Experimental and model based investigation of period doubling phenomenon in human steady state visual evoked potential responses
(Bilkent University, 2018-07)Objective. Previous human Steady State Visual Evoked Potential (SSVEP) experiments have yielded different results regarding the range of stimulus frequencies in which Period Doubling (PD) behavior is observed. There also ... -
Experimental and model based investigation of the effects of high stimulus presentation rate on code-modulated visual evoked potential based brain-computer interfaces
(Bilkent University, 2018-09)Objective. Previous studies on code-modulated visual evoked potentials (c- VEP) have yielded important results regarding the performance of c-VEP based brain-computer interfaces (BCIs) in recent years. Since, speed is ... -
Improvement and comparison of complex B₁ mapping techniques for use in MREPT
(Bilkent University, 2018-09)Impedance imaging, (i.e., conductivity, , and permittivity, ) provides helpful information about contrast between healthy and malignant tissues. As one of the impedance imaging techniques, Magnetic Resonance Electrical ... -
Iterative fitting approach to CR-MREPT
(Bilkent University, 2019-06)Electrical properties (conductivity, and permittivity, ) imaging, reveals information about the contrast between tissues. Magnetic Resonance Electrical Properties Tomography (MREPT) is one of the electrical properties ... -
Low convective field artifact elimination using dielectric padding and multichannel receive in cr-MREPT conductivity images
(Bilkent University, 2018-08)Imaging the electrical conductivity of the tissues in RF frequencies is an important tool for medical diagnostic purposes along with the local specific absorption rate estimation that is closely related to MR safety ... -
New approach for designing cVEP BCI stimuli based on superposition of edge responses
(Bilkent University, 2020-01)Electroencephalography (EEG) based brain-computer interfaces (BCIs) are widely used in the field of neural engineering, due to their portability, noninvasive nature, and high temporal resolution properties. Among the different ...
