WebMagnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body. Most MRI … WebAny FMRI experiment is only as good as its hypothesis, design and interpretation. Silly FMRI experiments, for instance one showing men’s amygdala’s (which play a key role in generating emotion) light up when viewing Ferraris, are not difficult to find. But such work doesn’t prove any fatal flaw in FMRI, merely poor use of a good tool.

The goal of fMRI data analysis is to detect correlations between brain activation and a task the subject performs during the scan. It also aims to discover correlations with the specific cognitive states, such as memory and recognition, induced in the subject. The BOLD signature of activation is relatively weak, however, so other sources of noise in the acquired data must be carefully con… WebAbout Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ...
