Auditory Processing Disorder International Research. Abnormal auditory and language pathways in children with 16p11.2 deletion. Highlights We examined auditory and language white matter tracts in children with the 16p11.2 BP4–BP5 deletion.
Diffusivity was enhanced in auditory radiation and arcuate fasciculus. Arcuate fasciculus microstructure was correlated with language ability in deletion carriers. A Behavioral Framework to Guide Research on Central Auditory Development and Plasticity. Altered Low-Gamma Sampling in Auditory Cortex Accounts for the Three Main Facets of Dyslexia. Figure 1 Stimulus' Waveform and Spectrogram (A) Waveform of the stimulus used to elicit auditory steady-state responses.
The stimulus is a 5.4 s amplitude modulated (AM) noise with AM linearly increasing from 10 to 80 Hz. (B) Spectrogram of the stimulus. A review and synthesis of the first 20years of PET and fMRI studies of heard speech, spoken language and reading. Open Access Abstract The anatomy of language has been investigated with PET or fMRI for more than 20 years.
Here I attempt to provide an overview of the brain areas associated with heard speech, speech production and reading. The conclusions of many hundreds of studies were considered, grouped according to the type of processing, and reported in the order that they were published. Many findings have been replicated time and time again leading to some consistent and undisputable conclusions. Auditory and visual stream segregation in children and adults: An assessment of the amodality assumption of the ‘sluggish attentional shifting’ theory of dyslexia.

Auditory attention in childhood and adolescence: An event-related potential study of spatial selective attention to one of two simultaneous stories. Open Access Highlights We measured auditory ERPs in children ages 3–16 years using a naturalistic dichotic listening task.
ERP morphology differed for nonlinguistic versus linguistic probes in attended and unattended stories. Maturational changes were different for nonlinguistic versus linguistic probes. Attention modulated the amplitude of early-latency ERPs and invoked later sustained processes. Auditory Cortex Mapmaking: Principles, Projections, and Plasticity. Maps of sensory receptor epithelia and computed features of the sensory environment are common elements of auditory, visual, and somatic sensory representations from the periphery to the cerebral cortex.
Maps enhance the understanding of normal neural organization and its modification by pathology and experience. They underlie the derivation of the computational principles that govern sensory processing and the generation of perception. Despite their intuitive explanatory power, the functions of and rules for organizing maps and their plasticity are not well understood. Some puzzles of auditory cortical map organization are that few complete receptor maps are available and that even fewer computational maps are known beyond primary cortical areas.

Context-Dependent Encoding in the Human Auditory Brainstem Relates to Hearing Speech in Noise: Implications for Developmental Dyslexia. Figure 1 Stimulus Characteristics and Experimental Design (Top) The spectrogram of the stimulus /da/.
The boundary of the consonant-vowel formant transition and the steady-state vowel portion of the syllable is marked by a dashed white line. The spectrogram was generated via frequency analyses over 40 ms bins starting at time 0, and the midpoint of each bin is plotted. Deciphering auditory processing disorders in children. Decreased temporal precision of neuronal signaling as a candidate mechanism of auditory processing disorder. Open Access Highlights In mouse models of central deafness and APD the cochlea is intact.

Maturation of auditory neural processes in autism spectrum disorder — A longitudinal MEG study. Highlights The first longitudinal study of auditory MEG biomarkers in ASD ASD demonstrates prolonged M100 latencies and reduced transient gamma-band activity. Maturation rates are not different between TD and ASD for M100 latencies. Intermediate M100 latencies and gamma-band activity suggested for “optimal outcome”
