Brain Image (IMAGE) Imperial College London Caption This image shows the Default Mode Network (red/yellow) and the Salience Network (blue/green) which have important roles in social and emotional function. These two networks in the brain were altered when the volunteers received the hormone kisspeptin, and this was associated with changes in brain activity linked to sexual aversion and sexual arousal.
