This test measures the functioning of the trigeminal nerve, the nerve that TCE seems to affect most directly. Feldman found that the blink reflex of every family member, of both children and adults, was either slower than normal or fell barely within the normal range. Feldman was impressed not so much by the degree of individual impairment but by the uniformity of the group. He told Schlichtmann that the results were “highly significant,” that the odds of a group of twenty or more people all testing out at the slow end of normal were “a million to one.”
