Thomas Schweizer, director of the neuroscience research program at St. Michael’s Hospital, conducted brain-imaging scans for a study on how talking hands free on a cell affects driving. He and his colleagues observed that there are many collisions involving left handed turns.  So, they asked seven women and nine men between the ages of 20 and 30 to drive simulators while their brains were scanned with portable MRIs. The drivers had to engage in several types of skills such as driving straight or make left and right turns with and  without traffic. At  the same time, while on the phone, they had to answer simple questions such as “does a triangle have four sides?”  Unfortunately, if on the phone – even if hands free –  the brain areas needed to conduct the physical driving move were turned off to contend with the phone conversations. One of the conclusions is that the people must think about what they are doing when doing more complex driving activities. See the journal Frontiers in Human Neuroscience for this article.
