Cell Phone Use May Indicate Brain Dominance [Study]

Cell phone use could indicate brain dominance.

The side of your head you hold your cell phone to could reveal which half of your brain you use the most, according to a study by lead researcher Michael Seidman, of the Department of Head and Neck Surgery at Henry Ford. Chances are, if you hold your cell phone to your left ear, the right side of your brain dominates your mind. However, this may not be entirely true, as you may hold it to your left ear and write with your right hand.

Dr. Seidman stated:

“by establishing a correlation between [brain] dominance and sidedness of cell phone use, it may be possible to develop a less-invasive, lower-cost option to establish the side of the brain where speech and language occurs rather than the Wada test, a procedure that injects an anesthetic into the carotid artery to put part of the brain to sleep in order to map activity.”

In other words, it may be possible to put half of your brain to sleep in order to discover how easily you function socially in the meantime, but using a cell phone might make the procedure unnecessary. Cell phone use could be a major determining factor toward figuring out which side regulates your speech and communication.

The study also reveals that cancer in your head, neck and brain may not have any connection to how you hold your phone at all. In other words, you might get a tumor in the side of your brain opposite where you listen to your cell phone.

You might take this as a clue that using Bluetooth to talk on the phone, preferably when you’re not behind the wheel of a motor vehicle, is just inconsiderate. Bluetooth makes you harder to understand, and just planting that phone next to your ear won’t harm you at all and makes you sound much clearer (hint, hint).

The study for brain dominance was based on online surveys sent to 5,000 people with questions about what side of the head you most commonly put your cell phone against, history of tumors, and hand dominance. Again, the study still remains a theory, as some of us hold the device to our left ear and write with the opposite hand, and we’re not ambidextrous.

Do you think there is any connection between cell phone use and brain dominance?
