TL;DR: In this article, the authors measured neural variability in 13 extracellularly recorded datasets and one intra-cellularly recorded dataset from seven areas spanning the four cortical lobes in monkeys and cats and found that stimulus onset caused a decline in neural variability.

TL;DR: It is found that observed cell-to-cell variability in surround effects, from facilitation to suppression, can arise naturally from variability in the ISN, in which V1 operates as an inhibition-stabilized network (ISN), in which excitatory recurrence alone is strong enough to destabilize visual responses but feedback inhibition maintains stability.

TL;DR: High-contrast, orthogonally oriented stimuli that evoke significant depolarizations evoke few spikes, and these mechanisms, without lateral inhibition, can account for contrast-invariant stimulus selectivity.

TL;DR: Recorded intracellularly from a population of complex cells and found that the more MAX-like a cell was, the broader its spatial-frequency tuning as measured with drifting gratings, consistent with energy models in which classical complex cells receive input from simple cells with similar preferred spatial frequencies.
