In an extensive review of the literature on reading disability Hallgren (1950) finds a consensus of opinion among most authors that the incidence of severe cases of dyslexia among otherwise normal school-children is about 1% ; and this agrees well with the most recent findingin this country, reported in the Ministry of Education (1950) pamphlet " Reading Ability ", that 1-4% of children leaving...

A brief exposure to rightward prismatic adaptation (PA) was shown to shift visual field representation within the inferior parietal lobule (IPL) from the right to the left hemisphere. This change in hemispheric dominance could be interpreted as (1) a general effect of discrepancy in visuomotor alignment caused by PA or (2) a direction-specific effect of rightward PA. To test these hypotheses, w...

The purpose of our study was to ascertain the degree of correlation between handedness and physiological neocerebellar extinction syndrome demonstrable on the side contra lateral to the dominant upper extremity. Using the Edinburgh questionnaire and other tests for “handedness”, we examined 221 healthy 9–11-year old schoolchildren for handuse preference. To test their handedness the following 6...

Objective: The present study aims to investigate the effect of emotions (negative and positive affects) and gender on the activity of different brain regions and their relationship with personality traits of extraversion, introversion, neuroticism, and stability. Methods: The study participants were 33 right-handed volunteer undergraduate students (17 males and 16 females). Our stimuli were tw...

The neurophysiology underlying the Behavioral Activation and Behavioral Inhibition Systems (BAS and BIS) and the impact of the strength of these systems on affective processing have received increased attention over the last 25 years. Specifically, left-frontal brain regions have been implicated in BAS strength as well as the experience of positive-approach affect (such as happiness). Conversel...

Lateralization of function is a fundamental feature of the human brain as exemplified by the left hemisphere dominance of language. Despite the prominence of lateralization in the lesion, split-brain and task-based fMRI literature, surprisingly little asymmetry has been revealed in the increasingly popular functional imaging studies of spontaneous fluctuations in the fMRI BOLD signal (so-called...

Recent findings raised evidence that in early-onset left temporal lobe epilepsy, women show greater functional plasticity for verbal memory than men. In particular, women with lesion- or epilepsy-driven atypical language dominance show an advantage over men. The question asked in this study was whether there is evidence of sex- and language dominance-dependent late, i.e. adult age, plasticity f...
