How Watching Tv Affects Brain Neuroplasticity?
How does watching tv affect our brain? We know that it can be both good and bad for us, but recent research is showing that it might have more of a negative impact than we thought.
One study found that just one hour of television per day can lead to brain changes in children. These changes included decreased gray matter in the frontal lobe, which is responsible for language, executive function, and social cognition.
In another study, researchers looked at how tv affects the brains of older adults. They found that those who watched more than three hours of television per day had a more difficult time processing information and were more likely to have lower brain volume.
So what does all this mean? It seems that tv viewing, especially in excess, can lead to decreased brain function and even shrinkage. So if you want to keep your brain healthy and plastic, it might be best to limit your screen time.
A new study has found that watching television can cause changes in the brain that resemble those seen in people with Alzheimer’s disease.
The research, which was carried out by scientists at the University of Gothenburg in Sweden, looked at a group of healthy adults aged between 18 and 30 years old.
The participants were asked to fill in a questionnaire about their TV viewing habits, including how many hours they watched per week and what type of programs they usually watched.
MRI scans were then used to assess the participants’ brain structure and function.
The findings, which are published in the journal PLOS ONE, showed that those who watched more than four hours of TV per day had lower levels of gray matter in the medial temporal lobe – an area of the brain that is known to be affected in Alzheimer’s disease.
The TV viewers also had poorer scores on tests of working memory and attention span than those who didn’t watch TV.
“Our results show that Watching too much television may be harmful,” said lead author Ingmar Skoog. “It is possible that the effect is attributable to a reduction in neuroplasticity.”
