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.

Normalization Models Applied to Orientation Masking in the Human Infant
- Psychology, BiologyThe Journal of Neuroscience
- 2001
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.

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
- Biology, PsychologyThe Journal of Neuroscience
- 2012
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.
Objective Investigation of Visual Function Using a Nondestructive Zoom-FFT Technique for Evoked Potential Analysis
- BiologyCanadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques
- 1989
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
- Psychology, PhysicsVisual Neuroscience
- 2000
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.

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.
