The development of hemispherectomy for glioma (mostly in adults) by Dandy (1928) and later for infantile hemiplegia by Krynauw (1950) permitted comparisons of effects of removal of either hemisphere on both the adult and young brain. Reviews of over 300 cases of hemispherectomy (e.g., White, 1961; McFie, 1961) reflect the 'functional plasticity' of the young brain. Continuing development of hig...

Gerstmann’s syndrome is caused by a left (dominant) inferior parietal lesion, particularly involving the angular gyrus or subjacent white matter of the left hemisphere. We describe case of an 80 year old right handed man admitted to our hospital with history of sudden onset of blurred vision. At first in neurological examination, he had left hemonymus hemianopia and characteristic features of G...

Background and Aim: Human brain research in recent years has demonstrated the existence of mirror neurons in Brodmann areas (BA) 44, 6, and BA40. However, there has been almost no previous research on swallowing and mirror neurons. We have investigated the activity of mirror neurons during swallowingrelated visual stimulation. Subjects and Methods: Subjects were 15 healthy individuals (6 male, ...

BACKGROUND A right handed man with trauma to the head was admitted with headache and seizures. A severe right sided weakness was noted after a blunt trauma to the right side of his head. METHODS AND RESULTS MRI of brain revealed a right-sided subdural hematoma and a normal left hemisphere and downstream motor pathways. Bimanual simultaneous drawing and manual reaction times indicated that the...

Background: Palliative whole brain radiotherapy (WBRT) has been the standard treatment for brain metastases. Ionizing radiation is known to be one of the most potent cataractogenic agents. We aimed to evaluate two different radiotherapy techniques with respect to the doses received by the organs at risk (OAR) in patients with brain metastasis who undergone WBRT. Materials and Methods: Ten conse...

In this paper, we attempt to draw comparisons between our research experiences of Computer Supported Collaborative Learning in the workplace, in schools and in universities. We present an outline description of our activities in each setting. As a possible contribution to foundational theory in CSCL, we focus on the crucial but complex issue of learner motivation. We argue that the dominant iss...
