Surround modulation (SM) is a fundamental property of sensory neurons in many species
and sensory modalities. SM is the ability of stimuli in the surround of a neuron's receptive …

The mechanisms underlying the emergence of orientation selectivity in the visual cortex
have been, and continue to be, the subjects of intense scrutiny. Orientation selectivity …

In macaque primary visual cortex (V1), neuronal responses to stimuli inside the receptive
field (RF) are modulated by stimuli in the RF surround. This modulation is orientation …

The population activity of random networks of excitatory and inhibitory leaky integrate-and-
fire neurons has been studied extensively. In particular, a state of asynchronous activity with …

Evidence suggests that the brain uses an operational set of canonical computations like
normalization, input filtering, and response gain enhancement via reentrant feedback. Here …

Highlights•Inhibition-stabilized networks describe the visual cortical operating
point.•Dynamic synapses cause nonlinearity and multi-stability in balanced …

A common feature of the mammalian striate cortex is the arrangement of 'orientation
domains' containing neurons preferring similar stimulus orientations. They are arranged as …

Most modeling in systems neuroscience has been descriptive where neural representations
such as 'receptive fields', have been found by statistically correlating neural activity to …

We use stochastic neural field theory to analyze the stimulus-dependent tuning of neural
variability in ring attractor networks. We apply perturbation methods to show how the neural …

The intrinsic functional architecture of early cortical areas in highly visual mammals is
characterized by the presence of domains and pinwheels, with orientation preference of the …
