The development of the Brain Imaging Data Structure (BIDS; Gorgolewski et al., 2016) gave neuroscientific community a standard to organize and share data. BIDS prescribes file naming conventions folder structure store data in set already existing formats. Next rules about organization itself, provides standardized templates associated metadata form Javascript Object Notation (JSON) tab separated value (TSV) files. It thus facilitates sharing, eases querying, enables automatic analysis...
Abstract The functional organization of speech sound processing in the human brain and its unfolding over time are still not well understood. While N100/N100m is a comparatively well‐studied, quite late, component auditory evoked field elicited by speech, earlier processes such as those reflected P50m remain to be resolved. Using magnetoencephalography, present study follows up on previous reports N100m‐centred spatiotemporal encoding phonological features coarticulatory cortex during...
In casual speech, phonemic segments often assimilate such that they adopt features from adjacent segments, a typical feature being their place of articulation within the vocal tract (e.g., labial, coronal, velar). Place assimilation coronal /n/ to labial /m/: rainbow→*raimbow) alters surface form words. Listeners' ability perceptually compensate for changes seems depend on context, whether segment /b/ in “rainbow”) invites particular change. Also, some assimilations occur frequently...
We investigated the oscillatory neural correlates of auditory lexical processing in healthy adults. Synthetic aperture magnetometry was used to characterize timing event-related desynchronization (ERD)/event-related synchronization (ERS) superior temporal gyri following low-frequency and high-frequency words contrast nonwords. ERS ERD responses were found with both word nonword stimuli. Analysis power revealed significantly elevated θ-α range (6-14 Hz) response compared nonwords (left...
Word learning is a significant milestone in language acquisition. The second year of life marks period dramatic advances infants' expressive and receptive word-processing abilities. Studies show that adulthood, processing left-hemisphere dominant. However, adults activate right-hemisphere brain functions. In infancy, acquisition first involves recruitment bilateral networks, strong dominance emerges by the third year. current study we focus on 14-month-old infants earliest stages word using...
Magnetoencephalography (MEG) is an excellent non-invasive tool to study the brain. However, measurements often suffer from contribution of external interference, including noise sensors. Suppression data critical for accurate representation brain signals. Due MEG's limited spatial resolution and superior temporal resolution, suppression methods that operate in domain can be favorable.We examined independent joint effects two projection algorithms MEG measurements: One commonly used algorithm...
Magnetoencephalography was used in a passive repetition priming paradigm. Words two frequency bins (high/low) were presented to the participants auditorily. Participants' brain responses these stimuli analyzed using synthetic aperture magnetometry. The main finding of this study is that single-word low-frequency word pairs significantly attenuated post-second event-related desynchronization θ–α (5–15 Hz) bands, at 200–600 ms stimulus onset. Peak significance between repeated high and low...
Children show remarkable progress in word learning the second year of life. This language growth coincides with vocabulary spurt and development domain-general cognition, e.g., attention that facilitates perceptual processing. Evidence suggests depends on increasing processing efficiency underlying neuronal specialization. We used magnetoencephalography (MEG) to characterize neural activity following familiar unfamiliar words 14-month-old infants related measures prospective growth. MEG...
Abstract Skilled reading requires years of practice associating visual symbols with speech sounds. Over the course learning process, this association becomes effortless and automatic. Here we test whether automatic activation spoken-language circuits in response to words is a hallmark skilled reading. Magnetoencephalography was used measure word-selective responses under multiple cognitive tasks (N = 42, 7-12 age). Even when attention drawn away from by performing an attention-demanding...
Infants are sensitive to the distributional characteristics of speech they hear, and perception can be altered by properties language input. listening languages with distinct show at age 6 months based on learning from ambient Perception also in laboratory manipulating a 2-min exposure. However, brain mechanisms underlying this not well understood. Here we used MEG explore neural processes involved on-line learning. We examined responses ambiguous sounds that straddle /ba-wa/ continuum. were...
