functional neuroimaging


Also found in: Wikipedia.

neuroimaging, functional

Methods used to detect structural abnormalities in the central nervous system and localized brain neural activity in response to performing specific sensory, motor and cognitive tasks. Two common methods are functional MRI (fMRI) and positron emission tomography (PET). These techniques can be used to detect tumours, strokes, focal cerebral lesions, and to map the cortex in healthy individuals. See magnetic resonance imaging; computed tomography; positron emission tomography.

NEUROMEM will provide mechanistic answers to 3 long-standing questions: 1) What is the link between memory and space, and role of spatial context in re-imagining episodes 2) How are the multiple diverse elements of complex life-like events recollected together 3) How can remembered events be read-out as visuospatial imagery Work will comprise psychological and functional neuroimaging experiments using sophisticated designs including use of virtual reality, and corresponding simulations of how such behaviour can be driven by neuronal activity.

Over the last 20 years, the anatomy of language has been investigated with functional neuroimaging techniques based on perfusion and metabolism (PET, fMRI), whose results supported more traditional analyses of anatomo-clinical correlations in selected groups of brain-damaged patients, and have more recently been complemented by so-called virtual lesion studies (through Transcranial Magnetic Stimulation) and evidence of intraoperative direct electrical stimulation.
For the study, the researchers presented participants with a series of pictures and tastes during functional neuroimaging, and then analyzed participants' ratings of their subjective experiences along with their brain activation patterns.
