The field of pain research has progressed immensely due to the advancement of brain imaging techniques. The initial goal of this research was to expand our understanding of the cerebral mechanisms underlying the perception of pain; more recently the research objectives have shifted toward chronic pain – understanding its origins, developing methods for

Conventional functional magnetic resonance imaging (fMRI) is a blunt tool for studying the nervous system because it measures neural activity only indirectly, by way of hemodynamics and neurovascular coupling. Several alternative, nonhemodynamic functional imaging methods are now being explored.

Simultaneous EEG and fMRI Recordings (EEG-fMRI)
2013Scalp EEG is characterised by a limited spatial resolution and by a low sensitivity to generators distant from the cortical surface. In contrast, fMRI is characterised by a good spatial resolution and it is sensitive to signal of deep brain structures. By combining EEG with fMRI, it is possible to detect blood oxygenation level-dependent (BOLD) signal ...

The combination of electroencephalography (EEG) with functional magnetic resonance imaging (fMRI) forms a powerful tool for the investigation of brain function, but concurrent implementation of EEG and fMRI poses many technical challenges. Here, the motivation for combining EEG and fMRI is explored and methods underlying the combination are described ...

fMRI of the Sensorimotor System
2016The extensive application of fMRI to the assessment of the human sensorimotor system has disclosed a complexity that is largely beyond our original understanding. From the available data, it is accepted that this system consists of a large, and somewhat yet unknown, number of cortical and subcortical areas, with a precise location and a specialized ...

Human neuroimaging with functional Magnetic Resonance Imaging has been a key feature of the current wave of psychedelic research, in both healthy and clinical populations. The available data has suggested that classic psychedelics (psilocybin, LSD, DMT) have a characteristic effect of acutely and profoundly disrupting the normal pattern of resting ...

Objective detection of deception was extensively studied, starting from polygraph to more modern techniques, the functional MR (fMRI), and they are based on neural (sympathetic) activation that is evoked in stressful conditions, such as lying. The role of fMRI in neurophysiology has been extensively developed and studied, and its principles lie in the ...
