When Discriminating Among Different Textures, the Amount of Neuronal Firing

When discriminating among different textures, the amount of neuronal firing by sensory receptor neurons is proportional to the

A) novelty of the texture object.
B) natural nature of the texture (e.g., dirt vs. an artificial texture, e.g., metal) .
C) size of the textured object.
D) shape of the textured object.
E) roughness of the texture object.
