BACKGROUND Resting state (task independent) Functional Magnetic Resonance Imaging (fMRI) has opened a new avenue in cognitive studies and has found practical clinical applications. MATERIALS AND METHODS Resting fMRI analysis was performed in six patients with brain tumor in the motor cortex. For comparison, task-related mapping of the motor cortex was(More)
Human memory is an enigmatic component of cognition which many researchers have attempted to comprehend. Accumulating studies on functional connectivity see brain as a complex dynamic unit with positively and negatively correlated networks in perfect coherence during a task. We aimed to examine coherence of network connectivity during visual memory encoding(More)
Measuring neuro-haemodynamic correlates in the brain of epilepsy patients using EEG-fMRI has opened new avenues in clinical neuroscience, as these are two complementary methods for understanding brain function. In this study, we investigated three patients with drug-resistant reflex epilepsy using EEG-fMRI. Different types of reflex epilepsy such as eating,(More)
Understanding the pathophysiology of reflex epilepsy using simultaneous EEG-fMRI. Using motor imagery to study the neural substrates of dynamic balance. Evidence that the negative BOLD response is neuronal in origin: a simultaneous EEG-BOLD-CBF study in humans. Increased sensitivity of fast BOLD fMRI with a subject-specific hemodynamic response function and(More)
BACKGROUND Emotion entails cognitive processes that may either be conscious or unconscious. Emotions influence all aspects of cognition. AIM The aim of the following study was to study the effect of education on neural correlates of emotions in healthy normal volunteers. MATERIALS AND METHODS Sample consisted total of 61 healthy young educated adults in(More)
