fMRI doesn’t measure neural activity itself, however: it detects changes in oxygenated blood flows in response to cognitive tasks, correlating to neural activity (Lee et al., 2017). 2015-09-28 Resting state fMRI (rsfMRI or R-fMRI) is a method of functional magnetic resonance imaging (fMRI) that is used in brain mapping to evaluate regional interactions that occur in a resting or task-negative state, when an explicit task is not being performed. A number of resting-state conditions are identified in the brain, one of which is the default mode network. 2019-08-21 fMRI, on the other hand, has incredibly good spatial resolution but suffers from poor temporal resolution. fMRI, unlike EEG, is not an electric response measured from a pyramidal cell. Instead, it a haemodynamic response that reflects changes in blood oxygenation as neurons engage in a process called the blood oxygen level dependent (BOLD) signal. Hannah Devlin explains how fMRI is used and answers some common criticisms of fMRI.
