Functional magnetic resonance imaging (fMRI) is a non-invasive technique that is widely
available and can be used to determine the spatial relationships between tumor tissue and …

BACKGROUND: A craniotomy with direct cortical/subcortical stimulation either awake or
under general anesthesia (GA) present 2 approaches for removing eloquent region tumors …

OBJECTIVE: To illustrate how lesion-induced neurovascular uncoupling at functional
magnetic resonance imaging (fMRI) can mimic hemispheric dominance opposite the side of …

A left-handed patient with a grade II left frontal lobe astrocytoma had spontaneous seizures
causing speech arrest and uncontrolled right upper extremity movements. Word-generation …

The coupling mechanism between neuronal firing and cerebrovascular dilatation can be
significantly compromised in cerebral diseases, making it difficult to identify eloquent cortical …

Background Perirolandic motor area gliomas present invasive eloquent region tumors within
the precentral gyrus that are difficult to resect without causing neurologic deficits. Study Aims …

To examine the functional connectivity of the primary and supplementary motor areas (SMA)
in glioma patients using resting-state functional MRI (rfMRI). To correlate rfMRI data with …

Object Early and aggressive resection of low-grade gliomas (LGGs) leads to increased
overall patient survival, decreased malignant progression, and better seizure control. This …

Neurovascular uncoupling that causes fMRI data to underestimate viable neuronal activity in
the brain is detected and indicated to assist in pre-surgical planning. Tasks associated with …

Functional magnetic resonance imaging (fMRI) is a powerful, non-invasive technique for
mapping human brain function. Because of the robust signal intensity changes associated …
