Publishing in Nature Communications, the team led by Dr Ben Wilson and Professor Chris Petkov explain how using an imaging technique to explore the brain activity in humans and monkeys has identified the evolutionary origins of cognitive functions in the brain that underpin language and allow us to evaluate orderliness in sequences of sounds.
This new knowledge will help our understanding of how we learn – and lose – language such as in aphasia after a stroke or in dementia.
Scanning the brains of humans and macaque monkeys, the research team has identified the area at the front of the brain which in both humans and monkeys recognises when sequences of sounds occur in a legal order or in an unexpected, illegal order.
