Sending text messages on a smartphone or iPad can change the rhythm of brain waves in humans -- a finding that has significant implications for brain-computer interfacing gaming and driving. People communicate increasingly via text messaging though little is known on the neurological effects of smartphone use. To find out more about how our brains work during textual communication using smartphones a team led by Mayo Clinic researcher William Tatum analysed data from 129 patients. Their brain waves were monitored over a period of 16 months through electroencephalograms (EEGs) combined with video footage. Dr Tatum found a unique 'texting rhythm'
