ELI5: Could a human brain retain consciousness without a body, assuming it was still receiving adequate oxygen/blood flow?

So basically, if you could supply the brain with enough nutrients, oxygen, blood, etc., through an artificial delivery system, would the brain still be conscious/sentient? It would obviously be unable to receive any form of external stimuli, but would it still be... alive? Able to think?

Remember I'm five, thanks!

Theoretically, sure, but the mind in there would go insane pretty quick. Sensory deprivation is not good at all long term. You need some way to simulate a body and environment for the brain-in-a-jar, or at minimum give it vision and hearing and control over a computer.
