Question

If a person lacks one sense organ the brain concentrates on remaining sense organs and these sense organs become more sensitive.
A. True
B. False

Answer 1

Hint: The blind and deaf have quite enhanced abilities and a heightened sixth sense as well. This enables them to fight against any kind of danger.

Complete answer: Research in the field of neurobiology has proven to some extent, that in cases where any of the sense organs are poorly developed or even non-functional, the brain readily adapts to compensate for the loss by developing the other sensory organs. It is widely believed that this happens as they are forced to depend on their other sensory organs more and eventually skills develop over a period of time with continuous learning. Blind people have immensely sensitive ears and they can hear more clearly than most of the people with normal eyesight.
They follow the auditory cues and learn to adapt to those efficiently.

Therefore, the correct answer is option A. True.

Note: These relatively new research results are inclusive of the ongoing research on neuroplasticity (the ability of our brains to change with experience). The brains of the deaf and blind have been extensively studied to trace clues regarding the limits of the plasticity of the brain and its underlying mechanisms.
If one sense is lost, the areas of the brain normally devoted to handling that sensory information do not go unused they get rewired and put to work processing other senses.
