As a former nurse student, who has had vocational training on a neurosurgical ward, I can safely say that yes, the mind is in fact the brain. People with e.g. hydrocephalus had almost always a change in mental activity as soon as they got the shunt they needed. People with head trauma were not the same when they left our ward after a week of care. Thus, when the brain matter is under stress, the psyche changes. It's as simple as that.
When I was young, there was a god with infinite power protecting me. Is there anyone else who felt that way? And was sure about it? but the first time I fell in love, I was thrown down - or maybe I broke free - and I bade farewell to God and became human. Now I don't have God's protection, and I walk on the ground without wings, but I don't regret this hardship. I want to live as a person. -Arina Tanemura
