The brain doesn’t have a direct role to play in reflex actions.

Explanation:
Reflex actions are rapid and automatic responses to stimuli that help protect the body from harm. Brain doesn’t play an important role instead spinal cord is crucial to reflex actions.

When a stimulus is detected by sensory receptors, the sensory information travels through sensory neurons to the spinal cord. In the spinal cord, the information is processed and a reflex response is generated through a reflex arc, which involves a sensory neuron, an interneuron, and a motor neuron.
