Brain scans for configurable art

I've been struggling with what is within my reach financially and technologically to use new brain scan technology to begin to test and build configurable art. Brain scans for configurable art.  That's the idea.

But, it's not that simple, I think a direct measure of aesthetic preference needs to be built from underlying components of desire.  At this stage, neuroscience is struggling and debating how to actually measure preference.  Neural activity in some part of the brain means -- what?

Functional- MRI's are more expensive and measure blood-flow deep in the brain, and can pinpoint actual location of the brain's response to any activity you can do while lying in a little tube with a massive magnet spinning around you. EEG's are external measures of electrical output, and capture brain waves, namely alpha, beta, theta, .....indicators of attention and relaxation.  EEG's are old, low-tech and now shockingly cheap, single sensors are in toys (yes, Mattel has a toy) but, it's not clear that they can actually measure much.

I'm hunting for any slim possibility to find relative ways to measure individual response to sensory stimulus.  Found an article about using EEG's to measure Emotion.  It was 'thin', but gave me a glimmer of hope.

Stay tuned, I'm working on the sensory stimulus....I think it's connected to taste-buds, tactile response, auditory preference....namely other senses.  It's possible all your sensory inputs are related and somehow build your unique, complex equation of aesthetic preference.  Look at my post and related article on neural fluency, your preferences probably all relate to how easily your brain processes them.  Stay tuned.
