Local contrast in natural images: normalisation and coding efficiency.
Brady N, Field DJ. Brady N, et al. Among authors: Field DJ. Perception. 2000;29(9):1041-55. doi: 10.1068/p2996. Perception. 2000. PMID: 11144818
While restricted in space, the normalisation pool is broadly tuned for spatial frequency and orientation, so that a cell's response is adapted by stimuli which fall outside its 'classical' receptive field. ...

Selectivity, hyperselectivity, and the tuning of V1 neurons.
Vilankar KP, Field DJ. Vilankar KP, et al. Among authors: Field DJ. J Vis. 2017 Aug 1;17(9):9. doi: 10.1167/17.9.9. J Vis. 2017. PMID: 28813565 Review.
If a neuron is linear, then this stimulus can be determined by measuring the response to an orthonormal basis set (the receptive field). ...We demonstrate that this curvature produces a systematic misestimation of the optimal stimulus when the neuron's receptive field is measured with spots or gratings. ...

Conjectures regarding the nonlinear geometry of visual neurons.
Golden JR, Vilankar KP, Wu MC, Field DJ. Golden JR, et al. Among authors: Field DJ. Vision Res. 2016 Mar;120:74-92. doi: 10.1016/j.visres.2015.10.015. Epub 2016 Feb 24. Vision Res. 2016. PMID: 26902730
The family of spatial non-linearities have included interactions that occur both within and outside of the classical receptive field. ...

Can the theory of "whitening" explain the center-surround properties of retinal ganglion cell receptive fields?
Graham DJ, Chandler DM, Field DJ. Graham DJ, et al. Among authors: Field DJ. Vision Res. 2006 Sep;46(18):2901-13. doi: 10.1016/j.visres.2006.03.008. Epub 2006 Jun 16. Vision Res. 2006. PMID: 16782164 Free PMC article.
The proposed goal of this model is to allow neurons with different receptive field sizes to produce the same average response to natural scenes. ...However, using a simulation, both models are shown to be insufficient to explain the center-surround receptive field organization of ganglion cells. ...
