If your way of thinking and communicating is dominated by the left half of your brain – that is, if the regulatory nerve centers for language and verbal intelligence are located in your left cerebral hemisphere – it is most likely that, in addition to being Right-handed, you use your right ear to answer a phone call when your mobile phone rings . In contrast, people with the dominant right half of the brain typically use their left hand to hold the phone and listen with their left ear when taking a call.
Although this fact may seem anecdotal, establishing a relationship between brain dominance and the preferred side to use the mobile phone is a minimally invasive way to find out where the communication and language centers are in a specific person, according to the authors of the research, researchers from Henry Ford Hospital (USA). Until now, hemispheric anesthesia or Wada test was used for the same purpose, a complex procedure that consists of injecting anesthesia into the carotid artery to sleep in the middle of the brain and thus be able to map its activity.
