Objective: Crocin and safranal, as the major constituents of saffron, have many biological activities. This study investigated the effects of crocin and safranal on yawning response induced by intracerebroventricular (i.c.v.) injection of histamine in rats. Materials and Methods: In ketamine/xylazine-anesthetized rats, a guide cannula was implanted in the right ventricle of the brain and yawnin...

In this paper we deal with a simplified anisotropic rat head phantom development and the investigation of influence white matter on electroencephalogram source localization. The proposed is based cubic cross cell composition combined agar mixture to set desired electrical conductivity ratio. For fabrication phantom, 3D printed technology exploited. Starting from real brain, brain model incorpor...

Background & Aims: Ischemic postconditioning, conducted by a series of brief occlusion and release of the bilateral common carotid arteries, has neuroprotective properties in permanent or transient models of middle cerebral artery (MCA) occlusion but its delayed neuroprotective effects in the embolic model of stroke, especially in female rat, have not yet been reported and were investigated ...

Abstract Various electrophysiological and imaging techniques have been studied for the diagnosis treatment of epilepsy. In particular, electrocorticography (ECoG) provides valuable information that can guide clinical patients with Currently, it is necessary to define benefits ECoG in free-moving animals Here, we present results simultaneous recordings multiple cortical sites responsive neurosti...

Objective(s): Oxytocin is involved in modulation of many brain-mediated functions. In the present study, we investigated the central effects of oxytocin and its receptor antagonist, atosiban on inflammatory pain. The contribution of opiate receptors was explored using non-selective and selective antagonists. Materials and Methods: The fourth ventricle of the brain of anesthetized rats was impla...

Background and objectives: Many Nepeta species have been commonly used in Iranian folk medicine as tranquilizer, relaxant, carminative and restorative tonic for nervous and respiratory disorders. Inflammation is a problem in many diseases and has an important role in brain function that can cause neurodegenerative disorders. Inflamed glial cells can exacerbate neurodegenerative disease...

Introduction: In adult mammalian brain, neural stem cells are isolated from both the dentate gyrus and subventricular zone. This study aimed to isolate neural stem cells from adult rat subventricular zone and differentiate them into neurons and astrocytes.  Methods: In this study, the whole brain was removed after full anesthesia and creating cervical dislocation. Under a microscope, subv...
