Specifically fMRI measures blood flow across the brain (the BOLD response) which is correlated with neuron activity. It has good spatial resolution but poor temporal resolution [0], compared to EEG which gives you good temporal resolution but poor spatial resolution.

[0] i.e. you know with precision where in the brain activity occurred, but less precisely when it occurred in time
