To identify which of lucy's brain areas was most active when she talked, neuroscientists gave her a temporarily radioactive form of glucose and a "PET scan".
A positron emission tomography (PET) scan is an imaging test that enables your specialist to check for sicknesses in your body. The output utilizes an exceptional color containing radioactive tracers. These tracers are either gulped, breathed in, or infused into a vein in your arm contingent upon what part of the body is being examined.
