Positron emission tomography (PET)
... from the cerebral cortex, but can only detect changes over large areas of the brain and very little sub-cortical activity. Functional magnetic resonance
imaging (fMRI) measures changes in blood flow in the brain, but the activity of neurons is not directly measured, nor can it be distinguished ...
... Data Bank (PDB)
Main article: Protein Data Bank
The structure of proteins can be determined crystallographically or by nuclear magnetic resonance
. Protein structures solved by these methods are commonly deposited in the freely accessible Protein Data Bank. Nearly 25,000 protein structures ...
