Here’s a new word to add to your brain-function vocabulary. Magnetoencephalography or MEG is a type of brain scanning that can allow “researchers to observe neural activity with frequency waves that are faster than 50 cycles per second. An article by Elizabeth Armstrong Moore, published in CNET, explains that the human brain is so fast that it cannot be fully observed using the current gold standard: functional magnetic resonance imaging (fMRI). According to senior researchers and neurology professor Maurizio Corbetta, "Brain activity occurs in waves that repeat as slowly as once every 10 seconds or as rapidly as once every 50 milliseconds.”Enter this new brain scan equipment: magnetoencephalography or MEG. It can not only detect neural activity at the millisecond level but also sample neural activity every 50 milliseconds
