Fmri weakness
WebfMRI weakness. complex, noisy, expensive, poor temporal. MRI strength. no radiation, soft tissue contrast, shows great detail. MRI weakness. expensive, noisy, claustrophobic, no … WebfMRI weakness 1. Poor temporal resolution because there is 5 second time lag from the time the neurons Fire to the image on the screen being produced. 2. Cannot establish cause and effect. 3. Difficult to tell what brain activity is shown on the screen because only blood flow is shown not the activity of individual neurons. 4.
