background: amniotic membrane derived stem cells (amscs) have considerable advantages to use in regenerative medicine and their anti- inflammatory effects, growth factor secretion and differentiation potential make them suitable candidates for stem cell therapy of nervous system. the developing and neonatal brain contains a spectrum of growth factors to direct development of endogenous and dono...

To derive tests for randomness, nonlinear-independence, and stationarity, we combine surrogates with a nonlinear prediction error, a nonlinear interdependence measure, and linear variability measures, respectively. We apply these tests to intracranial electroencephalographic recordings (EEG) from patients suffering from pharmacoresistant focal-onset epilepsy. These recordings had been performed...

In this paper, we describe a human-computer interface (HCI) system that includes an enabler for controlling gadgets based on signal analysis of brain activities transmitted from the enabler to the gadgets. The enabler is insertable in a user’s ear and includes a recorder that records brain signals. A processing unit of the system, which is inserted in a gadget, commands the gadget based on deco...

Objective: In this research, a new approach termed as “evolutionary-based brain map” is presented as a diagnostic tool to classify schizophrenic and control subjects by distinguishing their electroencephalogram (EEG) features.Methods: Particle swarm optimization (PSO) is employed to find discriminative frequency bands from different EEG channels. By deploying the energy of those selected fr...

Brain decoding is an emerging approach for understanding the face perception mechanism in human brain. Face visual stimuli and are considered as a challenging ongoing research of neuroscience field. In this study, face/scrambled stimulations were implemented over sixteen participants to be decoded or scrambled classification using machine learning (ML) algorithms via magnetoencephalography (MEG...

Submit Manuscript | http://medcraveonline.com Hunger and satiety are generally regulated by the central nervous system (CNS) via the gut-brain axis and a number of hormones play critical roles in body weight management [3,4]. Among these hormones, the three most important hormones are leptin, ghrelin and insulin [5]. Leptin is a hormone secreted by fat cells which sends negative feedback signal...

aim and background:   stress of surgery transfers some neurological and hormonal signals which triggers some physiological responses like adrenergic stimulation, increase in noradrenalin, cortisol, growth factor, decrease in insulin and increase in insulin resistance resulting in hyperglycemia during surgery. in this study a comparison is done between general anesthesia which by blocking brain&...

We present here a systematic mapping of nAChR subunit mRNAs in Macaca mulatta brain. A fragment, from the transmembrane segments MIII to MIV of Macaca neuronal nAChR subunits was cloned, and shown to exhibit high identity (around 95%) to the corresponding human subunits. Then, specific oligodeoxynucleotides were synthesized for in situ hybridization experiments. Both alpha4 and beta2 mRNA signa...

Background: Carbon monoxide (CO) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. Magnetic resonance imaging (MRI) has a well-recognized role in assessment of the severity of brain damage caused by CO poisoning. In this study, we aimed to present and analyze the structural abnormalities in the brain MRI and especially in diffusion weighted MRI (DWI) images in ...

Despite many years of research on the neural correlates of consciousness (NCCs), it is still unclear how the detailed contents of consciousness are represented in the human brain. It is often assumed that specific contents of consciousness are encoded in dedicated core NCCs - one for each different aspect of conscious experience. Now, the approach of multivariate decoding provides a novel frame...
