TL;DR
In predictive coding, only unexpected input features are signaled to the next stage of processing, and Rao and Ballard use this approach to model extra–classical receptive field effects.

Nature NeurosciencePredictive coding in the visual cortex: a functional interpretation of some extra-classical receptive-field effects
5,736 Citations1999Rajesh P. N. Rao, Dana H. Ballard
Results suggest that rather than being exclusively feedforward phenomena, nonclassical surround effects in the visual cortex may also result from cortico-cortical feedback as a consequence of the visual system using an efficient hierarchical strategy for encoding natural images.

NatureA cortical representation of the local visual environment
3,112 Citations1998Russell A. Epstein, Nancy Kanwisher
Evidence is presented that a particular area within human parahippocampal cortex is involved in a critical component of navigation: perceiving the local visual environment, and it is proposed that the PPA represents places by encoding the geometry of the local environment.

This work presents simplified models of individual neurons, and unconventional coupling, of action-potential generation and phase space analysis of neuronal excitability in response to the Hodgkin-Huxley model.

The results suggest that IT neurons can develop a complex receptive field organization as a consequence of extensive training in the discrimination and recognition of objects, and support the idea that a population of neurons tuned to a different object aspect, and each showing a certain degree of invariance to image transformations--may encode at least some types of complex three-dimensional objects.

It is suggested that the connections between these cortical areas of the macaque monkey visual system never form strong, directed loops, and it is predicted that certain types of connections will not be found.

Neural ComputationDynamic Model of Visual Recognition Predicts Neural Response Properties in the Visual Cortex
302 Citations1997Rajesh P. N. Rao, Dana H. Ballard
A hierarchical network model of visual recognition that explains experimental observations regarding neural responses in both free viewing and fixating conditions by using a form of the extended Kalman filter as given by the minimum description length (MDL) principle is described.
Image and Vision ComputingNeurophysiology of shape processing
213 Citations1993David I. Perrett, Mike W. Oram
This scheme provides a route to 3D object recognition through 2D shape description and reduces the problem of perceptual invariance to a series of independent analyses with an associative link established between the outputs.
Die NaturwissenschaftenA neuronal circuitry for relative movement discrimination by the visual system of the fly
60 Citations1981Tomaso Poggio, W. Reichardt +1 more
The main features of the circuitry are: binocular cells summate elementary movement detectors over a large visual field and inhibit each one of them; inhibition is of the shunting type, with an inhibitory equilibrium potential very near the resting potential.
