Several behavioral studies have shown that developmental dyslexics do poorly in tests
requiring rapid visual processing. In primates fast, low-contrast visual information is carried …

Our visual system can process information at both conscious and unconscious levels.
Understanding the factors that control whether a stimulus reaches our awareness, and the …

A neural network model that controls behavioral timing is described and simulated. This
model, called the Spectral Timing Model, controls a type of timing whereby an animal or …

We used fast, pseudorandom temporal sequences of preferred and antipreferred stimuli to
drive neuronal firing rates rapidly between minimal and maximal across the visual system …

What brain mechanisms underlie autism, and how do they give rise to autistic behavioral
symptoms? This article describes a neural model, called the Imbalanced Spectrally Timed …

Proposes theoretical integration of a mechanistic, causal analysis and behavioral analysis of
visual masking phenomena. It is shown that several known aspects of visual masking are …

Coarse-to-fine theories of vision propose that the coarse information carried by the low
spatial frequencies (LSF) of visual input guides the integration of finer, high spatial …

Pattern reversal visual evoked potentials were recorded from 125 visually normal adults
between 10 and 80 years of age. Two check sizes, 12 and 48 min, were used. The results …

VEPs were recorded with three different spatial frequencies of stimulation in patients
affected by idiopathic Parkinsonism and by Parkinsonian syndromes. The detection of VEP …
