Language-cognition brain activity. Coloured posit- ron emission tomography (PET) scans of the areas of the brain active while understanding language. The fronts of these human brains are at left. Active parts of the cerebral left hemispheres are red/orange. Various language areas of the extra sylvian temporal region are active in the scan at left,which shows activity associated with working out the meaning of words. The other scan shows activity associated with understanding sentences. The scans involved injecting radioactive oxygen-15 into the bloodstream to allow areas of the brain with high metabolic activity to be seen | |
