Prefrontal cortex and the generation of oscillatory visual persistence
(Cambridge University Press, 2003)
In this commentary, the formation of ¿pre-iconic¿ visual-prime persistence is described in the context of prime-specific, independent-component activation at prefrontal and posterior EEG-recording sites. Although this ...
Evidence for 40-Hz oscillatory short-term visual memory revealed by human reaction-time measurements
(American Psychological Association, 2000-05)
Four experiments show that presentation of a synchronous premask frame within a 40-Hz, flickering premask matrix primes subsequent detection of a Kanizsa-type square by generation of a 40-Hz prime. Reaction time (RT) priming ...
Structural imbalance and aesthetic preference in domestic chicks
(The International Society for Psychophysics, 2010-10)
In Arnheim¿s (1954/1974) theory of structural balance, an image is more aesthetically pleasing when it demonstrates balance between multiple internal sources of directed perceptual force. Areas of balance and preferred ...
A moment to reflect upon perceptual synchrony
(MIT Press, 2006-10)
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 ...
Electrophysiological correlates of flicker-induced form hallucinations
(The International Society for Psychophysics, 2010-10)
Form hallucinations can be reliably induced using temporally modulated light within a specific frequency range (15-30Hz). The neural substrates of such states have yet to be established with certainty. Brain activity of 5 ...
Temporal structure and inner psychophysics: A glimpse of equilibrium?
(The International Society for Psychophysics, 2010-10)
It has been suggested that the synchronization of spatially distributed neural assemblies at fast frequencies in the range 20 - 80 Hz (the ¿gamma¿ band) is instrumental for binding the separate feature-elements of a figure ...
Synchronous information presented in 40-Hz flicker enhances visual feature binding
(Blackwell, 1998-01)
Recent neurophysiological studies have encouraged speculation that the synchronization of spatially distributed neural assemblies (at around 40 Hz in the neocortex) is responsible for the binding of discrete stimulus ...
Modeling as part of perception: a hypothesis on the function of neural oscillations
(Pabst Science Publishers, 2001)
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 ...
The visual hallucinatory response to flickering polychromatic light.
(The International Society for Psychophysics, 2004)
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 ...
Extended visual simultaneity thresholds in patients with schizophrenia
(Oxford University Press, 2009-07)
Clinical observations suggest that the experience of time phenomenology is disturbed in schizophrenia, possibly originating disorders in dynamic cognitive functions such as language or motor planning. We examined the ...
