Mechanisms for Stable, Robust, and Adaptive Development of Orientation Maps in the Primary Visual Cortex (2013, methodology): “Similar methods of achieving contrast-invariant orientation tuning have been described in previous nondevelopmental models (Geisler and Albrecht, 1997; Anderson et al., 2000; Carandini et al., 2002; Finn et al., 2007), but to our knowledge GCAL is the first model to show how contrast-invariant tunin”
Divisive normalization in olfactory population codes (2010, background): “In other circuits the mechanisms of normalization may be different, and may not involve GABAergic inhibition (Carandini et al., 2002; Freeman et al., 2002).”
GABAA inhibition controls response gain in visual cortex (2011, unknown): “Normalization is now thought to rely on alternative mechanisms, at least for phenomena that arise within the receptive field (Carandini et al., 2002; Priebe and Ferster, 2006; Finn et al., 2007).”
The emergence of contrast-invariant orientation tuning in simple cells of cat visual cortex. (2007, background): “Possible sources for the early simple-cell contrast saturation include depolarization-induced reductions in driving force on synaptic currents, and activity-dependent synaptic depression (Carandini et al., 2002; Kayser et al., 2001), which can reach nearly 50% in geniculocortical synapses (Bannister”
Predictive Coding as a Model of Response Properties in Cortical Area V1 (2010, background): “The current model thus suggests that it is only the distribution of the source of suppression, rather than its total strength, that changes with temporal frequency and this argues against suggestions that cortex is not a source of the suppression generated by high temporal frequency stimuli (Carandi”
Do We Know What the Early Visual System Does? (2005, background): “The contrast-normalization model has been influential in psychophysical modeling (Watson and Solomon, 1997) as well as in understanding the details of simple-cell (and complex-cell) responses; it is ironic that its proponents now suggest a very different neurophysiological mechanism (Carandini et al”
Dynamics of Suppression in Macaque Primary Visual Cortex (2006, background): “More recently, Carandini and his colleagues (Carandini et al., 2002; Freeman et al., 2002) have proposed that suppression results from the depression of thalamocortical synapses.”
The Operating Point of the Cortex: Neurons as Large Deviation Detectors (2007, background): “…that gain changes are distributed across the early visual pathway, including the retina, the LGN, and cortex (Shapley and Victor, 1979; Smirnakis et al., 1997; Chander and Chichilnisky, 2001; Carandini et al., 2002; Demb, 2002; Freeman et al., 2002; Solomon et al., 2004; Bonin et al., 2006).”
Feed-Forward Segmentation of Figure-Ground and Assignment of Border-Ownership (2010, background): “Intra-cortical surround inhibition, on the other hand is rather slow, tens of milliseconds [33].”
Temporal properties of surround suppression in cat primary visual cortex (2007, background): “Indeed, a feedforward model of cross-orientation suppression based on LGN responses forms the basis of current views of this phenomenon ~Carandini et al., 2002; Freeman et al., 2002; Li et al., 2006; Priebe & Ferster, 2006!.”

(2005, result): “…Kisvarday, & Eysel, 1997; Deangelis et al., 1992; Worgotter & Koch, 1991; Somers, Nelson , & Sur, 1995), although it has also been proposed that thalamocortical inhibition could produce a functionally similar result (Carandini, Heeger, & Senn, 2002; Freeman, Durand, Kiper, & Carandini, 2002).”
Mechanisms underlying cross-orientation suppression in cat visual cortex (2006, background): “In light of these results, it has been proposed that cross-orientation suppression arises from short-term synaptic depression at the thalamocortical synaps”
