Generation of the respiratory rhythm: state-dependency and switching
Two alternative concepts have been o ered to explain the neural mechanisms responsible for the generation of the respiratory motor pattern in the brainstem: a network paradigm and...

Point-conductance models of cortical neurons with high discharge variability
Recent in vivo intracellular measurements indicate that cortical neurons operate in a highconductance state mainly caused by intense network activity. Biophysical models of morpho...

Novel dynamics of dendritic integration in the high conductance state of cortical neurons
Neocortical neurons in vivo operate in a high-conductance state which may a ect the dynamics of dendritic integration, but this aspect remains only barely characterized. We invest...

Information transmission by stochastic synapses with short-term depression: neural coding and optimization
The ability of dynamic synapses with short-term depression to transmit the information present in the presynaptic spike train to the postsynaptic neuron is discussed. Both by mini...

Optimal spontaneous activity in neural network modeling
We consider the origin of the high-dimensional input space as a variable which can be optimized before or during neuronal learning. This set of variables acts as a translation on ...

Recognizing the gist of a visual scene: possible perceptual and neural mechanisms
We try to understand the basics of human image processing from a gist recognition per-7 spective. Because the gist is only a subset of the image's information, we think that ...

Nonlinear model predictive control of a cutting process
Nonlinear model predictive control (MPC) of a simulated chaotic cutting process is presented. The nonlinear MPC combines a neural-network model and a genetic-algorithm-based optim...

Power and the limits of reactive agents
In this paper I will show how reactive agents can solve relatively complex tasks without requiring any internal state and I will demonstrate that this is due to their ability to c...
