Inferring resting-state connectivity patterns from functional magnetic resonance imaging (fMRI) data is a challenging task for any analytical technique. In this paper, we review probabilistic independent component analysis (PICA) approach, optimized the of fMRI data, and discuss role which exploratory technique can take in scientific investigations into structure these effects. We apply PICA to acquired at rest, order characterize spatio-temporal such demonstrate that an effective robust...
Abstract The involvement of the left inferior prefrontal cortex (LIPC) in phonological processing is well established from both lesion-deficit studies with neurological patients and functional neuroimaging normals. Its semantic processing, on other hand, less clear. Although many imaging have demonstrated LIPC activation during tasks, this may be due to implicit processing. This article presents two experiments investigating functions LIPC. Results a magnetic resonance experiment that...
How does the bilingual brain distinguish and control which language is in use? Previous functional imaging experiments have not been able to answer this question because proficient bilinguals activate same regions irrespective of being tested. Here, we reveal that neuronal responses within left caudate are sensitive changes or meaning words. By demonstrating effect populations German-English Japanese-English bilinguals, suggest plays a universal role monitoring controlling use.
It is generally assumed that abstract concepts are linguistically coded, in line with imaging evidence of greater engagement the left perisylvian language network for than concrete words (Binder JR, Desai RH, Graves WW, Conant LL. 2009.

Is the left inferior frontal cortex (LIFC) a single functional region, or can it be subdivided into distinct areas that contribute differently to word processing? Here we used transcranial magnetic stimulation (TMS) investigate anterior and posterior LIFC when meaning sound of words were being processed. Relative no stimulation, TMS selectively increased response latencies participants focused on simultaneously presented (i.e., synonym judgments) but not they pattern homophone judgments). In...
The large-scale sharing of task-based functional neuroimaging data has the potential to allow novel insights into organization mental function in brain, but field lagged behind other areas bioscience development resources. This paper describes OpenFMRI project (accessible online at http://www.openfmri.org), which aims provide community with a resource support open fMRI studies. We describe motivation project, focusing particularly on how this addresses some well-known challenges data....
Category-specific semantic impairments have been explained in terms of preferential damage to different types features (e.g., perceptual vs. functional). This account is compatible with cases which the were result relatively focal lesions, as herpes encephalitis. Recently, however, there reports category-specific associated Alzheimer's disease, more widespread, patchy damage. We present experiments a connectionist model that show how ficategory-specificfl can arise both localized and...

Morphology is the aspect of language concerned with internal structure words, and languages vary in extent to which they rely on morphological structure. Consequently, it not clear whether morphology a basic element linguistic or emerges from systematic regularities between form meaning words. Here, we looked for evidence at neural systems level by using visual masked priming paradigm functional MRI. Form relations were manipulated 2 × design identify reductions blood oxygenation...
Abstract The neural systems sustaining object naming were examined using the activation likelihood estimation (ALE) meta‐analysis approach on results of 16 previously published studies. task in each study required subjects to name pictures objects or animals, but baseline tasks varied. Separate meta‐analyses carried out studies that used: (1) high‐level baselines control for speech processing and visual input; (2) low‐level did not complex processing. two then compared directly, revealing a...
