These arguments may be of some use to you:
The mind is immaterial, but the brain is material. Mental processes are immaterial, but all the fundamental particles except photon, graviton, and gluon are material. The photon and graviton are not stationary but always travel at light speed, and the gluon activities are confined within the atomic nucleus, so it is impossible for them to be identical to mental processes. Therefore, the mind cannot be identical to the brain, and mental processes cannot be identical to any of the fundamental particles. The mental and the physical are essentially separate and fundamentally different.
But that is only part of the whole story. The brain – the functioning brain to be exact – is not exclusively material but is composed of non-material parts or the functional parts, such as the signal-processing part and the metabolic part, too. But only the signal-processing part contains information and has information-processing capability identical to the mind. (If you examine the mind carefully, you’ll find that it just contains information and processes information. It does nothing else.)
Therefore, it is logical to conclude that the mind is the signal-processing part of the brain. That is the mind is just “the functional part” of the brain. This is why, although it is not identical to the brain, it is totally dependent on the brain. You may call this dualism in the sense that there are not one but two parts of this universe: the physical material part and the functional non-material part.
I can’t give you the names of philosophers who back this idea, but you can read more detailed discussion here. But I hope, in this forum, it is the logic of the idea, not the name of a philosopher, that counts.
