We can locate areas of brain activity by using magnetic resonance imaging. certain areas become active when people have certain thoughts. An example of this can give is the way we can communicate with people in a vegetative state. We can tell a person to think of playing tennis or navigate their house. We can detect their thoughts and interpret them as yes and no becasuse the two different tasks light up different parts of the brain when using an MRI machine. If they think of tennis it would be a yes, or if it is the navigation task we read that as no. I see that as pretty convincing physical evidence for human thought.
Heres an example: http://brainimaging.waisman.wisc.edu/~perlman/papers/Vegetative/Detecting-Awareness-in-the-Vegetative-State.pdf

Brain activity is not always a human though. And you cant just interpret thoughts as yes or no. it doesnt work like that. But normaly, when a person thinks something, his or hers brain is active and that picture only shows the part of brain that is active when a person is thinking something, its not the picutre of an actual thought.

Evidently you can interpret it as 'yes' or 'no' because people do, as I showed. Arbitrarily announcing that it doesn't does not make you right. The brain activity is physical proof that a conscience thought has been made by the user. It may just be the areas of the brain that they are using to complete the task that light up, but it still provides physical evidence of the physical thought in the first place. And the fact that humans can sometimes make a thought with their subconscious does not make any difference to an argument concerning the measurement of a conscience thought.
