Neurons in the visual cortex respond selectively to stimulus orientation and spatial frequency. Changes in response amplitudes of these neurons could be the neurophysiological basis of orientation and spatial frequency discrimination. We have estimated the minimum differences in stimulus orientation and spatial frequency that can produce reliable changes in the responses of individual neurons in cat visual cortex. We compare these values with orientation and spatial frequency discrimination…

Orientation discrimination sensitivity of single units in cat primary visual cortex
The relationship predicts that the coefficient of variation (SD/R) will be smallest near the peak of the tuning curve, indicating that the peak response is most reliable for detecting an orientation but not necessarily the most sensitive to a change in orientation.
Information Tuning of Populations of Neurons in Primary Visual Cortex
A theoretical framework is developed, the information tuning curve, that measures the discrimination power of cells as a function of the orientation difference, δθ, of the two stimuli and finds that narrow orientation tuning is not necessarily optimal for all angular discrimination tasks.
Quantitative study of striate single unit responses in monkeys performing an orientation discrimination task
The results provide for the first time an estimation of the orientation tuning properties of V1 cells during visual orientation discrimination, a property which contribute to the fast and reliable coding of contour orientation.
Contrast-dependent changes in spatial frequency tuning of macaque V1 neurons: effects of a changing receptive field size.
The results indicate that contrast changes in the spatial frequency tuning curves result from spatial reorganization of the receptive field, and a fundamental property of receptive field organization, spatial summation, is not contrast invariant.

Removing stimulus latency from the responses, by time-shifting the individual responses an amount equal to the average latency, significantly reduced the ability to predict stimulus contrast, demonstrating that the response latency is reliable enough, even for a single neuron and a single trial, for it to be used to help determine stimulus contrast.
Response Variability of Neurons in Primary Visual Cortex (V1) of Alert Monkeys
The data show that fixational eye movements cause a large component of response variance in alert monkeys, and the high reliability of neurons in primary visual cortex of alert monkeys is consistent with expectations from conventional biophysical models, and it suggests that activity in a modest number of neurons may suffice to form a perceptual decision.

The results show that the discriminative capacity of V1 neurons does not depend so much on each of the tuning characteristics--bandwidth, response strength, and variability--as on the combination of these factors.
Cortical processing of hyperacuity tasks


Neurophysiological evaluation of the differential response model for orientation and spatial-frequency discrimination.
Using receiver operating characteristic analysis, it is found that two cells from a sample of neurons from the cat's striate cortex could reliably signal orientation differences of 1.84 deg and spatial-frequency differences of 0.073 octave.
The effects of contrast on visual orientation and spatial frequency discrimination: a comparison of single cells and behavior.
Comparison of the effects of contrast on human psychophysical orientation and spatial frequency discrimination thresholds and on the responses of individual neurons in the cat's striate cortex shows that the discrimination of orientation or spatial frequency improves with contrast at low contrasts more than at higher contrasts.
Spatial and temporal contrast sensitivity of neurones in areas 17 and 18 of the cat's visual 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.

The performance of individual neurons in monkey striate cortex has been examined in three spatial-resolution tasks by making microelectrode recordings from single cells in anaesthetized, paralyzed animals and calculations indicate that these cells are poorer at localization than many other cells in the cortex.
Patterns in the discharge of simple and complex visual cortical cells
The activity of visual cortical neurons (area 17) was recorded in anaesthetized cats in response to sinusoidal drifting gratings and it has been found that the invariance property for simple cells is not valid.
Independence of orientation and size in spatial discriminations.
Orientation and spatial frequency are independent dimensions at the discrimination stage of spatial information processing and are as acute when the two gratings had the same spatial frequencies as when they had different spatial frequencies.
Response variability and orientation discrimination of single cells in striate cortex of cat
It is suggested that the same type of intracortical wiring produces orientation selectivity in simple and complex cells, and that the differences in tuning width are mainly due to a larger extension of inhibitory fields in the simple cells.
