Multitasking is seem as a major asset among individuals but a new study reveals that simultaneous use of different media devices, such as phones and laptops, could lead to alteration in the brain structure.
According to the study by University of Sussex, people who frequently use several media devices at the same time have lower grey-matter density in one particular region of the brain compared to those who use just one device occasionally.

The study found that independent of individual personality traits, people who used a higher number of media devices concurrently also had smaller grey matter density in the part of the brain known as the anterior cingulate cortex (ACC), the region notably responsible for cognitive and emotional control functions.
Researcher Kep kee Loh said that media multitasking is becoming more prevalent in our lives today and there is increasing concern about its impacts on our cognition and social-emotional well-being. Our study was the first to reveal links between media multitasking and brain structure.
The study was published in Plos One.
