A) was significantly different between species.
B) closely matched the lowest amplitude that activated Meissner corpuscles.
C) closely matched the highest amplitude that activated Meissner corpuscles.
D) closely matched the lowest amplitude that activated Pacinian corpuscles.
E) closely matched the highest amplitude that activated Pacinian corpuscles.
