Which statement reflects Ayres's theory of central nervous system (CNS) organization?
A) Critical aspects of sensory integration are seated in the higher levels of the CNS (i.e., cortex).
B) The brain stem assumes a directive role and inhibits lower levels of the CNS.
C) Increased efficiency at the levels of the brain stem and thalamus enhances higher-order functioning.
D) The higher levels of the CNS (cortex) replace lower-level functions (e.g., brainstem and thalamus).

Ayres's theory of CNS organization suggests that increased efficiency at the lower levels of the CNS (such as the brain stem and thalamus) can enhance higher-order functioning. This is because these lower levels are responsible for basic sensory and motor processing, and more efficient processing here frees up resources for more complex processing at higher levels (such as the cortex). This view is often used to explain the benefits of sensory integration therapy, which aims to improve the efficiency of sensory processing at these lower levels.
