Orientation characteristics of a mechanism in the human visual system sensitive to cyclopean form
Development of the Spatial Organization and Dynamics of Lateral Interactions in the Human Visual System
TLDR
Three forms of nonlinear interaction in developing human infants and adults have differences in sensitivity to flanker orientation and position and differential growth trends, indicating that they are generated by different mechanisms.
Orientation tuning in the visual cortex of 3-month-old human infants
The comparability of rat and human visual-evoked potentials
Normalization Models Applied to Orientation Masking in the Human Infant
TLDR
Results are consistent with the existence of oriented filters early in life the responses of which are normalized immaturely until ∼5 months of age, within the context of a normalization model of pattern masking.
Differentiation of VEP intermodulation and second harmonic components by dichoptic, monocular, and binocular stimulation.
TLDR
It is concluded that 2Fs and IMCs are associated with different neural substrates and results are consistent with a two pathway model with one pathway having a nonlinear filter prior to binocular combination, the other pathway having the nonlinearity following binocular linear summation.
Dynamics of Normalization Underlying Masking in Human Visual Cortex
TLDR
The neural mechanisms of masking in humans are studied using source-imaged steady state visual evoked potentials and frequency-domain analysis over a wide range of relative stimulus strengths of test and mask stimuli to suggest that contrast normalization accomplishes multiple functional goals.

TLDR
An ultra-high resolution technique for recording evoked potentials (EPs) that are thousands of times smaller than the total EEG power is described and a theoretical method for calculating the amplitudes and phases of these various cross-modulation components for different arrangements of model neurons is developed.
Two-frequency analysis of interactions elicited by Vernier stimuli
TLDR
For Vernier stimuli devoid of motion, VEP signatures of interaction are readily detected but are not specific to hyperacuity displacements, and the distribution of interactions across harmonic orders is consistent with local rectification preceding the spatial interactions.

TLDR
This book is a critical survey of endeavours to use these electrical responses to sensory stimulation (called evoked potentials) as tools in attempts to discover the ways in which the brain first processes incoming sensory information and then forms internal representations of features of the external world.
