Real-time computing without stable states: a new framework for neural computation based on perturbations

A key challenge for neural modeling is to explain how a continuous stream of multimodal input from a rapidly changing environment can be processed by stereotypical recurrent circuits of integrate-and-fire neurons in real time. We propose a new computationa ...

Characterization of reliability of spike timing in spinal interneurons during oscillating inputs

Jesper Ryge

The spike timing in rhythmically active interneurons in the mammalian spinal locomotor network varies from cycle to cycle. We tested the contribution from passive membrane properties to this variable firing pattern, by measuring the reliability of spike ti ...

Intrinsic Stabilization of Output Rates by Spike-Based Hebbian Learning

Wulfram Gerstner

We study analytically a model of long-term synaptic plasticity where synaptic changes are triggered by presynaptic spikes, postsynaptic spikes, and the time differences between pre- and postsynaptic spikes. We show that plasticity can lead to an intrinsic ...

Noise and the PSTH response to current transients II. Integrate-and-fire model with slow recovery and application to motoneuron data

Wulfram Gerstner

A generalized version of the integrate-and-fire model is presented that qualitatively reproduces firing rates and membrane trajectories of motoneurons. The description is based on the spike-response model and includes 3 different time constants: the passiv ...

Effect of noise on neuron transient response

Wulfram Gerstner

A good approximation to the integrate-and-fire model with diffusive noise can be obtained using a noisy threshold model. This allows the response of a population of noisy neurons to a current transient to be described using a linear filter. Here we apply t ...

Increased focal interictal discharges during specific cognitive tasks

Olaf Blanke

We present a patient with pharmacoresistant right temporal lobe epilepsy who showed a significant increase in focal interictal spikes in response to specific visuospatial tasks, Temporal spiking was particularly increased during immediate recall of visuosp ...

Hebbian learning and spiking neurons

Wulfram Gerstner

A correlation-based (

Hebbian'') learning rule at the spike level is formulated, mathematically analyzed, and compared with learning in a firing-rate description. As for spike coding, we take advantage of a

learning window'' that describes the effect of ...

Noise-shaping in populations of coupled model neurons

Wulfram Gerstner

Biological information-processing systems, such as populations of sensory and motor neurons, may use correlations between the firings of individual elements to obtain lower noise levels and a systemwide performance improvement in the dynamic range or the s ...

Neural codes: firing rates and beyond

Wulfram Gerstner, Henry Markram

Computational neuroscience has contributed significantly to our understanding of higher brain function by combining experimental neurobiology, psychophysics, modeling, and mathematical analysis. This article reviews recent advances in a key area: neural co ...
