How much of consciousness is reliant on sensory input?
If you were to remove a person's brain from their body, and adequately supply it with everything it needs to continue functioning, such as oxygen, nutrients, and hormones, what is consciousness like for that person?
Is there anything left to be considered conscious? If so, is it just an existence of thought? What does that even mean?
You are by definition not conscious if you are not perceiving anything.

What would keep you from perceiving your own thoughts? What would keep you from thinking?
If you're right, would having *less* sensory input make you less conscious? For instance, was Helen Keller less conscious than another person who was blind only?

I think you are just misusing the word "concious". You are not conscious when you are deep asleep.

Perhaps I am; let's boil it down further.
Take away a person's senses one at a time, until they have none left.
Would there still be inner experience?

You can perceive your own thoughts though.

Have you ever heard of a sensory deprivation tank?
I think a more interesting question would be "how would a mind develope without ever getting sensory input" like from birth till death, it's only the mind.

Almost certainly not at all.

- thoughts
- pain (headaches)
- feelings (consfusion etc)
I think most people here are conflating the mind and consciousness.
Consciousness is pure awareness, while the mind is the manifestion of consciousness at a particular moment. The mind is influenced by sensory input and emotions, and is one's thoughts and knowledge. The mind cannot exist without consciousness, but consciousness is not reliant on the mind. It can exist on its own, say if a person feels and is thinking nothing or meditating.
To answer OP's question, yes. Both the mind and consciousness can exist in the brain without the senses, but would simply be deprived of new input.
