 Also, the images have very high spatial resolution, therefore it captures fine detail, which helps to provide a clear picture of how brain activity is localised.]]> 2016-10-19 10:12:38 UTC https://padlet.com/r_andradeferreira98/9dgengtrt40f/wish/131729377 https://padlet.com/r_andradeferreira98/9dgengtrt40f/wish/131729773 Expensive compared to other neuroimaging techniques and can only capture a clear image if the person stays perfectly still
+ Also,  fMRI scans only measures blood flow in the brain- & so it cannot explain the activity of individual neurons. Therefore it can be difficult to tell exactly the kind of brain activity that is being represented on the screen.
