Spatial and temporal contrast sensitivity of neurones in areas 17 and 18 of the cat's visual cortex.
TLDR
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.
Spatial summation in the receptive fields of simple cells in the cat's striate cortex.
1. We have examined the responses of simple cells in the cat's atriate cortex to visual patterns that were designed to reveal the extent to which these cells may be considered to sum light‐evoked
Receptive field organization of complex cells in the cat's striate cortex.
TLDR
The subunits of a complex receptive field may, by their spatial properties, determine the spatial selectivities of complex cells, while the nature of the interaction among the subunits may determine these cells' sensitivity and selectivity for moving visual stimuli.
Do We Know What the Early Visual System Does?
TLDR
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.
Amplitude spectra of natural images.
Psychophysical evidence for sustained and transient detectors in human vision
TLDR
The sensitivity to temporally modulated sinusoidal gratings was determined and two thresholds could be distinguished: the contrast at which flicker could be perceived and the Contrast at which the spatial structure became distinct.
The Receptive-Field Organization of Simple Cells in Primary Visual Cortex of Ferrets under Natural Scene Stimulation
TLDR
The responses of simple cells in primary visual cortex to sinusoidal gratings can primarily be predicted from their spatial receptive fields, as mapped using spots or bars, but when these maps are used to predict the actual responses of the cells to natural scenes, they do not find evidence of expansive output nonlinearity and nonlinear influences from outside the classical receptive fields.
On the distinctness of simple and complex cells in the visual cortex of the cat.
TLDR
The behaviour of neurones in cat striate cortex was examined in response to moving sinusoidal gratings and flashed bright and dark lines to find complex cells with distinguishable excitatory and inhibitory regions in their receptive fields showed distinctive behaviour.
