UW Madison has an excellent fMRI (functional MRI) being used in brain research.
AEP stands for Auditory Evoked Potentials. When the brain is stimulated by an artificial source, they are trying to Evoke the brain to respond. This response is measured in electrical Potentials, these are the wave forms of an EEG. They can stimulate the brain with Visual stimuli (VEP) and Auditory stimuli (AEP).
I know of an excellent chiropractor near Madison. He used to practice here in Idaho. Check out William F Schneider, DC in either Oregon or Watertown, WI. If he used to practice in Boise, Idaho, he is the one I liked. Tell 'Dr Bill' Mark from Idaho say Hi.
Regarding a good mTBI lawyer, check out
www.tbilaw.com. A expert TBI lawyer will be able to arrange a fee sharing arrangement. If your attorney is problematic with a fee share, he runs the risk of mal-practice for not providing expert legal representation.
How long has it been since you could work? You may be ready to apply for Social Security Disability Insurance benefits. You can apply as a year of disability is approaching. Sounds like you are going to need it. In fact, if your average wages for all of last year are less than $1000 per month, you already qualify from an income basis..
My best to you.
