Which of the Following is True Regarding Central Adaptation

Question

Which of the following is true regarding central adaptation?
A) At the conscious level, it further restricts the amount of detail arriving at the cerebral cortex.
B) It usually involves the inhibition of nuclei along a sensory pathway.
C) At the subconscious level, it further enhances the amount of detail arriving at the cerebral cortex.
D) It involves the excitation of nuclei along a motor pathway.
E) It occurs outside the CNS along the sensory pathways.

Accepted Answer

Central adaptation usually involves the inhibition of nuclei along a sensory pathway, which leads to a decrease in the transmission of sensory information to the cerebral cortex. This helps to filter out irrelevant or redundant sensory signals and prevent sensory overload in the brain. At the conscious level, central adaptation may further restrict the amount of detail arriving at the cerebral cortex, while at the subconscious level, it may enhance the amount of detail by selectively amplifying certain sensory inputs. Central adaptation does not involve excitation of nuclei along a motor pathway and occurs within the CNS along sensory pathways.
