Scientists discovered that our brain exhibits dual and separate functionality or 'split brain' when we do two concurrent, unrelated tasks such as browsing Facebook while watching TV.
A fascinating new study by neuroscientists Shuntaro Sasai of University of Wisconsin-Madison and his colleagues, hypothesized that a brain may functionally split into two separate systems when two unrelated tasks without common functional streams were performed.
They focused their study on Functional split brain in driving/listening paradigm
, which is also the name of the said study.
The researchers gathered thirteen participants and scanned their brain using fMRI. These participants performed virtual driving tasks while navigating the road system. The participants were then asked to perform a a different task which employs concurrency.
I hypothesize that this is a zero functioning split brain. LOL.
To test how the brain performs the 'split', one task concurrent to driving must be related in functionality with driving itself, which is listening to a GPS voice to navigate the road while driving. The other one must be unrelated in functionality which is listening to the radio while driving.
The scientists found that even there were two tasks but when the tasks correlated in functionality were performed, the brain showed a high degree of functional connectivity. This means that parts of the brain that share the same functional properties is highly functioning in this 'integrated task'.
On the other hand, the split brain occurred in the other two concurrent but unrelated tasks. The two networks of the brain are found to be working independently or 'split task'.
Furthermore, it is found that the integrated information, which is tied to the concept of consciousness is high in the integrated task and zero in the split task.
This study lifts the notion that in certain situation in our daily life, our single brain may have been functioning into two separate functional network similar to what is observed in patients with an anatomical split.
Spongebob does not have a brain. Fact.
For a fast-paced environment that we are in, it is likely that we have greatly developed our abilities to high function as a 'split brain'.
