Somewhat unsurprisingly, medical technobabble is more tough.
I swear most of Beta is brain parts...
I could get you a copy of the ICD9 codes....that's every diagnostic code for everything you could have wrong with you....
Maybe look at these as trees, instead. Brain is the organ, the sub parts being temporal, parietal, frontal, etc.
There's likely a standard list of things I can do to any of those brain sub-parts.
