Texting alters brain rhythm



Washington: Texting can change your brain waves, according to a new study that found a unique ‘texting rhythm’ in people who used their smartphone to text message, reports PTI. People communicate increasingly via text messaging, though little is known on the neurological effects of smartphone use, researchers said. To find out more about how our brains work during textual communication using smartphones, researchers analysed data from 129 patients.

Their brain waves were monitored over a period of 16 months through electroencephalograms (EEGs) combined with video footage. Researchers from the Mayo Clinic in the US found a unique ‘texting rhythm’ in about one in five people who were using their smartphone to text message while having their brain waves monitored.

The researchers asked patients to perform activities such as message texting, finger tapping and audio cellular telephone use in addition to tests of attention and cognitive function. Only text messaging produced the newly observed brain rhythm, which was different than any previously described brain rhythm.

The unicity of the texting rhythm compared to other forms of mental stimulation could be caused by the combination of mental activity with motor and auditory-verbal neurological activity. No correlation was found between the presence of a texting rhythm and the patients’ demographic information, including age, gender, epilepsy type, presence of a brain lesion on MRI, or ictal EEG.

“We believe this new rhythm is an objective metric of the brain’s ability to process non-verbal information during use of electronic devices and that it is heavily connected to a widely distributed network augmented by attention or emotion,” said William Tatum, director of the epilepsy monitoring unit and epilepsy centre at Mayo Clinic, who led the study.

Next to smartphones, the texting rhythm was also found in iPad users. The researchers hypothesised that the presence of a different brain wave rhythm while using mobile, handheld devices might be caused by their smaller screens, which require more concentration.
