Self inquiry - am I my brain?

I have been doing self inquiry lately. I start by removing who I think I am step by step.

Am I my hands? No because if I lose them, this doesn't change my "I"

Am I my eyes? No. When I close my eyes I am still I.

Am I my feelings. No. Because my "I" continues as is in presence of different emotions.

But am I my brain? This I really can't answer. If I lose a small part of my brain, my definition of "I" may change. My understanding of me.

I want to ask you guys what is the answer here. Are we our brains? If we lose our brains, does our "I" remain intact?

What is the answer?
