Aristotle: heart was the source of feeling, brain simply cool the blood from the body.

Electrical: implant electrodes, send small currents to stimulate the brain and observe what happens. Magnetic: expose a part of the brain to a magnetic field ex. Optogenetics: genetically engineer brain to respond to a certain light frequency, shoot the light on the targeted brain part and see what happens: eeg. Place electrodes on the skull, it will pick up electro activity of the brain. Accuracy up to a single neuron: neuroimaging techniques. Exposed to powerful magnetic field, the tissue will start to emit electromagnetic radiation. Pick up the radiation and transfer it into the structure of the brain. Injected with radioactive molecule (glucose), the computer follow the activity of the molecule.
