Correct. Many reflexes do not involve the CNS at all. Some, like the
patellar reflex mentioned, take place entirely at the level of the spine.
The brain find out about it *after* it happens. That reflex, BTW, is the
same one that makes you recover quickly when you step into a hole. It
makes walking possible.
Some reactions are mediated in lower brain, and require no concious input,
but still go through CNS. Some require concious monitoring and decision

Some can, with practice.
