Concioussness is the total or the effect of processes that happened in the brain.
Are the processes themselves concioussness? Hardly: a computer computes things, a simple body scanner processes data, and there is a bunch of chemistry going all around nature, and you'd hardly argue that makes them concious.
You could say "conscoussness" is something that leads the object to learn about reality. Then it means conscoussness is something that allows you to interact with reality and store it into memory. But even a phone does that.
Conscioussness is a specific behavior of objects that leads to exhibition of that interaction, then.
So, is concioussness is specific behavour that leads to interaction with reality? Well, an ant has such behaviours. Even microorganisms do. An intecately programmed robot or nanobot does. Most people wouldn't say thay're concious, right? Whether they're just reacting to stimuli or exhibiting a complex behavior.
In the end, we only have very tenious indirect signs of concioussness, but once we slice it: any exclusive attributes it seems to exhibit appear to happen all the time in things which are clearly not concious, or at least not considered as such by us. As of now, consciousness seems like a meme.
