Brain plasticity is important because then it means that the brain can undergo changes that would cause a difference in their behavior or how they sense things, even as an adult. This means that the brain has the lifelong ability to make neural pathways based on new experiences, in other words, the ability to learn. New knowledge and skills are gained through experience or instruction.

The brain is mapped so that it has different regions that are responsible for certain behaviours. In Phantoms of the Brain by V.S Ramachandran, M.D., Ph.D. and Sandra Blakeslee, they provide a diagram of a representation of the body surface on the surface of the brain. The foot comes after the genitals, followed by the trunk, hand, thumb, face, lips, and pharynx. Based on this, various fetishes, or nongential regions of the brain that causes a habitual erotic response, can be explained. For example, a graduate student who had a phantom leg after losing it in an accident said that whenever she had sex, there were strange sensations in her phantom leg. This would be explained by the foot being next to the genitals in the brain. When she still had her foot, it kept the genital region in the brain from taking over, but now that her foot is gone, the genital region encroaches on the foot region, resulting in her feeling her phantom foot whenever she had sexual activity.
