That seems like some serious B.S., like political debate type B.S.
Do you or don't you believe that a physical process in the brain is exactly and completely the experience of pain? Saying yes means that pain is a process of the elementary particles and not anything else.
WTF else might it be?
We know there isn't anything else that can interact with the physical world on relevant scales. If it is able to interact via electromagnetism, gravity, or even one of the intranuclear forces, then it's physical. If it isn't able to interact by one of those mechanisms, then it can't interact at all. Pain can be caused by physical trauma; so that rules out the second possibility; ergo, pain can only be a process of the elementary particles of the standard model. Or quantum mechanics is completely wrong.
We can rule out pain being due to ANYTHING not in this diagram, because we KNOW that we are made of electrons, quarks and photons; and that there is nothing not in this diagram that can interact with any of those things, and that exists at energies a human could survive.
We can also most likely rule out anything in the second or third columns; so pain can only possibly be the interaction of some combination of the two quarks and two leptons in the first column, and the five bosons on the right hand side of this diagram.
It is highly unlikely that neutrinos, or any bosons other than the photon, are necessary for the process we call 'pain'; so it can in principle be boiled down to the interactions of just four fundamental particles - albeit in huge numbers and interacting in a monumentally complex fashion.
As can almost everything else in human experience.
There is no room for woo. The god of the gaps is dead, and he took mind-body dualism with him.
Knowing all about bricks doesn't mean you know all about every possible structure you could ever build from bricks - not by a long shot - but it does mean that you can be sure that there are no undiscovered kinds of brick, and no interactions with bricks that you don't know about.
