Hypoparathyroidism, sensorineural deafness and renal dysplasia (HDR) syndrome is an autosomal dominant disorder (1). We herein demonstrate the brain computed tomography (CT) findings of a 31-year-old woman with HDR syndrome caused by a GATA3 heterozygous mutation (2). Her 1-year-old son had renal cystic dysplasia. Brain CT revealed bilateral and symmetrical calcifications in the basal ganglia, ...

The acquisition of new motor skills is dependent on task practice. In the case of motor transfer, learning can be facilitated by prior practice of a similar skill. Although a multitude of studies have investigated the brain regions contributing to skill acquisition, the neural bases associated with the savings seen at transfer have yet to be determined. In the current study, we used functional ...

In bimanual object manipulation tasks, people flexibly assign one hand as a prime actor while the other assists. Little is known, however, about the neural mechanisms deciding the role assignment. We addressed this issue in a task in which participants moved a cursor to hit targets on a screen by applying precisely coupled symmetrical opposing linear and twist forces on a tool held freely betwe...

Each language has a unique set of phonemic categories and phonotactic rules which determine permissible sound sequences in that language. Behavioral research demonstrates that one's native language shapes the perception of both sound categories and sound sequences in adults, and neuroimaging results further indicate that the processing of native phonemes and phonotactics involves a left-dominan...

Cognitive development and learning are characterized by diminished reliance on effortful procedures and increased use of memory-based problem solving. Here we identify the neural correlates of this strategy shift in 7-9-year-old children at an important developmental period for arithmetic skill acquisition. Univariate and multivariate approaches were used to contrast brain responses between two...

OBJECTIVE To develop a clinically applicable memory functional MRI (fMRI) method of predicting postsurgical memory outcome in individual patients. METHODS In this prospective cohort study, 50 patients with temporal lobe epilepsy (23 left) and 26 controls underwent an fMRI memory encoding paradigm of words with a subsequent out-of-scanner recognition assessment. Neuropsychological assessment w...
