BCI Brain Signal Targets: Part IV

I have argued in parts I, II, III that the brain signal is a direct reflection of the mind. I have also claimed a better definition of the latter would yield better brain signal “targets” for designer, tester, and user of a BCI device. I now wish to explain further how these targets might help the user.

First, state of mind targets could be defined by the user, with conscious intent. This gives the user more control over the whole process. She can decide what she wants to do with her mind, during device operation, with a full and clear awareness. What states of mind might she wish to strive toward, and express, during her daily life? Or for that matter, during her time in the lab. She can research, discuss and arrive at a personalized, ideal target states of mind. These targets may take into account her lifestyle, occupation, social habits, and personal goals. She could define her most desired, realistic and easily-to-attain states of mind.

These personalized or user-defined states of mind would be the targets for her to try to “hit.” For example, if she meditates regularly, “mindfulness during BCI movement” might be one target.

The user could do their own research in designing her targets. For example, the user might learn it’s difficult to maintain a constant level of excitement/dopamine brain signal, when one is both failing and succeeding at artificial movement. Social situations would magnify this effect. In this case, the user could define a state of mind that allows for emotional flexibility and variability.

On the other hand, the user might be a devoted Buddhist who is (or strives to be) unattached to results. In this case, she could define her target as “an even level of excitement while moving.”

Overall, personalized mind/brain targets could be researched, considered, and defined by the user — in conjunction with her clinical and professional team, as well as family and friends. The user could construct fairly rigid/consistent, or more flexible targets — according to the demands of the situation, the physical environment, etc. These targets would be hit more strongly, consistently and precisely since (1) the targets more accurately reflect her state of mind, (2) she has a clear idea of what the targets are, and (3) she is motivated to hit them.
