fMRI & TV
"Watching too much television can change the structure of a child's brain in a damaging way, according to a new study. Researchers found that the more time a child spent viewing TV, the more profound the brain alterations appeared to be. The Japanese study looked at 276 children aged between five and 18, who watched between zero and four hours TV per day, with the average being about two hours. MRI brain scans showed children who spent the most hours in front of the box had greater amounts of grey matter in regions around the frontopolar cortex - the area at the front of the frontal lobe. But this increased volume was a negative thing as it was linked with lower verbal intelligence, said the authors, from Tohoku University in the city of Sendai. They suggested grey matter could be compared to body weight and said these brain areas need to be pruned during childhood in order to operate efficiently. ‘These areas show developmental cortical thinning during development, and children with superior IQs show the most vigorous cortical thinning in this area,’ the team wrote." - Daily Mail (Jan 2014) and Washington Post (Dec 2013) and Cerebral Cortex (Nov 2013)
"Scientists are just beginning to use brain imaging to understand how humans process thought during real-life experiences. For example, researchers have compared scans of adults watching an entertaining movie to see if neural responses are similar across different individuals." -

"To what extent do all brains work alike during natural conditions? We explored this question by letting five subjects freely view half an hour of a popular movie while undergoing functional brain imaging." - ScienceMag.org (March 2004)
