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...

Brain stimulation techniques are important in both basic and clinical studies. Majority of well-known brain stimulating techniques have low spatial resolution or entail invasive processes. Low intensity focused ultrasound (LIFU) seems to be a proper candidate for dealing with such deficiencies. This review recapitulates studies which explored the effects of LIFU on brain str...

low frequency stimulation (lfs) is a potential alternative therapy for epilepsy. however, it seems that the anticonvulsant effects of lfs depend on its target sites in the brain. thus, the present study was designed to compare the anticonvulsant effects of lfs administered to amygdala, piriform cortex and substantia nigra on amygdala kindling acquisition. in control group, rats were kindled in ...

Background: Pain is of stressful and unpleasant procedures after daily dressing of burn wound, so that if the burn pain is not alleviated properly, it can cause harmful effects other than discomfort. There is evidence that cathodal stimulation of somatosensory cortex can be effective in relieving acute pain. Aim: The main purpose of this study was to determine the effect of Direct Transcranial ...

Introduction: The role of estrogen in the stimulation of gonadotropin-releasing hormone (GnRH) neurons is clear. These neurons do not express estrogen alpha receptors, so other mediator neurons should be present to transmit the positive feedback effect of estrogen to the GnRH neurons. Kisspeptin neurons have an important role in the stimulation of GnRH neurons, so they can be the mediator of...

  Background : Deep brain stimulation (DBS) of the globuspallidusinternus (GPi) is recommended as a promising technique for the management of the primary generalized dystonia (PGD) with DYT1 gene mutation. We present the first report of DBS results in Iranian patients with DYT1 positive PGD.   Methods : Nine patients who suffered from severely disabling DYT1 positive PGD consecutively were recr...

Introduction & Objective: Repetitive transcranial magnetic stimulation (rTMS) is an electro physiologic brain stimulation and integration technique that can change the cortical excitability of the target area in the brain and modulate the nervous and muscular ductility. Addiction is associated with dysfunction of the dorsolateral prefrontal cortex (DLPFC) and altered cerebral oscillations. Acco...
