Effects of TMS on different stages of motor and non-motor verb processing in the primary motor cortex
- PLoS ONE 4:e4508. doi: 10.1371/journal.pone.0004508 Pascual-Leone
, 2009
"... The embodied cognition hypothesis suggests that motor and premotor areas are automatically and necessarily involved in understanding action language, as word conceptual representations are embodied. This transcranial magnetic stimulation (TMS) study explores the role of the left primary motor cortex ..."

-state activated equilibrium on the length of the inter-stimulus interval (ISI), defined as the duration of the resting period between successive stimuli. shows decreased magnitude for stimuli lasting a few seconds. Here, we investigate what effect, if any, the post-stimulus under-shoot has on the kinetics of BOLD
Dynamics of a Recurrent Network of Spiking Neurons Before and Following Learning
, 1998
"... Extensive simulations of large recurrent networks of integrate-and-fire excitatory and inhibitory neurons in realistic cortical conditions (before and after Hebbian unsupervised learning of uncorrelated stimuli) exhibit a rich phenomenology of stochastic neural spike dynamics, and in particular, coe ..."

, coexistence between two types of stable states: spontaneous activity, upon stimulation by an unlearned stimulus; and `working memory' states strongly correlated with learned stimuli. Firing rates have very wide distributions, due to the variability in the connectivity from neuron to neuron. ISI
Neuromagnetic evidence for the timing of lexical activation: an MEG component sensitive to phonotactic probability but not to neighborhood density
"... Evidence from electrophysiological measures such as ERPs (event-related potentials) and MEG (magnetoencephalography) suggest that the first evoked brain response component sensitive to stimulus properties affecting reaction times in word recognition tasks occurs at 300-400 ms. The present study used ..."

used the stimulus manipulation of Vitevich and Luce (1999) to investigate whether the M350, an MEG response component peaking at 300400 ms, reflects lexical or post-lexical processing. Stimuli were simultaneously varied in phonotactic probability, which facilitates lexical activation
Vowel categorization induces departure of M100 latency from acoustic prediction.
- Neuroreport,
, 2004
"... MEG studies have shown that the timing (latency) of the evoked response that peaks B100 ms post-stimulus onset (M100) decreases as frequency increases for sinusoidal tones. We investigated M100 latency using a continuum of synthesized vowel stimuli in which the dominant formant frequency increases ..."

The role of friends' appearance and behavior on evaluations of individuals on Facebook: Are we known by the company we keep?.
- Human Communication Research,

See What I’m Saying? Expertise and Verbalisation in Perception and Imagery of Complex Scenes
- Cognitive Computation
, 2011
"... Abstract How does describing a previously viewed picture affect our memory for it? Does verbalisation affect our eye movements even when the picture has disappeared? When viewing a photograph, the sequences of eye movements we make (‘scanpaths’) are influenced by both bottom-up visual saliency and t ..."

Recognition accuracy was increased by post-stimulus verbalisation, and specialists demonstrated an advantage for stimuli that contained domain-relevant information. Saliency influenced both verbal feedback
Transient adaptation and sensitization in the retina of Necturus
- J. Gen. Physiol
, 1980
"... ABSTRACT Responses to repetitive stimulation were monitored at several retinal levels in the eyecup of the mudpuppy Necturus maculosus. When alternating sequences of low-intensity small and large spots were presented, two effects were found, which could be localized to the proximal retina: (a) respo ..."

Abnormal activation of temporoparietal language areas during phonetic analysis in children with dyslexia
- Neuropsychology
, 2003
"... Event-related magnetic fields were recorded using magnetoencephalography in children with (n 12) and without (n 11) dyslexia while they discriminated between pairs of syllables from a voice onset time series (/ga/–/ka/). Nonimpaired readers exhibited left-hemisphere predominance of activity after ..."

Increased relative activation in right temporoparietal areas was correlated with reduced performance on phonological processing
Antiapoptotic function of RNA-binding protein HuR effected through prothymosin a
