INVESTIGATING CAUSAL INTERACTIONS IN THE HUMAN BRAIN USING EEG AND fNIRS
(2016-08-24)It is necessary for distributed neural assemblies to work in collaboration to achieve the most elementary brain functions. Activities within segregated neural assemblies are integrated to process an incredibly diverse ... -
INVESTIGATION OF COPLING STRENGTH AND DIRECTIONALITY BETWEEN EEG AND FNIRS AT RESTING STATE USING PERMUTATION CONDITIONAL MUTUAL INFORMATION
(2016-08-26)The motivation of study is to combine multimodality approach EEG-fNIRS to study relationship between neural activity and hemodynamic response applying information theory concepts. Investigating human brain function can be ... -
INVESTIGATION OF FUNCTIONAL CONNECTIVITY AND NEUROVASCULAR COUPLING IN DIFFERENT VIGILANCE / BREATH-HOLD STATES OF THE BRAIN FROM SIMULTANEOUS EEG-fNIRS MEASUREMENTS
(2019-07-10)Functional connectivity and neurovascular coupling are important phenomena that occur in the brain. Functional connectivity is the study of functional brain networks and their characteristics. While neurovascular coupling ... -
INVESTIGATION OF PREFRONTAL COGNITION RESPONSES TO TRANSCRANIAL LASER STIMULATION IN PTSD USING FUNCTIONAL NEAR INFRARED SPECTROSCOPY
(2016-05-31)In recent years low level laser therapy (LLLT) has been of great research interest because of its therapeutic applications in psychiatry, neurology and ophthalmology. In-vivo transcranial delivery of LLLT has shown to ... -
Mapping of Electroencephalogram (EEG) Responses to Newsvendor Decision Model and Cerebral Hemodynamic Responses to Transcranial Photobiomodulation (tPBM) in Humans
(2022-05-17)Decision-making is one of the most critical activities of human beings. Various studies have investigated the brain responses to a variety of decision tasks by deploying the EEG data. The first aim of my dissertation was ... -
Novel Quantification of Neurovascular Coupling (NVC) to Predict Brain Injury in Neonates with Hypoxic Ischemic Encephalopathy
(2020-09-04)Birth asphyxia is a global burden in clinical neonatal care. It results from deprivation of oxygen to a newborn infant that lasts too long during the birth causing physical harm to the brain. The asphyxia insult impairs ... -
Proposing a Sparse Weighted Directed Network Construction Method and a Novel Mutual-Information based Sparse Feature Selection Algorithm for Multivariate Time-series Analysis and its Application in Medical Diagnostic Problems
(2018-08-24)The main purpose of this study is feature engineering/learning from multivariate (MV) time-series to achieve a more interpretable model by dimension reduction. This aim is fulfilled in 2 main parts. In part 1, we proposed ... -
REVEALING HEMODYNAMIC RESPONSE AND DYNAMIC CHANGES IN FUNCTIONAL CORTICAL NETWORKS USING FUNCTIONAL NEAR-INFRARED SPECTROSCOPY (fNIRS)
(2017-12-15)Therapeutic interventions, such as physical therapy and non-invasive brain electrical stimulation can enhance the physical performance of persons with brain disorders. One often-used form of physical therapy named ... -
Whole-head functional brain imaging of economic risk decision making and transcranial photobiomodulation with fNIRS and EEG
(2020-09-08)Functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG) are two non-invasive brain imaging or mapping modalities that allow us to measure cerebral hemodynamic and electrophysiological changes in the ...
