies of synchronized neurons that are thought to encode and store sensory information. We have investigated the mechanisms lea...

Eye movement predictions on natural videos
We analyze the predictability of eye movements of observers viewing dynamic scenes. We first assess the effectiveness of model-based prediction. The model is divided into inter-sa...

Evolving networks of integrate-and-fire neurons
This paper addresses the following question: ``What neural circuits can emulate the monosynaptic correlogram generated by a direct connection between two neurons?'' The ...

Prenatal development of ocular dominance and orientation maps in a self-organizing model of V1
How orientation and ocular-dominance maps develop before visual experience begins is controversial. Possible influences include molecular signals and spontaneous activity, but the...

Speed estimation with propagation maps
We propose a neural architecture that estimates the speed of motion. The basis is a two-dimensional map made of locally connected integrate-and-fire neurons, that propagates and i...

A novel approach to model neuronal signal transduction using stochastic differential equations
We introduce a new approach to model the behavior of neuronal signal transduction networks using stochastic differential equations. We present first a mathematical formulation for...

The interaction between facilitation and depression of two release mechanisms in a single synapse
The synapse from the lateral pyloric (LP) to the pyloric dilator (PD) neuron in the stomatogastric nervous system of the crab Cancer borealis has both a graded and a spike-mediate...
