Understanding neurovascular coupling is of paramount importance since while a normal coupling is vital for a healthy functioning brain, the impairment in coupling is the underlying factor of many neurodegenerative diseases. ...

This study is focused on investigating the cerebrovascular dynamics of migraine by analyzing data acquired from healthy and migraine subjects with a noninvasive measuring technique, fNIRS during a breath holding task. Brain ...

Mental disorders are usually associated with functional abnormalities of brain that are revealed by behavioral symptoms. Attention-deficit hyperactivity disorder (ADHD), in particular, is well known to be a common behavioral ...

Although breath-hold diving is nowadays practiced as a competitive sports dis- cipline, its underlying physiological mechanisms enabling divers to tolerate great dive depths and durations are still not fully understood. E ...

Longstanding diabetes mellitus is associated with gastrointestinal symptoms and disturbances of gastrointestinal motility. Diabetic patients with a history of mic rovascular and macrovascular complications such as ...

A strong relationship between mechanical and physiological conditions of skele- tal muscle determines the force generated by that muscle. The aim of this study was to evaluate the relationship between local oxygen consumption ...

In the last decade, functional near-infrared spectroscopy (fNIRS) has been introduced as a new neuroimaging modality with which to conduct functional brain studies that require data collection from vision center or motor ...

Investigating the relationship between the hemodynamic changes and cognitive activity (known as the neurovascular coupling) provides a basis of the underlying physiology of the brain energy mechanisms. The aim of this study ...

In this thesis, the steady state human visual evoked potentials that are generated in response to visual stimulation and its corresponding hemodynamic response are investigated via electroencephalography (EEG) and functional ...

Multimodal investigation of blood oxygenation level-dependent (BOLD) signal, using both functional near infrared spectroscopy (fNIRS) and functional magnetic resonance imaging (fMRI), may give further insight to the ...
