Excerpt
Much has been revealed about the human brain in the past few
decades. In vivo visualization of the human brain is more accessible
to psychiatrists and other clinicians with the emergence of high-resolution
magnetic resonance imaging (MRI). Functional neuroimaging research
has rapidly expanded, first with positron emission tomography (PET)
and single-photon emission computed tomography (SPECT), and more
recently with functional MRI (fMRI), a technique that offers improved
resolution and wider access.
