Vision is the dominant sense, and the eyes are connected with almost every other part of the brain. If the vision system is poorly developed, children trying to learn suffer. Without good up close vision, students are handicapped even if no one knows or suspects it--they may not even know it themselves. Students do not know that the way they see…

A number of muscular dystrophies are associated with the defective glycosylation of [alpha]-dystroglycan and many are now known to result from mutations in a number of genes encoding putative or known glycosyltransferases. These diseases include severe forms of congenital muscular dystrophy (CMD) such as Fukuyama type congenital muscular dystrophy…

The role of morphological, semantic, and form-based factors in the early stages of visual word recognition was investigated across different SOAs in a masked priming paradigm, focusing on English derivational morphology. In a first set of experiments, stimulus pairs co-varying in morphological decomposability and in semantic and orthographic…

A number of previous studies have indicated that Broca's area has an important role in understanding and producing syntactically complex sentences and other language functions. If Broca's area is critical for these functions, then either infarction of Broca's area or temporary hypoperfusion within this region should cause impairment of these…

The conflict monitoring model of M. M. Botvinick, T. S. Braver, D. M. Barch, C. S. Carter, and J. D. Cohen (2001) triggered several research programs investigating various aspects of cognitive control. One problematic aspect of the Botvinick et al. model is that there is no clear account of how the cognitive system knows where to intervene when…

Recent work has shown that Whorf effects of language on color discrimination are stronger in the right visual field than in the left. Here we show that this phenomenon is not limited to color: The perception of animal figures (cats and dogs) was more strongly affected by linguistic categories for stimuli presented to the right visual field than…

Two studies were carried out to investigate the effects of presentation of primes showing partial (word-initial) or full overlap on processing of spoken target words. The first study investigated whether time compression would interfere with lexical processing so as to elicit aphasic-like performance in non-brain-damaged subjects. The second study…

Background: Prader-Willi syndrome (PWS) is a genetic disorder associated with intellectual disabilities, compulsivity, hyperphagia and increased risks of life-threatening obesity. Food preferences in people with PWS are well documented, but research has yet to focus on other properties of food in PWS, including composition and suitability for…

The ventromedial prefrontal cortex (vmPFC) and insular cortex are implicated in distributed neural circuitry that supports emotional decision-making. Previous studies of patients with vmPFC lesions have focused primarily on decision-making under uncertainty, when outcome probabilities are ambiguous (e.g. the Iowa Gambling Task). It remains unclear…

Change of first language (L1) status from the most stable language to a less accessible language over the life-span of a bilingual individual is termed "language attrition". Such a shift in ease of L1 access has been reported to affect the lexicon (Pelc, 2001) more than other aspects of language. However, whether L1 attrition is affected by…

Recognized as the definitive reference in the field, this book addresses a broad range of biologically based disorders that affect children's learning and development. Leading authorities review the genetics of each disorder; its course and outcome; associated developmental, cognitive, and psychosocial challenges; and what clinicians and educators…

Background: Globalization in medical education often means a "brain drain" of desperately needed health professionals from low- to high-income countries. Despite the best intentions, partnerships that simply transport students to Western medical schools for training have shockingly low return rates. Ethiopia, for example, has sent…

In her new book, popular author Ann Lewin-Benham draws on her intimate knowledge and experience with the Reggio Approach to present 12 "best practices" inspired not only by Reggio, but also by play-based and Montessori approaches to early childhood education. These practices are demonstrated, one per chapter, with scenarios from classrooms,…

Background: Although autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) are two distinct neurodevelopmental diseases, they share behavioural, neuropsychological and neurobiological characteristics. For the identification of endophenotypes across diagnostic categories, further investigations of phenotypic overlap…

Excessive production of pro-inflammatory mediators by activated brain microglia plays an important role in abnormal neuronal function and cognitive deficits. Studies have shown that the intake of flavonoids is inversely related to cognitive decline and dementia in people 65 years of age or older. Luteolin, a flavonoid found in high concentrations…
