Final answer:
The firing rate of a cell depending on the number of fingers touched provides information about the shape of the object being held.
Step-by-step explanation:
When the firing rate of a cell depends on the number of fingers that are touched, it gives us information about the shape of the object being held. Different shapes can lead to different patterns of firing in the cells of our skin. For example, if a person is holding a round object, the firing rate of the cell will be different compared to when they are holding a square object.
