Functional magnetic resonance imaging (fMRI) relies upon blood oxygenation level dependent (BOLD) signal changes for mapping brain activation in humans and animals. The shape of the BOLD fMRI signal can vary considerably even across structures of the sa...

We report findings from a study of visual word processing, in which data from both functional Magnetic Resonance Imaging (fMRI) and Magnetoencephalography (MEG) were analyzed by correlating single trial activations with continuous stimulus variables. 16...

“Delay discounting” refers to a phenomenon in which individuals prefer immediate gains to future gains of comparable or greater value. Prior functional magnetic resonance imaging (FMRI) studies have documented greater mesolimbic activation when people c...

Recent functional magnetic resonance imaging (fMRI) studies showed stronger activation of multisensory brain areas during cross-modal binding perception compared to unisensory perception of the same events. This study aimed at reproducing this finding a...

Human cognitive experiments have been largely done using functional Magnetic Resonance Imaging (fMRI) to record hemodynamic responses in the dorsolateral prefrontal cortex correlated to target based tasks (D'Esposito, Ballard et al. 2000; Pochon, Levy e...

Blood Oxygen Level Dependent (BOLD) functional magnetic resonance imaging (fMRI) is used to infer levels of neural activity by examining signal changes associated with changes in deoxyhemoglobin (Hbr) concentration. The most commonly used mapping signal...

Neurovascular coupling is the central principle of functional magnetic resonance imaging (fMRI), and thus critical for the interpretation of most fMRI data. While the strong majority of studies support a tight coupling between neuronal and vascular acti...

One in four patients born with the 22q11.2 deletion develops schizophrenia, making this heterozygous deletion the most significant genetic risk factor for the disorder. Both functional magnetic resonance imaging (fMRI) studies in humans and in vivo tetr...

Our eyes are constantly in motion and the various kinds of eye movements are closely linked to many aspects of human cognitive processing. Measuring all possible eye movements unobtrusively is not achievable with current methods. Video-based eye-trackers only measure rotational but not translational motion of the eye, require a calibration process relying on the participant’s self-report of accurate fixation, and do not work if vision of the eyeball is blocked. Scleral search coils attach physical weight on the eyeball and also do not measure translation. Here, we describe a novel and fully automated method to use real-time magnetic resonance imaging (MRI) for eye tracking. We achieved a temporal resolution sufficient to measure eye rotations and translations as short as those that occur within a blink and behind a closed eyelid. To demonstrate this method, we measured the full extent of the blink-related eye movement for two individuals, suggesting that the eye approaches a holding position during lid clo...

Background/motivation: Neurological disorders are common in patients with coronavirus disease 2019 (COVID-19), but their underlying mechanisms are poorly understood. While hospitals worldwide are acquiring clinical MRI data in patients with COVID-19, th...
