It is generally agreed upon that size invariance and the absence of spurious resolution are two requirements that characterize well behaved spatial samping in visual systems. We show that these properties taken together constrain the structure of receptive fields to a very large degree.

Anæsthesia and Receptive Fields
Nature, 1965Hubel and Wiesel1,2 have described the responses of cells in the cat's visual cortex to precise stimulation of the retina. They say: “A comparison of visual responses in the anaesthetized animal with those in the unansesthetized unrestrained preparation1 shows that the main differences lie in the frequency and firing patterns of maintained activity and

The receptive fields of the retina
Vision Research, 1965Abstract On the basis of psychophysiological and electrophysiological experiments, in which the role of the receptive fields of the retina in light sensitivity, adaptation, contrast, visual acuity, flicker fusion frequency and regulation of eye movements have been investigated, this hypothesis is put forward: according to which the receptive field is

Receptive Field Organization of the S-Potential
Science, 1968The receptive fields of S-potentials have been studied in carp retinas. The relationship between the stimulus intensity and area of stimulation was examined for each component of three different types of S-potential. It appears that for each component there is full summation over a large portion of the retina, a type of organization different from that

Receptive Fields of Auditory Neurons in the Owl [PDF]
Science, 1977 The influence of sound location on the responses of auditory neurons in the forebrain of the owl ( Tyto alba ) was studied directly by using a remotely controlled, movable sound source under free-field, anechoic conditions.

The receptive fields of Daphnia ommatidia [PDF]
Journal of Experimental Biology, 1976 ABSTRACT The focal length and positions of the principal planes of an isolated Daphnia lens were determined, and the refractive index of the rhabdom was measured. The lens can form an image, but this always lies well behind the rhabdom. This was confirmed by direct observation of images inside a clear-eye mutant Daphnia eye.

Visual receptive field organization
Current Opinion in Neurobiology, 2005Increasingly systematic approaches to quantifying receptive fields in primary visual cortex, combined with inspired ideas about functional circuitry, non-linearities, and visual stimuli, are bringing new interest to classical problems. This includes the distinction and hierarchy between simple and complex cells, the mechanisms underlying the receptive ...

N4: computing with neural receptive fields [PDF]
Neurocomputing, 2003 Abstract In this study, we introduce a new neural architecture called N4 that is based on a collection of local receptive fields realized in the form of referential neural networks. While the network exhibits some similarities to other structures of modular neural networks (such as expert networks), it comes with a number of unique features ...

Clustering of receptive fields in Autoencoders
2016 International Joint Conference on Neural Networks (IJCNN), 2016In this paper, we demonstrate new techniques for data representation in the context of deep learning using agglomerative clustering. The results from previous work show that a good number of encoding and decoding filters of layered autoencoders are duplicative thereby enforcing two or more processing filters to extract the same features due to ...

Time evolution of receptive fields
1996 Australian New Zealand Conference on Intelligent Information Systems. Proceedings. ANZIIS 96, 2002A hierarchical model of the early visual system is presented. This model consists of three retinotopically connected layers. Each layer is composed of a one dimensional array of processing units or neurons. The principle feature of this model is that neighbouring neurons exert mutually inhibitory interactions only.
