Genes responsible for bigger brains are found: Discovery could be the key to tackling dementia
A group of genes can help build a bigger brain.
While this has long been known, a number of new links between genes and brain size have now been found by British scientists.
The discovery opens up a new avenue of research to better understand brain development and diseases like dementia, researchers claim.
A team of scientists from the Universities of Bath and Lincoln compared the genomes of 28 mammals with differing sizes of neocortex.
This is the region of the brain that is involved in language and decision-making.
The size of this region differs hugely between species, and is the part... read more
