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. aphasia
c. hemispherectomy
d. plasticity
e. tomography

Answer 1

The reorganization of the sensory cortex in response to the loss of Terry's finger demonstrates neuroplasticity, highlighting the brain's capacity to adapt by changing its neural connections. The correct option is d.

Step-by-step explanation:

The sensory cortex reorganization that occurs in Terry's case, wherein the area that used to receive input from his amputated finger has become responsive to sensory input from his adjacent fingers, is an example of neuroplasticity.

This phenomenon is a clear illustration of how the brain's neural connections can reorganize themselves to adjust to new situations, such as the loss of a limb.

It is evident that the human sensory system is highly adaptable, and the somatosensory cortex, which maps the sensory inputs from different parts of the body, can change its structure in response to injury or damage.

This adaptability is part of what allows for the recovery and continued functionality of the sensory system.The correct option is d.
