Electrophysiological correlates of flicker-induced color hallucinations
(Elsevier, 2009-03)
In a recent study, Becker and Elliott [Becker, C., & Elliott, M. A. (2006). Flicker induced color and form: Interdependencies and relation to stimulation frequency and phase. Consciousness & Cognition, 15(1), 175-196] ...
Visual perception in a snapshot
(Springer, 2006-04-14)
To study visual perception in its sub-second scale of
time continues to be timely: we have more unsolved
puzzles than bits of a firm undisputable knowledge
about how our perceptions are created in a snapshot of
time. ...
Enhanced GABA-A inhibition enhances synchrony coding in human perception
(Lippincott Williams & Wilkins, 2000-10-20)
The benzodiazepine, lorazepam enhances the efficiency of local, inhibitory GABAA synapses in the cortex, which stabilize postsynaptic, excitatory activity by synchronizing their own discharges at around 40 Hz. Treatment ...
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 ...
Flicker-induced color and form: Interdependencies and relation to stimulation frequency and phase
(Elsevier, 2006-03)
Our understanding of human visual perception generally rests on the assumption that conscious visual states represent the interaction of spatial structures in the environment and our nervous system. This assumption is ...
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 ...
Process timing and its relation to the perception of tonal harmony
(Editora Legis Summa Ltda, 2002)
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, ...
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 ...
