TL;DR
Using the activity-dependent 2-[14C]deoxy-D-glucose technique, a columnar organization of spatial frequency--specific sensitivity in striate cortex is demonstrated and Cats viewing patterns containing a single spatial frequency presented at all orientations show columns of increased deoxyglucOSE uptake extending through all cortical layers.
Abstract
Using the activity-dependent 2-[14C]deoxy-D-glucose technique, we have demonstrated a columnar organization of spatial frequency--specific sensitivity in striate cortex. Cats viewing patterns containing a single spatial frequency presented at all orientations show columns of increased deoxyglucose uptake extending through all cortical layers. A control stimulus containing all spatial frequencies presented at all orientations produces no columnar density differences within the striate cortex.

The method can be applied to most laboratory animals in the conscious state and is based on the use of 2‐deoxy‐D‐[14C]glucose as a tracer for the exchange of glucose between plasma and brain and its phosphorylation by hexokinase in the tissues.

In most respects the above description fits the newborn monkey just as well as the adult, suggesting that area 17 is largely genetically programmed.

It was found that an occipital evoked potential can be elicited in the human by moving a grating pattern without changing the mean light flux entering the eye.
Brain ResearchChanges in the visual system of monocularly sutured or enucleated cats demonstrable with cytochrome oxidase histochemistry
1,867 Citations1979Margaret T.T. Wong‐Riley
The results indicated that the deprivation caused by monocular suture produced a decrease in the cytochrome oxidase staining of the binocular segment of the deprived geniculate laminae of kittens, leading to a significant decreases in the level of oxidative enzyme activity one to several synapses away.
The Journal of PhysiologyThe representation of the visual field on the cerebral cortex in monkeys
1,158 Citations1961P. M. Daniel, D. Whitteridge
On the basis of his extensive and elegant anatomical investigations on the visual cortex, Poliak (1932) suggested that a mathematical projection of the retina on the cerebral cortex must exist and this work has made such a surface, folded it and compared it with the calcarine cortex of the monkey.

Questions were approached by making several deep, closely spaced, parallel micro-electrode penetrations, placing electrolytic lesions at every shift in receptive-field orientation, and by making many short penetrations in a small cortical area, noting the axis orientation of cells lying in the upper one or two layers of cortex.

A single representation of the cat's entire visual field corresponds closely to the cytoarchitectonically defined area 17, which is related to the locations of the corresponding recording sites in the cortex.

It is concluded that areas 17 and 18 act in parallel to process different aspects of the visual information relayed from the retina via the lateral geniculate complex.
Vision ResearchThe visual cortex as a spatial frequency analyser
631 Citations1973Lamberto Maffei, Adriana Fiorentini
Unitary responses to sinusoidal gratings either moving or alternating in phase have been investigated in the optic tract, lateral geniculate body and visual cortex of the cat as a function of the spatial frequency, position of the grating with respect to the cell receptive field and grating contrast.

In the macaque monkey striate (primary visual) cortex, the grouping of cells into ocular dominance and orientation columns leads to the prediction of highly specific spatial patterns of cellular activity in response to stimulation by lines through one or both eyes.

279 Citations1970Edmund T. Rolls, Alan Cowey
The results of this study, in which acuity and topography of the visual system are compared in two species of monkey, are consistent with the view that both retinal topography, and the cortical magnification of thevisual field, are closely related to visual acuity.

The orientation tuning, spatial‐frequency tuning and responsiveness of cells to a plaid pattern were found to be predictable from the pattern's two‐dimensional Fourier spectrum, and both simple and complex striate cortex cells can be characterized as two-dimensional spatial‐ frequencies filters.
Vision ResearchInteractions between spatial frequency channels
156 Citations1978D.J. Tolhurst, L.P. Barfield
The sensitivities for sinusoidal gratings of various spatial frequencies were determined by a two-alternative forced-choice technique and when the testing frequency was close to the masking or adapting frequency, threshold was elevated, but when the frequencies differed by 1–2 octaves, the threshold was lowered (sensitivity was increased).

The functional architecture of this cortical area of area 17 of the cat is examined with respect to the spatial frequency of the visual stimulus (sinusoidal gratings) at which each neuron is most sensitive.

The architectural pattern of glucose utilization in the cortex during focal seizures is discussed with reference to corticocortical, commissural, and corticothalamic circuits that have been identified by others in anatomical studies.

All of the cells recorded from the visual cortex of monkeys and cats were considerably more selective along the dimension of spatial frequency than along thedimension of bar width.
