An investigation of cognitive dysmetria in developmental dyslexia
(Pion Ltd, 2006)
An alternative to theories positing visual or phonological deficits, the 'cognitive dysmetria' hypothesis proposes the aetiology of dyslexia to take the form of a general functional coordination deficit or cognitive ...
Low-level temporal coding impairments in psychosis: Preliminary findings and recommendations for further studies.
(American Psychological Association, 2011)
We investigated whether difficulties with temporal event-coding, previously reported in patients with schizophrenia, are already present during first-episode psychosis (FEP). In this experiment, the subjective judgements ...
Prefrontal cortex and the generation of oscillatory visual persistence
(Cambridge University Press, 2003-12-01)
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 ...
Atypical behavioural effects of lorazepam: Clues to the design of novel therapies?
(Elsevier, 2010-04)
Aside from their pharmacokinetic properties, e.g. their speed of action and the duration of residual effects, benzodiazepines are still considered as equivalent in terms of their effects on cognition. Here we review evidence ...
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. ...
Process timing and its relation to the coding of tonal harmony.
(American Psychological Association, 2010)
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, evidence ...
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 ...
