Imaging Neuroscience is aiming to reveal functional changes, that is, changes in brain activity, and structural changes, which address changes in neuroanatomy. There is a growing interest in defining functional interactions of different brain regions based on the increased sensitivity and specificity of functional magnetic resonance imaging (fMRI). The present contribution is a brief overview o...

Aging studies consistently show a relationship between decreased gray matter volume and decreased performance on working memory tasks. Few aging studies have investigated white matter changes in relation to functional brain changes during working memory tasks. Twenty-five younger and 25 older adults underwent anatomical magnetic resonance imaging (MRI) scans to measure gray matter volume, diffu...

Functional Magnetic Resonance Imaging(fMRI) is a noninvasive imaging technique that measures the hemodynamic response related to neural activity in the human brain. Event-related functional magnetic resonance imaging (efMRI) is a form of functional Magnetic Resonance Imaging (fMRI) in which a series of fMRI images are time-locked to a stimulus presentation and averaged together over many trials...

calcifying aponeurotic fibroma (caf) is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet, in children and adolescents. due to its infiltrative nature, this tumor can mimic malignancy on preoperative magnetic resonance imaging (mri) and has a predilection for local recurrence. there are very few reports in the literature that describe featur...

Since it was introduced a decade ago, functional magnetic resonance imaging (fMRI) has come to dominate research on the human brain. However, fMRI maps are based on secondary metabolic and hemodynamic events that follow neuronal activity, and not on the electrical activity itself. Therefore, the representation provided by fMRI cannot be assumed a priori to be exact. The accuracy of these maps d...

Functional magnetic resonance imaging (fMRI) is a relatively new and noninvasive method of functional brain mapping. Functional MRI is increasingly being applied to the study of neuropsychiatric disorders, including schizophrenia, Alzheimer's disease, traumatic brain injury, and others. Particularly noteworthy are findings related to plasticity in the adult human brain. Despite the promise of f...

Studies using functional magnetic resonance imaging (fMRI) to map cortical areas in humans have revealed many similarities with recent cortical mapping studies from nonhuman primates as well as some striking differences. Improved methods for analyzing, displaying and averaging fMRI data on an unfolded cortical surface atlas are poised to improve the integration of information across burgeoning ...
