However, people don't show a general dominance of one or other hemisphere. In 2013 a large study was conducted at the University of Utah
[iv] where they analysed brain scans from over 1,000 individuals while at rest. The team found some lateralisation in regions associated with different tasks- those associated with language in the left hemisphere and with controlling attention in the right. However they found no evidence to support the notion that people are intrinsically left or right sided in how their brains are wired.
