Brain chooses which ear to use for cell phone calls

If you primarily think with your left-brain, then there is a very good chance that you make use of your right hand in order to hold your cell phone close to your right ear, a new study conducted by the Henry Ford Hospital in Detroit is claiming.

The new study has found a very strong link between brain dominance and the ear that is used to listen to a cell phone call, with over 70 percent of those who were involved in the study holding their cell phone to their ear on the exact same side as their dominant hand. Those people who have their speech and language centers located on the left side of their brain are much more likely to make use of their right hand for the purposes of writing and other day-to-day activities.

The Henry Ford Hospital study also shows that the great majority of left-brain dominant people also use their cell phone in their right ear even though there is no discernible difference in hearing between either their left or right ears. Likewise, right brain dominant people are much more likely to make use of their left hand in order to hold the cell phone to their left ear.

“Our finding has several implications, especially for mapping the language center of the brain,” says Michael Feidman MD, FACS.
