Modern technology allows us to map brain activity to specific areas of the brain. MRI (Magnetic Resonance Imaging) and FMRI (Functional Magnetic Resonance Imaging) have allowed scientists to study the structure and activity of the brain in detail.

MRI scans work by creating a magnetic field around the thing being scanned and induces different chemical elements to emit radio waves This will give a 2D cross section of the internal structures of the brain which can then be built up into a 3D one.

FMRI works in more or less the same way as MRI except that it is also able to track blood flow. This allows us to see which areas of the brain are active when certain prescribed activities are performed and is therefore especially useful in the study of brain function.
