The major focus of the Neurosignal Analysis Laboratory (NeurAL) is to perform Neuroimaging based on the multichannel EEG and fMRI measurements.
We work on Source Localization Algorithms for Neuroimaging the Multichannel EEG data recorded from human subjects under the steady-state and/or event-related conditions. We also process the simultaneous EEG - fMRI recordings for image fusion.
The history of EEG based research in the Institute of Biomedical Engineering goes back to the beginning of 1990s with a strong emphasis on signal processing in collobaration with the EEG laboratory at the Department of Physiology in Istanbul Medical School. Early studies were focused on analyzing the EEG data reflecting the human sensory/cognitive behavior under normal physiological and clinical conditions.
By the 2000s, we started to the develop our algorithms for EEG dipole source localization and the accessibility to the fMRI data enabled us to build up an expertise on neuroimaging using EEG and fMRI.
Functional neuroimaging is essentially important to understand how the brain works and, it is the first step how to develop more effective diagnosis and treatment procedures for mental and neurological disorders.
The major aim of our research agenda is geared towards developing new analytical research tools to model the neuroscientific data that will enable us to perform functional neuroimaging of the human brain under sensory and/or cognitive conditions. Also important for us is to design versatile brain computer interfaces by exploiting this knowledge base that will aid the neurologically disabled. Outcome of our research will be to help improve the health care quality by devising noninvasive diagnostic tools that will rely on the maximal exploitation and objective evaluation of the neuroinformatic data.
