AP PSYCHOLOGY

Detailed explanation-1: -fMRI scans have a spatial resolution of approximately 1-2 mm which is significantly greater than the other techniques. EEG, on the other hand, can only detect the activity in superficial regions of the brain.

Detailed explanation-2: -Strengths and weaknesses of fMRI From the discussion above, a primary strength of fMRI is its relatively high spatial resolution and availability.

Detailed explanation-3: -Spatial Resolution: EEG has a spatial resolution of centimeters and limited below cortical surface. MEG has a spatial resolution of millimeters at cortex and is less precise for deep sources. fMRi has a spatial resolution of millimeters and is not limited to cortical areas.

Detailed explanation-4: -Thus, fMRI is considered to have the best spatial resolution among the functional neuroimaging techniques. The operating costs of fMRI are more reasonable than the nuclear imaging techniques (PET and SPECT).

Detailed explanation-5: -The spatial resolution and temporal resolution of fMRI surpasses that of PET, and it is widely known that there is also no radiation exposure [Table 1]. In fact, for a single scan, PET has a better signal-to-noise ratio (SNR) than fMRI.
