Hemispatial neglect is a common and disabling consequence of stroke. Previous reports examining the relationship between gender and the incidence of unilateral spatial neglect (USN) have included either a large numbers of patients with few neglect tests or small numbers of patients with multiple tests. To determine if USN was more common and/or…

The Virchow-Robin spaces (VRS), perivascular compartments surrounding small blood vessels as they penetrate the brain parenchyma, are increasingly recognized for their role in leucocyte trafficking as well as for their potential to modulate immune responses. In the present study, we investigated VRS numbers and volumes in different brain regions…

Six years have gone by since the passing of "No Child Left Behind" (2002) and due to the "high-stake" riders attached to this legislation, educators at all levels have found themselves in a state of both emotional and cognitive dissonance. Recent research in the field of neuroscience combined with principles gained from…

We tested the hypothesis that prenatal masculinization of the brain by androgens increases risk of developing an autism spectrum condition (ASC). Sex-typical play was measured in n = 66 children diagnosed with an ASC and n = 55 typically developing age-matched controls. Consistent with the hypothesis, girls with autism did not show the…

Immordino-Yang's description of the unexpected recovery of 2 boys with severe brain trauma is an example of the interplay between the plasticity of the brain and the plasticity of the context. It highlights the dynamics of "wants and cans" and the specific role of motivation in this dynamic. As an example of how this dynamic can evolve in…

The article by Carota and Sirigu addresses a fundamental issue, namely the domain specificity of people's ability to learn and implement sequential structures of events. The authors review theoretical positions and empirical findings related to this issue, providing a useful summary of representative models of sequential event structures, and a…

Although parents and children are thought to influence one another's affect and behavior, few studies have examined the direction of effects from children to parents, particularly with respect to parental psychopathology. We tested the hypothesis that children's affective characteristics are associated with the course of mothers' depressive…

We used fMRI to directly compare activation in two cortical regions previously identified as relevant to real-world scene processing: retrosplenial cortex and a region of posterior parahippocampal cortex functionally defined as the parahippocampal place area (PPA). We compared activation in these regions to full views of scenes from a global…

Children born preterm exhibit working memory deficits. These deficits may be associated with structural brain changes observed in the neonatal period. In this study, the relationship between neonatal regional brain volumes and working memory deficits at age 2 years were investigated, with a particular interest in the dorsolateral prefrontal…

The aim of the present study was to examine the communicative abilities of traumatic brain injury patients (TBI). We wish to provide a complete assessment of their communicative ability/disability using a new experimental protocol, the "Assessment Battery of Communication," ("ABaCo") comprising five scales--linguistic, extralinguistic,…

The bulk of the research on the neural organization of metaphor comprehension has focused on nominal metaphors and the metaphoric relationships between word pairs. By contrast, little work has been conducted on predicate metaphors using verbs of motion such as "The man fell under her spell." We examined predicate metaphors as compared to literal…

Recent evidence suggests that rats require an intact hippocampus in order to recognize familiar objects when they encounter them again in a different context. The two experiments reported here further examined how changes in context affect rats' performance on the novel-object preference (NOP) test of object-recognition memory, and how those…

The effect of deep brain stimulation on the two speech-production subsystems, articulation and phonation, of nine Parkinsonian patients is examined. Production parameters (stop closure voicing; stop closure, VOT, vowel) in fast syllable-repetitions were defined and measured and quantitative, objective metrics of vocal fold function were obtained…

Cognitive control of behavior continues to improve through adolescence in parallel with important brain maturational processes including synaptic pruning and myelination, which allow for efficient neuronal computations and the functional integration of widely distributed circuitries supporting top-down control of behavior. This is also a time when…

Auditory word comprehension was assessed in a series of 289 acute left hemisphere stroke patients. Participants decided whether an auditorily presented word matched a picture. On different trials, words were presented with a matching picture, a semantic foil, or a phonemic foil. Participants had significantly more trouble with semantic foils…
