Cortical neurons receive synaptic inputs from thousands of afferents that fire action potentials
at rates ranging from less than 1 hertz to more than 200 hertz. Both the number of afferents …

Hebbian models of development and learning require both activity-dependent synaptic
plasticity and a mechanism that induces competition between different synapses. One form of …

Synaptic plasticity provides the basis for most models of learning, memory and development
in neural circuits. To generate realistic results, synapse-specific Hebbian forms of plasticity, …

Neural circuits display complex activity patterns both spontaneously and when responding
to a stimulus or generating a motor output. How are these two forms of activity related? We …

Gain modulation is a prominent feature of neuronal activity recorded in behaving animals,
but the mechanism by which it occurs is unknown. By introducing a barrage of excitatory and …

The stability properties of Einstein theory with a cosmological constant Λ are investigated.
For Λ > 0, stability is established for small fluctuations, about the de Sitter background, …

We study the impact of correlated neuronal firing rate variability on the accuracy with which
an encoded quantity can be extracted from a population of neurons. Contrary to widespread …

In 1907, long before the mechanisms responsible for the generation of neuronal action
potentials were known, Lapicque developed a neuron model that is still widely used today [3, 7]. …

We use a mean-field approach to analyze the stability of the asynchronous state in a population
of all-to-all, pulse-coupled, nonlinear oscillators. We determine the conditions that must …

The primary visual cortex (V1) is the first cortical area to receive visual input, and inferior
temporal (IT) areas are among the last along the ventral visual pathway. We recorded, in area …
