Cortical Activation Through Passive-Motion Functional MRI.
BACKGROUND AND PURPOSE Functional brain mapping is an important technique for neurosurgical planning, particularly for patients with tumors or epilepsy; however, mapping has traditionally involved invasive techniques. Existing noninvasive techniques require patient compliance and may not be suitable for young children. We performed a retrospective review of our experience with passive-motion fu...
متن کاملVisualizing cortical activation during mental calculation with functional MRI.
Cortical activation during arithmetic calculation (silent subtraction by sevens) was compared to that observed during a control condition for which subjects were required to count forward by ones. Nine normal subjects underwent 1.5-T functional magnetic resonance imaging while performing these tasks. All subjects showed bilateral premotor, posterior parietal, and prefrontal cortex activation du...
متن کاملSomatosensory cortical activation identified by functional MRI in preterm and term infants
Functional MRI (fMRI) has not previously been used systematically to investigate brain function in preterm infants. We here describe statistically robust and reproducible fMRI results in this challenging subject group using a programmable somatosensory stimulus synchronized with MR image acquisition which induced well-localized positive blood oxygen level dependent (BOLD) responses contralatera...
متن کاملCortical activation during swallowing rehabilitation maneuvers: a functional MRI study of healthy controls.
OBJECTIVE/HYPOTHESIS We hypothesize that the central response during swallowing rehabilitation is critical and may be exploited to maximize the therapeutic benefit. We seek to provide preliminary data regarding the neural networks associated with commonly employed rehabilitation strategies to increase our understanding of the neural bases underlying these maneuvers. STUDY DESIGN Case series. ...
متن کاملEffect of acute hyperglycemia on visual cortical activation as measured by functional MRI.
To determine whether acute hyperglycemia changes the hyperemic response to functional activation of brain, the area and magnitude of the activation were measured in healthy volunteers maintained at euglycemia and then at hyperglycemia using the hyperglycemic clamp technique. Activation of the visual cortex (8-16 Hz) was assessed by functional MRI with blood oxygenation level dependent (BOLD) co...
