## Core Concept
The question pertains to the effects of decortication on reflexes in animals. Decortication refers to the removal or functional loss of the cerebral cortex, which is the outer layer of the brain responsible for processing sensory information, controlling movement, and facilitating thought, perception, and memory. The cerebral cortex plays a significant role in the regulation and integration of various physiological and psychological functions.

## Why the Correct Answer is Right
In decorticate animals, the righting reflex is significantly impaired or lost. The righting reflex, also known as the labyrinthine righting reflex, is crucial for maintaining the body's posture and orientation in space. This reflex involves the integration of sensory inputs from the labyrinth of the inner ear, the eyes, and proprioceptors in the muscles to make the necessary adjustments to keep the body upright. The cerebral cortex, particularly the motor and sensory areas, plays a role in coordinating and fine-tuning these reflexes. Without the cortex, the animal's ability to right itself or maintain a normal posture is compromised.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because the specifics of option A are not provided, but generally, other reflexes might not be directly impacted by decortication in the same way the righting reflex is.
- **Option B:** Similarly, without specifics, it's noted that other reflexes might not be lost due to decortication.
- **Option D:** This option is incorrect for the same reason as options A and B; the details are not provided, but typically, decortication affects specific higher-order functions and reflexes like the righting reflex.

## Clinical Pearl / High-Yield Fact
A key point to remember is that decorticate animals exhibit a range of neurological deficits, including loss of the righting reflex, indicating the critical role of the cerebral cortex in integrating sensory information and motor responses. This has implications for understanding neurological disorders and injuries that affect the cerebral cortex in humans.

## Correct Answer: B. righting reflex.
