traumatic brain injury resulting road accidents create damage to the brain. the severe brain injury may cause extensive tissue loss of several parenchyma which results in cavities due to primary destruction and secondary injuries such as ischemia and inflammation. recent findings suggest that neuronal precursors in the adult mammalian brain can be a therapeutic target in ischemic brain injuries...

an interesting case of rare multiple hydatid of parotid, brain and kidney is reported. she is a 35-year-old married woman first referred because of a swelling in the parotid region and later for neurological manifestions. on general physical examination, an abdominal mass was felt in the right hypochondrium. these multiple space-occupying 'lesions in the brain, kidney and parotid proved to be h...

Complete mature brain tissue in sacrococcygeal region is a rare congenital anomaly in a newborn, which usually is misdiagnosed for sacrococcygeal teratoma. Glial tumor-like ependymoma is also common in sacrococcygeal area but mostly appears later in life. We present a case of complete heterotopic brain tissue in the sacrococcygeal region. The patient underwent total excision of mass with coccyg...

Introduction: Researchers have long been interested in the effects of low intensity (less than 500 microtesla) and Extremely Low Frequency Magnetic Fields (ELF-MF, less than 300 Hz) on human’s brain activity. In this study, our purpose was to analyze the effect of local magnetic field pulses around brain regions Cz, C3, C4 on human electroencephalogram (EEG) and induction of resonance effect...

Computerised tomography (CT) of pelvis and buttocks revealed a large mass with an irregular outline, measuring 7 cm × 4.3 cm. The lesion contained a few areas of calcification and nonenhancing cystic areas. A lower sacral spina bifida was also noted. There was a soft tissue component within the spinal canal of the lower sacral segment. The bladder was compressed upwards by the lesion (Figure 1)...

Despite recent advances in alternative brain imaging technologies, functional magnetic resonance imaging (fMRI) remains the workhorse for both medical diagnosis and primary research. Indeed, the number of research articles that utilise fMRI have continued to rise unabated since its conception in 1991, despite the limitation that recorded signals originate from the cerebral vasculature rather th...

This paper presents a method for estimating uncertainty in MRI-based brain region delineations provided by fully-automated segmentation methods. In large data sets, the uncertainty estimates could be used to detect fully-automated method failures, identify low-quality imaging data, or endow downstream statistical analyses with per-subject uncertainty in derived morphometric measures. Region seg...

We demonstrated the in vivo feasibility of using focused ultrasound (FUS) to transiently modulate (through either stimulation or suppression) the function of regional brain tissue in rabbits. FUS was delivered in a train of pulses at low acoustic energy, far below the cavitation threshold, to the animal's somatomotor and visual areas, as guided by anatomical and functional information from magn...

Historically, studies of brain metabolism have been based on targeted analyses of a limited number of metabolites. Here we present an untargeted mass spectrometry-based metabolomic strategy that has successfully uncovered differences in a broad array of metabolites across anatomical regions of the mouse brain. The NSG immunodeficient mouse model was chosen because of its ability to undergo huma...
