It is an Intensive 1-day course for introducing utilizing transcranial direct current stimulation (tDCS) in an applied format. This technique is a noninvasive brain stimulation that uses direct electrical currents over the head to stimulate specific parts of the brain which modulates neuronal activity. It has strong potentiality in the field of medical and neuroscientific research. Anodal stimu...

Multiple sclerosis is a de-myelinating inflammatory condition of the central nervous system that is often thought of as an autoimmune disorder. These patients suffer from extensive cognitive impairments such as poor attention and concentration and memory and processing speed; Therefore, the aim of this study was to investigate the anodic effect of direct cortical electrical stimulation (tDCS) o...

Abstract Stimulation of axons or its avoidance plays a central role for neuroprosthetics and neural-interfaces research. One peculiar example constitutes retinal implants. Retinal implants aim to artificially activate ganglion cells (RGCs) via electrical stimulation. Such stimulation, however, often generates undesired stimulation RGC axon bundles, which leads distorted visual percepts. In orde...

Introduction: Low-frequency stimulation (LFS) has a delaying effect on kindled seizures acquisition. In the present study we examined the role of galanin receptors in the inhibitory effects of LFS on kindled seizures induced by electrical stimulation of perforant path. Methods: Animals were stimulated daily at the AD threshold intensity with a rapid kindling procedure. LFS was applied immed...

The bed nucleus of the stria terminalis (BST) has been known to contain estrogen (E)-concentrating neurons. In addition, injections of E into BST have been reported to potentiate the sympathoinhibitory arterial pressure (AP) and heart rate (HR) responses elicited by glutamate (Glu) stimulation. In this study, the effect of glutamate antagonist receptors in the rostral ventrolateral medulla (RVL...

Background : Non-Stress Test (NST) is one of the most common methods used to evaluat fetus health, which its results are presented as reactive and non-reactive. One of the limitations of this test is the high number of false non-reactive cases. Different studies have suggested a combination of vibroacoustic stimulation and NST to reduce the number of non-reactive cases and duration of the test....

 Introduction: Anodal transcranial direct current stimulation (a-tDCS) of the primary motor cortex (M1) has been shown to be effective in increasing corticomotor excitability.  Methods: We investigated whether longer applications of a-tDCS coincide with greater increases in corticomotor excitability compared to shorter application of a-tDCS. Ten right-handed healthy participants received one se...

Introduction: Recent studies have revealed the possibility of learning skills through alternative methods and repetitive tactile stimulation without explicit training. This study aimed to examine the effect of involuntary tactile stimulation on the memory and creativity of healthy participants. Methods: A group of 92 right-handed students participated in this study voluntarily. They were assig...
