How does neuronal activity bring about the interpretation of visual space in terms of objects or complex perceptual events? If they group, simple visual features can bring about the integration of spikes from neurons ...

Recent advances in auditory research suggest that gamma-band synchronization of frequency-specific cortical loci could be responsible for the integration of pure tones (harmonics) into harmonic complex tones. Thus far, ...

The benzodiazepine, Lorazepam enhances the efficiency of inhibitory GABA-A synapses in the cortex, which stabilize postsynaptic, excitatory activity by synchronizing their own discharges at around 40 Hz. Lorazepam treatment ...

Using a primed figure-detection task we were able to reveal the existence of two distinct groups of dyslexics. One group is characterized by a significant impairment of visual integration-segmentation processes, resulting ...

Fechner described the phenomenon of inducing illusory colors by means of rotating blackand- white disks. The induced spectral illusions were later termed "Fechner's colors". Similar color perceptions can be induced by ...

We examined the effects of negative delays on the perception of causality using a variation of the paradigm originated by Michotte (1954) and as an extension to similar work conducted by Kanizsa and Vicario (1968). In our ...

We argue that the effectiveness of synchronization of oscillatory neural activities coding simple features, as it relates to perceptual organization, may originate in the temporal characteristics of resonance that develops ...

Our understanding of human visual perception generally rests on the assumption that conscious visual states represent, in some qualitative fashion, a complex interaction between spatially structured variations in the ambient ...

Search rates are often used as a measure of search efficiency. Horowitz & Wolfe employed this measure to compare static and dynamic visual search (Horowitz & Wolfe, 1998). Based on identical search rates, they argued that ...
