Complex dynamics of V1 population responses explained by a simple gain-control model (2009, unknown): “In particular, this family of models can explain response saturation (Albrecht and Hamilton, 1982), contrastinvariant tuning (Sclar and Freeman, 1982; Skottun et al., 1987 Albrecht and Geisler, 1991), and phase advance of response a high stimulus contrasts (Carandini et al.”

Mechanisms for Stable, Robust, and Adaptive Development of Orientation Maps in the Primary Visual Cortex (2013, background): “For example, contrast-gain control mechanisms have been proposed to be involved in contrast-invariant tuning, whereby the tuning curves for V1 neurons retain the same width across contrasts (Sclar and Freeman, 1982; Skottun et al., 1987).”
Inhibition, spike threshold, and stimulus selectivity in primary visual cortex. (2008, unknown): “…tuning curves for orientation, as well as for other stimulus features, change very little in the face of large changes in stimulus contrast (Alitto and Usrey, 2004; Sclar and Freeman, 1982; Skottun et al., 1987), making these cells a model system for studying the mechanisms of tuning invariance.”
How Inhibition Shapes Cortical Activity (2011, unknown): “…visual cortex offer a classical example of gain modulation, where two independent properties of a visual stimulus, contrast, and orientation, interact in a multiplicative manner in generating spike output (Anderson et al., 2000; Carandini and Heeger, 1994; Miller, 2003; Sclar and Freeman, 1982).”
Orientation Selectivity in Macaque V1: Diversity and Laminar Dependence (2002, background): “This is because most illustrations of orientation tuning curves show curves without plateaus (Sclar and Freeman, 1982; Anderson et al., 2000).”

(2003, background): “In order to reproduce contrast invariance of orientation tuningThis intracellular study investigates synaptic mecha(Sclar and Freeman, 1982), this concept has been modi-nisms of orientation and direction selectivity in cat fied to include disynaptic intracortical inhibition actingarea 17.”
A Neural Implementation of the Kalman Filter (2009, background): “Interestingly, such a scaling, without a corresponding narrowing of tuning curves, is seen in the brain [20, 5, 2].”
Inference and computation with population codes. (2003, background): “This is true in particular in the case of orientation, or direction of motion, for which contrast is known to have a purely multiplicative effect (Dean 1981, McAdams & Maunsell 1999, Sclar & Freeman 1982, Skottun et al. 1987).”
Probabilistic population codes for Bayesian decision making (2008, background): “There is, however, a rather natural condition under which it is satisfied: c(tn) is contrast (Sclar and Freeman, 1982).”
