Functional Magnetic Resonance Imaging Methods [PDF]

Neuropsychology Review, 2015
Since its inception in 1992, Functional Magnetic Resonance Imaging (fMRI) has become an indispensible tool for studying cognition in both the healthy and dysfunctional brain. FMRI monitors changes in the oxygenation of brain tissue resulting from altered metabolism consequent to a task-based evoked neural response or from spontaneous fluctuations in ...

Avoid or seek light – a randomized crossover fMRI study investigating opposing treatment strategies for photophobia in migraine

The Journal of Headache and Pain, 2022
Background Photophobia, the aberrantly increased sensitivity to light, is a common symptom in migraine patients and light discomfort is frequently found as a trigger for migraine attacks.

Learning and comparing functional connectomes across subjects [PDF]

, 2013
Functional connectomes capture brain interactions via synchronized fluctuations in the functional magnetic resonance imaging signal. If measured during rest, they map the intrinsic functional architecture of the brain.

Does Physical Activity Influence Semantic Memory Activation in Amnestic Mild Cognitive Impairment? [PDF]

, 2011
The effect of physical activity (PA) on functional brain activation for semantic memory in amnestic mild cognitive impairment (aMCI) was examined using event-related functional magnetic resonance imaging during fame discrimination.

On the reconstruction of magnetic resonance current density images of the human brain: Pitfalls and perspectives

NeuroImage, 2021
Magnetic resonance current density imaging (MRCDI) of the human brain aims to reconstruct the current density distribution caused by transcranial electric stimulation from MR-based measurements of the current-induced magnetic fields.

Probing EEG activity in the targeted cortex after focal transcranial electrical stimulation

Brain Stimulation, 2020
Background: Recording electroencephalography (EEG) from the targeted cortex immediately before and after focal transcranial electrical stimulation (TES) remains a challenge. Methods: We introduce a hybrid stimulation-recording approach where a single EEG
