We observed the characteristics of white matter fibers and gray matter in multiple sclerosis patients, to identify changes in diffusion tensor imaging fractional anisotropy values following white matter fiber injury. We analyzed the correlation between fractional anisotropy values and changes in whole-brain gray matter volume. The participants included 20 patients with relapsing-remitting multi...

BACKGROUND AND PURPOSE The thermogenesis of BAT is believed to be controlled through some pathways initiated in the brain, though the changes in brain activity among different states of BAT-positive subjects are still unclear. We hypothesized that some significant differences of regional cerebral metabolism between various groups were related to the BAT activities regardless of temperature chan...

BACKGROUND Unusual symptoms such as digit misidentification and neglect-like phenomena have been reported in complex regional pain syndrome (CRPS), which we hypothesized could be explained by parietal lobe dysfunction. METHODS Twenty-two patients with chronic CRPS attending an in-patient rehabilitation programme underwent standard neurological examination followed by clinical assessment of pa...

The aims of the present study were to investigate regional cerebral blood flow (rCBF) in heroin-dependent patients during withdrawal and to assess the relation between these changes and duration of heroin consumption and withdrawal data. The rCBF was measured using brain SPECT with 99mTc-HMPAO in 16 heroin-dependent patients during heroin withdrawal. Thirteen patients received levomethadone at ...

meningioma is usually a benign central nervous system (cns) tumor. metastasis is rare; however if it does occur the most metastatic sites are the liver and lungs. here, two cases of cns meningioma with metastasis to cervical lymph nodes are reported. the first case, a 48 year-old man developed cervical lymph node metastasis nine years after primary tumor diagnosis. the second case, a 23 year-ol...

asterixis, firstly described in metabolic encephalopathies, may occur unilaterally in patients with various focal brain diseases. although hardly localizing, most reported cases have showed a contralateral thalamic pathology; but lesions in the medial frontal lobe, parietal lobe, brain stem, basal ganglia, insular lesions, may also cause unilateral asterixis. in this article, three cases of acu...

This study aimed to answer the questions ‘What are neural networks and mechanisms involved in visual kinesthetic motor imagery?’, ‘Is part of cognitive processing included during imagery?’ by investigating neurophysiological activations imagery using tasks (golf putting). The experiment was conducted with 19 healthy adults. Functional magnetic resonance imaging (fMRI) used examine golf putting ...

Background: parietal lobe is an important area of the brain involved in a number of higher cortical functions. Anatomy descriptions differ with regard to the classical ways, making the location of the elements that compose the imprecise parietal lobule. Objective: To develop a method of location nine references in the parietal lobe, analyze the reliability of this method when using the techniqu...
