State the role of brain in reflex action?

Reflex actions are sudden responses that do not involve thinking. It is an involuntary action. For example, when we prick ourselves with thorns, we withdraw our hand immediately without thinking. 

Reflex arcs are formed in the spinal cord, although the information inputs also reach the brain. 

The role of the brain in a reflex action is shown below-

The sensory area of the brain receives the information, interprets it, and makes a rapid decision based on past experiences -> The message is transmitted to the motor area -> motor neurons sends the information to the receptor organ which is controlled by the medulla in the hindbrain.
