Psychophysical correspondence between vibrotactile intensity and intracortical microstimulation for tactile neuroprostheses in rats
(Iop Publishing Ltd, 2017)Objective. Recent studies showed that intracortical microstimulation (ICMS) generates artificial sensations which can be utilized as somatosensory feedback in cortical neuroprostheses. To mimic the natural psychophysical ... -
A Preliminary Model for Operant Conditioning of Rats in a Detection Task
(IEEE, 2016)In this study, we proposed a nonlinear probabilistic model to show how operant conditioning develops in rats trained to detect vibrotactile stimuli on their hindpaw glabrous skin. The model shows the dynamics of neural ... -
A fusion method for pulmonary nodule segmentation in chest CT image sets
(IEEE, 2016)This paper presents a fusion algorithm combining two methods for pulmonary nodule segmentation in Chest CT scans. Segmentation is an important task for both diagnosis and therapy monitoring. Since manual segmentation of ... -
Developing a computer program of laser aplication imaged with fundus fluorescein angiography test for retinal diseases
(Gazi Eye Foundation, 2016)Purpose: The aim was to design a model which facilitates laser treatment for Diabetic Retinopathy and the treatment technique was conducted during education of assistant doctors. Materials and Methods: 127 patients diagnosed ... -
Vibrotactile Sensitivity of Freely Behaving Rats and Operant Conditioning by Intracortical Microstimulation
(IEEE, 2015)In this study, 5 adult Wistar albino rats were trained to detect presence or absence of mechanical vibrations applied on the volar surface of their hindpaws. Vibrotactile sensitivity of glabrous skin of these rats were ... -
Detection of P300 based on Artficial Bee Colony
(SciTePress, 2016)A Brain-Computer Interface (BCI) is a system that allows users to communicate with their environment through cerebral activity. P300 signal, which is used widely in BCI applications, is produced as a response to a stimulus ... -
A novel vibrotactile system for stimulating the glabrous skin of awake freely behaving rats during operant conditioning
(Elsevier Science Bv, 2015)Background: Rat skin is innervated by mechanoreceptive fibers similar to those in other mammals. Tactile experiments with behaving rats mostly focus on the vibrissal system which does not exist in humans. The aim of this ... -
Conspicuity of Peripheral Zone Prostate Cancer on Computed Diffusion-Weighted Imaging: Comparison of cDWI(1500), cDWI(2000), and cDWI(3000)
(Hindawi Ltd, 2014)Introduction and Objective. Disadvantages associated with direct high b-value measurements may be avoided with use of computed diffusion-weighted imaging (cDWI). The purpose of this study is to assess the diagnostic ... -
Astragaloside IV and cycloastragenol production in in vitro produced Astragalus trojanus Stev.
(Natl Inst Science Communication-Niscair, 2015)In the present paper, an efficient method for clonal propagation of an endemic plant, Astragalus trojanus Stev., was described. Effect of sucrose and 6-benzyladenine (BA) concentrations on shoot proliferation and rooting ... -
Microhardness evaluation of enamel adjacent to an improved GIC sealant after different enamel pre-treatment procedures
(Ariesdue Srl, 2014)Aim This in vitro study was carried out to evaluate the microhardness of enamel adjacent to a glass ionomer cement (GIC) with high fluoride content used as a sealant (Fuji Triage, GC Corp., Japan) after laser, bur or air ... -
Modeling Cortical States By Spiking Neurons
(IEEE, 2014)Computational neuroscience has been effective in providing tools for investigation of cognitive processes along with neurode generative diseases and neurological disorders, recently. In this work, it will be shown that it ... -
Silkfibroin-Ca-P Composite Bone Replacement Material for Guided Bone Growth
(Aalborg Univ Press, 2015)Mineralized natural protein based materials are investigated as novel materials to be used in tissue engineering and as bone replacement materials. Silk fibroin fiber based foams and films are used as mineralized composites ... -
Minimum Spanning Tree Reflects the Alterations of the Default Mode Network During Alzheimer's Disease
(Springer, 2011)This study analyzes the connectivity pattern of the default mode network (DMN) in patients with Alzheimer's disease (AD) in comparison with young and elderly controls using the minimum spanning tree (MST). This tree is a ... -
Asymmetric response properties of rapidly adapting mechanoreceptive fibers in the rat glabrous skin
(Informa Healthcare, 2013)Previous histological and neurophysiological studies have shown that the innervation density of rapidly adapting (RA) mechanoreceptive fibers increases towards the fingertip. Since the psychophysical detection threshold ... -
Alkaline and acidic anodization of titanium implants using electrochemistry
(IEEE, 2014)Recent advancements in the medical field has lead to the prolongation of life expectancy and an increase in the elderly population. Consequently, the deterioration of bone health and a shift towards carbohydrate-based ... -
Investigation of the default mode network of the brain during Alzheimer's disease by minimum spanning tree
(2011)This study analyzes the connectivity pattern of the default mode network (DMN) in patients with Alzheimer's disease (AD) in comparison with young and elderly controls using the minimum spanning tree (MST). The findings ... -
Graph theoretical analysis of functional brain networks during Alzheimer's disease
(2010)In this study the functional magnetic resonance imaging data from Alzheimer's patients and nondemented older adults are investigated using graph theory. Voxel-based graphs were built on the data obtained from an international ... -
