introduction: it is clear that the proliferation, migration and differentiation processes of embryonic fetal neural tissue are dependent on special trophic factors. these factors are absent or lessl seen in adult tissue. in this research the effects of fetal brain extract (fbe) on the regenerational processes of lesioned prepheral nerve were investigated. materials and methods: the facial nerve...

background & importance: our study was performed based on the first case, reported in english, of a patient with three contemporary lesions, an extra-axial malformation and two vascular ones. case presentation: a 62-year-old man referred to our clinic due to right hand tremor associated to a slowing of idea-forming function and movements. the neuroradiological evidence showed a right fronto-tem...

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...

Brain imaging techniques allow the mapping of cognitive functions onto neural systems, but also the understanding of mechanisms of human behavior. In a series of imaging studies we have described a minimal neural architecture for imitation. This architecture comprises a brain region that codes an early visual description of the action to be imitated, a second region that codes the detailed moto...

traumatic brain injury (tbi) is one the most common cause of disability between young adults. these people have been socially isolated during post-surgery traumatic brain injury. in this study we investigated the effect of social isolation on the structural deficits after tbi in the young rats. young rats were divided into control group with social interaction, sham group with social isolation ...

In children, tumours of the central nervous system comprise 20% of all tumours and are second most common after leukaemia. Unlike adults, almost half of all the paediatric brain tumours are in the Infratentorial region as shown in table 1. In the infratentorial region, the common tumours are medulloblastoma, low grade cerebellar astrocytoma, brain stem glioma and ependymoma. In the supratentori...

Multiple injury-causing mechanisms, such as wave propagation, skull flexure, cavitation, and head acceleration, have been proposed to explain blast-induced traumatic brain injury (bTBI). An accurate, quantitative description of the individual contribution of each of these mechanisms may be necessary to develop preventive strategies against bTBI. However, to date, despite numerous experimental a...

Atlases of the rat brain are widely used as reference for orientation, planning of experiments, and as tools for assigning location to experimental data. Improved quality and use of magnetic resonance imaging (MRI) and other tomographical imaging techniques in rats have allowed the development of new three-dimensional (3-D) volumetric brain atlas templates. The rat hippocampal region is a commo...
