Intelligence 'networks’ discovered in brain for the first time

Scientists from Imperial College London have identified for the first time two clusters of genes linked to human intelligence. Called M1 and M3, these so-called gene networks appear to influence cognitive function - which includes memory, attention, processing speed and reasoning. Crucially, the scientists have discovered that these two networks - which each contain hundreds of genes - are likely to be under the control of master regulator switches. The researchers are now keen to identify these switches and explore whether it might be feasible to manipulate them. The research is at a very early stage, but the scientists would ultimately like to investigate whether it is possible to use this knowledge of gene networks to boost cognitive function. Traits such intelligence are governed by large groups of genes working together - like a football team made up of players in different positions Dr Michael Johnson, lead author of the study from the Department of Medicine at Imperial College London, said: "We know that genetics plays a role in intelligence but until now haven't known which genes are relevant. This research highlights some of genes involved in human intelligence, and how they interact with each other.
