Explain brain plasticity, and give an advantage and a disadvantage of this process.
What will be an ideal response?
Brain plasticity is the reorganization of synapses according to how much different parts of the brain are used. An advantage is that people who lose a sensation, such as vision, may develop greater sensation in another area, such as the fingertips of a blind person who uses Braille to read. A disadvantage is that the process is imperfect, and sensations may persist from a body part that is no longer there, such as phantom pain from an amputated limb.
