Contributions of functional Magnetic Resonance Imaging (fMRI) to the study of numerical cognition [PDF]

open access: yesJournal of Numerical Cognition, 2018
Using neuroimaging as a lens through which to understand numerical and mathematical cognition has provided both a different and complementary level of analysis to the broader behavioural literature. In particular, functional magnetic resonance imaging (fMRI) has contributed to our understanding of numerical and mathematical processing by testing and ...

The Processing of First- and Second-Order Motion in Human Visual Cortex Assessed by Functional Magnetic Resonance Imaging (fMRI)

open access: yesJournal of Neuroscience, 1998
We have examined the activity levels produced in various areas of the human occipital cortex in response to various motion stimuli using functional magnetic resonance imaging (fMRI) methods. In addition to standard luminance-defined (first-order) motion,

The variation of functional connectivity and activity before and after thalamotomy surgery (review)

open access: yesFrontiers in Human Neuroscience, 2023
Ablation surgeries are utilized to treat certain brain disorders. Recently, these surgeries have become more prevalent using techniques such as magnetic resonance guided focused ultrasound (MRgFUS) ablation and Gamma knife thalamotomy (GKT).

Physiological basis and image processing in functional magnetic resonance imaging: Neuronal and motor activity in brain

open access: yesBioMedical Engineering OnLine, 2004
Functional magnetic resonance imaging (fMRI) is recently developing as imaging modality used for mapping hemodynamics of neuronal and motor event related tissue blood oxygen level dependence (BOLD) in terms of brain activation.

Imaging Somatosensory Cortex: Human Functional Magnetic Resonance Imaging (fMRI)

open access: yes, 2022
Functional magnetic resonance imaging (fMRI) is a powerful tool for imaging somatosensory cortex, providing a means to non-invasively measure cortical activity in awake and behaving humans. Notably, this technique has permitted the homunculus – a hallmark of primary somatosensory cortex (S1) organization – to be examined with unprecedented detail. With

Current methods and limitations for longitudinal fMRI analysis across development

open access: yesDevelopmental Cognitive Neuroscience, 2018
The human brain is remarkably plastic. The brain changes dramatically across development, with ongoing functional development continuing well into the third decade of life and substantial changes occurring again in older age.

Personalized Network‐Guided Neuromodulation Enhances Human Working Memory

open access: yesAdvanced Science, EarlyView.
A personalized neuromodulation framework combining individualized functional brain network targeting with real‐time neural decoding is introduced. Using concurrent TMS–fMRI, participant‐specific stimulation targets and optimal frequencies are identified. Only optimal‐frequency stimulation improves working memory across sessions.
