PURPOSE The present study was carried out to identify how gum chewing with and without occlusal support by implant prostheses affects brain function as well as chewing function. METHODS Twenty-four subjects rehabilitated with implant-supported fixed prostheses were evaluated. An electroencephalograph (EEG) (ESA-Pro) and mandibular kinesiograph (Bio PAK(®)) wear used to measure brain function ...

traumatic brain injury (tbi) is described by a disruption in the normal function of the brain due to an injury following a trauma, which can potentially cause severe physical, cognitive, and emotional impairment. the use of human stem cells and self-assembling peptide scaffolds suggest huge potential for application in the treatment of tbi. in the present study, we surveyed the beneficial effec...

anosmia following head trauma is relatively common and in many cases is persistent and irreversible. the ability to objectively measure such a decline in smelling, for both clinical and medicolegal goals, is very important. the aim of this study was to find results of brain single photon emission computed tomography (spect) in anosmic subjects after closed head trauma. this case-control cross s...

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 fo...

brain hydatid cyst constitutes one of the leading causes of cranial mass in the endemic region, especially among the children. symptoms of the disease are associated with rising of intracranial pressure and focal neurological deficit. surgical excision of the cyst is essential to treatment. here we present a 19 yr-old male livings in ardabil, northwest of iran, referred to neurosurgery clinic i...

Background and Aim: DTI-based tractography could help us to visualize the spatial relation of fiber tracts to brain lesions. Several factors may interfere with the procedure of diffusion-based tractography, especially in brain tumors. The aim of the current study is to discuss several solutions to improve the procedure of fiber reconstruction adjacent or inside brain lesions. Illustrative cases...

Objective(s) Psychotropic medications produce their effects, in part, through increasing neurotrophin levels in the brain. Since studies concerning nerve growth factor (NGF) analysis have been limited in scope, in the current experiments we investigated the effects of diverse psychotropic agents on NGF protein levels in various brain regions of rat. Materials and Methods Male Wistar rats rec...
