Drug-resistant focal epilepsy is a major clinical problem and surgery under-used. Better non-invasive techniques for epileptogenic zone localization are needed when MRI shows no lesion or an extensive lesion. The interictal ictal before propagation from the zone. High-density EEG (HDEEG) magnetoencephalography (MEG) offer millisecond-order temporal resolution to address this but co-acquisition challenging, MEG studies rare, long-term prospective lacking, fundamental questions remain. Should...
L-theanine (γ-glutamylethylamide) is an amino acid found primarily in the green tea plant. This study explored effects of L-theanine-based nutrient drink on mood responses to a cognitive stressor. Additional measures included assessment performance and resting state alpha oscillatory activity using magnetoencephalography (MEG). Thirty-four healthy adults aged 18-40 participated this double-blind, placebo-controlled, balanced crossover study. The primary outcome measure, subjective stress...
Abstract Machine learning can be used to define subtypes of psychiatric conditions based on shared biological foundations mental disorders. Here we analyzed cross-sectional brain images from 4,222 individuals with schizophrenia and 7038 healthy subjects pooled across 41 international cohorts the ENIGMA, non-ENIGMA public datasets. Using Subtype Stage Inference (SuStaIn) algorithm, identify two distinct neurostructural subgroups by mapping spatial temporal ‘trajectory’ gray matter change in...
An influential neural model of face perception suggests that the posterior superior temporal sulcus (STS) is sensitive to those aspects faces produce transient visual changes, including facial expression. Other researchers note recognition expression involves multiple sensory modalities and suggest STS also may respond crossmodal signals change transiently. Indeed, many studies audiovisual (AV) speech show involvement in AV integration. Here we examine whether these findings extend emotion....
<title>Abstract</title> Consciousness emerges from complex neural processes, yet its precise neurobiological correlates remain uncertain. Here a space-time-resolved inference-based framework is applied to estimate the neurophysiological variables of whole-cortex model and analyze mechanism global consciousness by way correlation analysis between behavioural variable time-series. Using magnetoencephalography (MEG) data 15 participants under Xenon-induced anesthesia, interconnected mass models...
We used functional imaging of normal subjects to identify the neural substrate for perception voices in external auditory space. This fundamental process can be abnormal psychosis, when that are not true objects (auditory verbal hallucinations) may appear originate The as space depends on filtering by outer ear. Psychoses distort this involve cerebral cortex. Functional magnetic resonance was carried out 12 using an inside-the-scanner simulation 'inside head' and 'outside form typical...
Digital games can be powerful learning environments because they encourage active and participation within “affinity groups” (Gee, 2004). However, the use of in formal educational is not always successful (O’Neil et al., 2005). There a need to update existing theories motivation engagement order take recent game-related developments into account. Understanding links between why people play games, what keeps them engaged this process, learn as result could have significant impact on how value...
Abstract Stop‐signal paradigms operationalize a basic test of goal‐directed behaviour whereby an overarching stop goal that is performed intermittently must be maintained throughout ongoing performance reaction time go task (go goal). Previous studies sustained brain activation during stop‐signal in humans did not observe the dorsolateral prefrontal cortex ( DLPFC ) that, concert with parietal cortex, known to subserve maintenance. Here we explored hypothesis and network has key role...
Speech and emotion perception are dynamic processes in which it may be optimal to integrate synchronous signals emitted from different sources. Studies of audio-visual (AV) neutrally expressed speech demonstrate supra-additive (i.e., where AV>[unimodal auditory+unimodal visual]) responses left STS crossmodal stimuli. However, emotions often conveyed simultaneously with speech; through the voice form prosody face facial expression. Previous studies AV nonverbal integration showed a role for...
Altered brain functional connectivity has been observed in conditions such as schizophrenia, dementia and depression may represent a target for treatment. Transcutaneous vagus nerve stimulation (tVNS) is form of non-invasive that increasingly used the treatment variety health conditions. We previously combined tVNS with magnetoencephalography (MEG) various frequencies affected different areas healthy individuals. further investigated whether had an effect on focus regions associated mood....
Predictive coding theories of perception highlight the importance constantly updated internal models world to predict future sensory inputs. Importantly, such suggest that prediction-error signalling should be specific violation predictions concerning distinct attributes same stimulus. To interrogate this as yet untested prediction, we focused on two different aspects face (identity and orientation) investigated whether cortical regions which process particular stimulus also signal...
Objective.Transcutaneous vagus nerve stimulation (tVNS) is a form of non-invasive brain that delivers sequence electrical pulses to the auricular branch and used increasingly in treatment number health conditions such as epilepsy depression. Recent research has focused on efficacy tVNS treat different medical conditions, but there little conclusive evidence concerning optimal parameters. There are relatively few studies have combined with neuroimaging modality, none attempted simultaneous...
Age-related cognitive decline (ARCD) is of major societal concern in an ageing population, with the development dietary supplements providing a promising avenue for amelioration associated deficits. Despite initial interest use phospholipids (PLs) ARCD, recent years there has been hiatus such research. Because safety concerns regarding PLs derived from bovine cortex, and equivocal efficacy soybean-derived PLs, important need new PL alternatives. Phospholipids milk proteins represent one...
While advances in the field of functional magnetic resonance imaging (fMRI) provide new opportunities to study brain networks underlying experience hallucinations psychosis, there are methodological challenges unique symptom-capture studies.
Modulation perception has typically been characterized by measuring detection thresholds for sinusoidally amplitude-modulated (SAM) signals. This study uses multicomponent modulations. “Second-order” temporal modulation transfer functions (TMTFs) measure a sinusoidal of the waveform SAM signal [Lorenzi et al., J. Acoust. Soc. Am. 110, 1030–2038 (2001)]. The therefore acts as “carrier” stimulus frequency fm, and signal’s depth (at rate fm′) generates two additional components in spectrum at...
Abstract In the last few years, digital games have become increasingly popular with both 'hardcore' and 'casual' audiences. At same time, it has been argued that can be powerful learning environments, since they are seen to encourage active critical through participation in affinity groups semiotic domains but there is a need for further empirical evidence explore how this occurs prevalent actually is. addition effectiveness of within education indicates mixed results, though suggested may...
