Developmental dyslexia is a specific disorder in learning to read and spell in spite of adequate educational resources, normal intelligence, no obvious sensory deficits and adequate sociocultural opportunity. Dyslexia is strongly familial, and abundant evidence supports genetic factors in its etiology (6). Three independent genome-wide scans using different analytical approaches have shown linkage of dyslexia to 2p12-p16 (14–16). In our previous genome-wide scan on 11 Finnish pedigrees, we identified linkage to the broad Chromosome 2 DYX3 locus using a categorical phenotype (16).

An Investigation of Methods to Detect Feigned Reading Disabilities. Auditory processing and the development of language and literacy. Abstract This paper considers evidence for basic auditory processing impairments associated with dyslexia and specific language impairment, against a back-drop of findings from studies of the normal development of auditory and phonological processing.
A broad range of auditory impairments have been implicated in the aetiology of these language-learning disorders, including deficits in discriminating the temporal order of rapid sequences of auditory signals, elevated thresholds for frequency discrimination and for detection of amplitude and frequency modulation, impaired binaural processing and increased susceptibility to backward masking.
Current evidence is inconsistent, but suggests that not all children with language difficulties have non-verbal auditory processing impairments, and for those that do, the impact on language development is poorly understood.

Email: firstname.lastname@example.org. Abstract We have recently demonstrated using fMRI that a region within the human lateral occipital complex (LOC) is activated by objects when either seen or touched. We term this cortical region LOtv for the lateral occipital tactile–visual region. Introduction A central theme in sensory neurophysiology is that information processing in primary sensory areas is strictly modality specific.
This finding raises an essential question. We show here that the object-related activation is robust in both the visual and tactile modalities. Materials and Methods MRI Acquisition The BOLD fMRI measurements were performed in a whole-body 1.5 T, Signa Horizon, LX8.25 General Electric scanner, located at the Wohl Institute for Advanced Imaging in the Tel-Aviv Saurasky Medical Center. Experimental Procedure MRI Subjects. Functional genetic analysis of mutations implicated in a human speech and language disorder. Abstract Mutations in the FOXP2 gene cause a severe communication disorder involving speech deficits (developmental verbal dyspraxia), accompanied by wide-ranging impairments in expressive and receptive language.
The protein encoded by FOXP2 belongs to a divergent subgroup of forkhead-box transcription factors, with a distinctive DNA-binding domain and motifs that mediate hetero- and homodimerization. Here we report the first direct functional genetic investigation of missense and nonsense mutations in FOXP2 using human cell-lines, including a well-established neuronal model system.

Email: email@example.com. Abstract The integration of multisensory information is essential to forming meaningful representations of the environment. Adults benefit from related multisensory stimuli but the extent to which the ability to optimally integrate multisensory inputs for functional purposes is present in children has not been extensively examined. Introduction The ability to construct meaningful internal representations of the environment depends on integrating and segregating the myriad multisensory inputs that enter the nervous system at a given moment.
To date, knowledge of the development of the neurophysiological processes that underlie MSI comes largely from animal studies. The genetic basis of the joint hypermobility syndromes. Rheumatologists have long considered that joint hypermobility is inherited.
The familial aggregation is striking and the pattern of inheritance strongly points to an autosomal dominant mode. The first comprehensive description of symptomatic joint hypermobility in the rheumatological literature is attributed to Kirk, Ansell and Bywaters in 1967 . They coined the term ‘hypermobility syndrome’ (HMS). Too Little, Too Late: Reduced Visual Span and Speed Characterize Pure Alexia. Pure alexia is an acquired reading disorder that leaves writing unaffected.
Pure alexic reading is usually slow with single-word reading characterized by a pronounced word length effect; reaction times (RTs) in reading increase linearly with word length, often with hundreds of milliseconds per letter (Behrmann, Plaut, and Nelson 1998). Theories of pure alexia can be roughly divided into 2 groups: 1) Domain-specific accounts, suggesting that pure alexia arises due to damage to a cognitive system or cerebral area specialized for recognizing visual word forms (Warrington and Shallice 1980; Warrington and Langdon 1994; Cohen et al. 2003; Cohen and Dehaene 2004); 2) General visual accounts, claiming that pure alexia reflects a general deficit in visual perception (Farah and Wallace 1991; Behrmann, Nelson, and Sekuler 1998), often conceptualized as a primary impairment in simultaneous perception or parallel processing (Farah, 2004).
