Objective: To investigate the effect of a home-based interactive telerehabilitation program on balance performance in older people, and to compare the results with a nonsupervised home exercise (NHE) program. Subjects and Methods: A total of 50 participants (35 females), aged 65-90 years, were included in the study. The subjects were randomly assig...
Article
Aims and Objectives: The aim of this study was to investigate the difference between sensory brain responses of nonpainful tactile stimuli applied to the fingers of the right-hand dominant individuals between the hemispheres. Materials and Methods: Nineteen healthy volunteers (9 women, mean age ± standard deviation: 23.00 ± 2.24 years) participated...

Objective: Although many studies are investigating the effects of stimuli on sustained attention performance, only a few studies compare auditory, visual and neutral conditions. Thus, this study aimed to investigate the effect of visual and auditory stimuli on performance during sustained attention task. Materials and Methods: Twenty-six volunteers...
Article
The functions of the sensory systems on disabled people have been one of the most investigated topics in brain research. In these studies, mostly visual stimuli had been employed while investigating the deaf participants. Limited number of electrophysiological studies revealed better visual sensory processing in deaf participants. On the other hand...
Article
Parkinson's Disease (PD) is a common neurodegenerative disorder affecting the function of dopaminergic cells in basal ganglia. Besides the motor symptoms, tremor, and dysfunction of sensory systems. In the literature, there was limited studies which investigates the basic sensorial processing in PD. Therefore, we aimed to establish the sensorial pr...

Objective:The need for sleep is universal and its function is not completely clarified. Daytime alertness decreases after midday and one of the ways of preventing this decrease is daytime napping. The aim of this study is to investigate the effects 60-minutes appetitive daytime napping on cognitive performance.Materials and Methods:This study was c...
Article
Schizophrenia has been recently increasingly linked with a number of structural brain morphological changes which can be associated with functional deficiencies. The aim of this study is to relate electrophysiological changes with structural reduction of Heschl's gyrus (HG) volume in schizophrenia. Fifteen schizophrenia patients were compared with...

The dichotic listening (DL) paradigm has an important role in brain asymmetry studies at the behavioral level. In dichotic listening, the subjects are alerted by diotic or dichotic stimuli which are meaningless, consonant vowel syllables on both ears. The subjects then presented the syllable they heard through a 6 button keypad. During this procedu...
Article
In this study, a low-cost data acquisition (DAQ) system has been developed to measure the body temperature from multiple points using a sensor network approach. This system collects raw data with long-term recording and stores for further analysis. Contact and non-contact types of temperature sensors were used. The system was especially designed fo...

Three dimensional modeling and simulation software are becoming more widespread in medical applications. Enabling the user to view the 3D models of biological tissues and materials, to interact with the models with the ability to observe the reaction of the models to different force loading conditions in a virtual environment are the main propertie...
Article
Objective: The goal of this study was to investigate the changes in the responses to auditory stimuli, which were sorted according to the Bispectral Index (BIS) during sleep. This is the first known research study that incorporated full-scale analysis of sleep auditory evoked potentials (AEP) under the scope of BIS. Material and Methods: The measur...
Article
The goal of this study is to scrutinize the changes in electrophysiological responses to simple and complex auditory stimulations in REM sleep using Bispectral index (BIS) system besides Rechtschaffen and Kales (R&K) scoring system. Twelve healthy subjects participated in the study. Recordings have been performed with 40 channel NuAmps [Electroence...
Conference Paper
Perception of voices of different genders by male and female individuals is in the research scope of many science areas. In this study, consonant-vowel syllables vocalized by baritone and soprano are presented to participants separately in the same session. In the dichotic application, homonymous or heteronymous syllable combinations are presented...
Article
In this paper, the effect of acoustical and electromagnetic (EM) noise sources on the electrophysiological recordings related to brain functions have been investigated. As a seperate issue, the effect of EM noise during operation which influence the patient, anesthesia and surgery teams was also targeted. The results indicate (16 operation sessions...
Article
The present study provides results in an early sleep period for non-REM stage correlation with bispectral index (BIS) values. The purpose of the study was to assess the applicability of an objective procedure to monitor sleep. Nine healthy subjects (mean age: 25.0 ± 4.4; 1 female) were recruited for the study without history of any neurological, ps...
Article
Objective: In this study, a non-invasive dichotic listening paradigm was used during EEG recording in order to evaluate one of the asymmetrical brain functions, the perception of syllables. Method: Twenty healthy volunteers (mean age 21.15 years) were recruited in the study. The EEG measurements were performed on 64 channels, five of which were pri...

Electrophysiological Assessment of Brain Asymmetry Using a Dichotic Listening Paradigm. Objective: In this study, a non-invasive dichotic listening paradigm was used during EEG recording in order to evaluate one of the asymmetrical brain functions, the perception of syllables. Method: Twenty healthy volunteers (mean age 21.15 years) were recruited...
