why brain is not involved in reflex action?

Asked by pooja pujar | 24th Jul, 2011, 12:00: AM

Expert Answer:

It is because most sensory neurons do not pass directly into the brain but synapse in the spinal cord which allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain receives sensory input while the reflex action occurs.
