BRAIN SCAN
Scanning the Brain - What Is a Brain Scan, Anyway?
It's an exciting time in the study of the human brain and mind. Nary a week goes by that doesn't see a new discovery in the fields of neuroscience and psychiatry, giving new insight into human mental phenomena and mechanisms.
Much of this advance in knowledge is the result of technological advances in brain imaging. It seems that almost every time one hears about some neurological experiment or advance in human neuroscience, the term "brain scan" appears.
Here are the 6 commonly used techniques:
Near infrared spectroscopy
Magnetoencephalography
Electroencephalography
Positron Emission Tomography
Computed tomography
Functional magnetic resonance imaging
In this image one color is used for each of the six scans, can you figure which is which?
