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 ...

Independent component analysis is becoming a popular exploratory method for analysing data from FMRI experiments. Its application, however, has been somewhat restricted by the lack of ability to quantify statistical significance. We present an integrated approach to probabilistic ICA for FMRI data that allows for nonsquare mixing in the presence of ...

Blood oxygenation level dependent functional magnetic resonance imaging (BOLD fMRI) is widely used by the neuroimaging community for studies of the brain, but remains controversial in the spinal cord despite demonstrations of technical feasibility. As yet the majority of motor studies have focussed on hand movement or finger tapping, while painful and ...

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 ...

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 ...

fMRI of the Sensorimotor System
2015This chapter focuses on a key characteristic of the somatosensory as well as the motor system, that is, its somatotopic organization. The good spatial resolution of functional MRI (fMRI) as compared to previous functional neuroimaging approaches such as positron emission tomography has allowed noninvasive studies at hitherto unknown spatio-anatomical ...
