Deciphering genetic relationships in cognitive function takes serious effort. Michael Posner at the University of Oregon in Eugene and colleagues found that a diminished ability to focus could be linked to two specific mutations.[1]
The study involved a battery of genetic and cognitive tests given to more than 200 people. A year later, in 2003, Posner added clarity to the finding using functional magnetic resonance imaging (fMRI). The researchers linked the mutations to differing activity in the anterior cingulate cortex.[2]
This study required only 16 subjects.
