There are some key principles of gestalt systems like emergence, reification, multistability and invariance. Do any neuronal models exist to explain these properties?
I agree, lateral inhibition is good for contrast strengthening or edge detection but there are many more effects in Gestalt psychology like proximity, similarity, closure, symmetry and many more. See: http://en.wikipedia.org/wiki/Gestalt_psychology
Pieter R. Roelfsema addresses many of these issues in "Cortical Algorithms for
Perceptual Grouping" in Annual Review of Neuroscience. 2006. 29:203–27.

Some of this research deals with proximity, similarity, closure etc., in terms of neural networks in early visual cortex, especially V1 and V2. Hebb's previous research on neurons that fire/wire together go together has been implicated in Gestalt grouping as well as the long range and short range neural interconnections in early visual cortex.
On a more molar level, Feil et al. (2010) describe the exclusivity of sober and intoxicated networks in addiction.

The utility of neuronal models applied to Gestalt psychology can be most readily apparent in study of visual perception. In particular, Ecological psychology models that place the human actor within his environmental niche - addressing all that implies, both experientially and behaviorally - offer a natural context by which to theorize how a rich visual Gestalt can guide the human actor. J.J. Gibson was particularly helpful in providing a theoretical vision of this human ecological psychological system, inferring that it was the information embodied in the visual environmental array - and not sensations tied to neuronal functioning - being used by the human to guide behavior.
In parallel, the work of Karl Pribram on neural networks led to many similar conclusions, albeit from the biological psychology perspective. His contributions to understanding neural function spanned the vast expanse of mental and behavioral function, providing much insight to brain function from micro to macro levels. His late work described neural functioning from the network perspective, again highlighting that the information embodied within the dendritic webs, and the inherent algorythmic activity of those webs, provided essentially holographic storage of information to be used by the human actor.
I would add that the tendancy to address Gestalt phenomena as tidbits of perception and illusions that can be made to play visual tricks, using localized neuronal eleectrochemical interactions, are likely to miss the main point (found by Lashley back in the fifties). It's not the localized cortical activity (the engram) by which perception can be explained - it's the distributed interplay of afferent and efferent information that resides within the cortical network.
