The physics of functional magnetic resonance imaging (fMRI)

RB Buxton - Reports on Progress in Physics, 2013 - iopscience.iop.org
Functional magnetic resonance imaging (fMRI) is a methodology for detecting dynamic
patterns of activity in the working human brain. Although the initial discoveries that led to …

The relationship between MEG and fMRI

EL Hall, SE Robson, PG Morris, MJ Brookes - Neuroimage, 2014 - Elsevier
In recent years functional neuroimaging techniques such as fMRI, MEG, EEG and PET have
