Question

After Terry lost a finger in an industrial accident, the area of his sensory cortex devoted to receiving input from that finger gradually became very responsive to sensory input from his adjacent fingers. This best illustrates

A. phrenology.
B. neurogenesis.
C. plasticity.
D. tomography.

Answer 1

C.) Plasticity

Step-by-step explanation:

The correct answer is option c.

Plasticity allows the brain to rewire itself or modify its neural connections. This allows the brain to recover from any injury or neural damage. Due to plasticity, Terry's brain adapted to repeated use of the adjacent finger, and his brain became responsive to it. His brain was able to form new neural connections which allowed his hand to function normally as he did before the accident.

Incorrect options-

a. Phrenologists examine or read the skull's protrusion as a way to understand human personality and character.

b. In neurogenesis, new neurons are produced in the brain. This is an important process when the embryo is developing and this continues in certain regions of the brain throughout the lifespan.

d. Computerized tomography is a procedure involving diagnostic imaging which includes X-rays and computer technology which can produce pictures of the inside of the body.
