Not necessarily, there are plenty of rigorously documented cases of people being conscious without any brain activity.

This article is also pretty interesting: https://www.frontiersin.org/articles/10.3389/fpsyg.2022.9555...

Without brain activity, all that can be demonstrated is the recollection of being conscious. It is well known that we can recall lots of things that never happened, with our brains filling in the blanks with invented details.

I am not aware of rigorously documented cases of people being conscious without any brain activity. Can you point me to some?

See linked article, under "Phenomenon #6: Cognitive abilities can be retained when the brain is seriously compromised", terminal lucidity, etc: "the patients demonstrated normal cognitive abilities just prior to death, contrary to what objective medical findings would have predicted (e.g., EEG, neuroimaging). These patients are operating in an anomalous manner that brings into question the idea that the body is a “puppet” controlled from the inside (the brain) and that perhaps it can function alternately in some instances."

Are you aware of any documented cases of observing brain activity without using consciousness?
