Reflexes are automatic, involuntary responses or impulses. Most reflexes do not involve the brain, however, more complex reflexes have to involve the brain in order to process the reflexes. An example of this would be blinking the eye. This is a complex reflex and it must involve the brain. Also, you must take in the place the reason why reflexes do not involve the brain: because it could cause serious damage to the body. Complex reflexes will not cause serious damage if it uses to brain to produce the impulse.
