Probing brain function by vibrating the fingertips
One of our favorite quotes of the year is from someone who was considering purchase of a Brain Gauge for his practice. But then he consulted a lawyer, and the lawyer told him “you can’t prove that the Brain Gauge does anything other than test finger function.”
In the court of law, this is probably true. People have had enormous difficulty proving that anything means anything in that arena (including EEGs, MRIs, MEGs, etc.) and the Brain Gauge would be no exception.
