Journal ArticleDOI
The two-dimensional spatial structure of simple receptive fields in cat striate cortex
J. P. Jones,L. A. Palmer +1 more
TL;DR: A reverse correlation method is developed that allows quantitative determination of visual receptive-field structure in two spatial dimensions and it is demonstrated that thereverse correlation method yields results with several desirable properties, including convergence and reproducibility independent of modest changes in stimulus parameters.

Do we know what the early visual system does
Matteo Carandini,Jonathan B. Demb,Valerio Mante,David J. Tolhurst,Yang Dan,Bruno A. Olshausen,Jack L. Gallant,Nicole C. Rust +7 more
TL;DR: Research is progressing with the goals of defining a single “standard model” for each stage of the visual pathway and testing the predictive power of these models on the responses to movies of natural scenes, which would be an invaluable guide for understanding the underlying biophysical and anatomical mechanisms and relating neural responses to visual perception.

Classifying simple and complex cells on the basis of response modulation.
Bernt C. Skottun,Russell L. De Valois,David H. Grosof,J. Anthony Movshon,Duane G. Albrecht,A. B. Bonds +5 more
TL;DR: Evidence is reviewed which indicates that this simple, objective classification criterion based on the form of the response to drifting sinusoidal gratings divides neurons of the striate cortex in both cats and monkeys into two groups that correspond closely to the classically-described simple and complex classes.

Mechanisms of contour perception in monkey visual cortex. II. Contours bridging gaps
E. Peterhans,R. von der Heydt +1 more
TL;DR: The contour responses in V2, the nonadditivity, and the effect of closure can be explained by the previously proposed model (Peterhans et al., 1986), assuming that the corners excite end-stopped fields orthogonal to the contours whose signals are pooled in the contour neurons.
Journal ArticleDOI
Logical/linear operators for image curves
Lee Iverson,Steven W. Zucker +1 more
TL;DR: A family of logical/linear (L/L) operators appropriate for measuring the low-order differential structure of image curves is developed, derived by decomposing a linear model into logical components to ensure that certain structural preconditions for the existence of an image curve are upheld.

Receptive fields, binocular interaction and functional architecture in the cat's visual cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: This method is used to examine receptive fields of a more complex type and to make additional observations on binocular interaction and this approach is necessary in order to understand the behaviour of individual cells, but it fails to deal with the problem of the relationship of one cell to its neighbours.
Journal ArticleDOI
Theory of Edge Detection
David Marr,Ellen C. Hildreth +1 more
TL;DR: The theory of edge detection explains several basic psychophysical findings, and the operation of forming oriented zero-crossing segments from the output of centre-surround ∇2G filters acting on the image forms the basis for a physiological model of simple cells.
Journal ArticleDOI
Receptive fields of single neurones in the cat's striate cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: The present investigation, made in acute preparations, includes a study of receptive fields of cells in the cat's striate cortex, which resembled retinal ganglion-cell receptive fields, but the shape and arrangement of excitatory and inhibitory areas differed strikingly from the concentric pattern found in retinalganglion cells.
Journal ArticleDOI
What the Frog's Eye Tells the Frog's Brain
TL;DR: The results show that for the most part within that area of the optic nerve of a frog, it is not the light intensity itself but rather the pattern of local variation of intensity that is the exciting factor.
Journal ArticleDOI
Single units and sensation: a neuron doctrine for perceptual psychology?
TL;DR: To understand nervous function one needs to look at interactions at a cellular level, rather than either a more macroscopic or microscopic level, because behaviour depends upon the organized pattern of these intercellular interactions.
