Meant for Sleep Research, this is a machine that measures electrical activity while you're asleep.

Uses radiation in X-Rays to map out a patient's brain.
It's known as a structural imaging technique.

(Disclaimer: No involvement of cats)

Uses radiation to measure radioactive glucose in the brain.
It's known as a functional imaging technique.

Functional MRI. It's basically using a magnet to measure the iron in blood as its flowing.
It's known as a functional imaging technique.

A giant tube that uses a magnet to create a model of the brain. Useful for looking at specific structures to see if they look different from normal.
