AO3

• fMRI scans are not invasive and would not cause the participants any discomfort, leading to more accurate recordings.
• Risk free, no ethical issues so more likely to be used but patients find it uncomfortable.
• fMRI may overlook the interconnectivity of brain sites. By only focusing on brain sites receiving increased blood flow, it fails to account for the importance of brain sites connecting/communicating with each other.
• Takes up to 5 seconds to create the image after the brain activity has occurred, so can't record spontaneous behaviour.
• Cannot zone in on activity of specific neurons = difficult to interpret.
• fMRI can safely provide a clear picture of how brain activity is localised.
• fMRI is expensive compared to other techniques. It has poor temporal resolution because of the 5-second lag between initial neural activity and image, meaning fMRI may not truy represent moment to moment brain activity.
