Document Summary
A method for creating a representation (not image) of brain activity while the brain"s owner is perfoming some task. Often, the representation includes one or more images, but these images are. The two are related, but they are different. Images are not actual pictures of brain in action. They are elaborate reconstructions that depends on complex mathematical assumptions and methods of analysis. This limitation remains true no matter how compelling and beautiful the images may be. Claims are often more persuasive if they are accompanied by neuroimage. What properties would be ideal? (with functional neuroimaging) Temporal resolution (measure events in brain to a few milliseconds, because neuro functions play out on a small time-scale) Low-noise (sensitive, if you had a thermometer that read within 10 degrees ferenheit, that"s not good); Reliability (samel reading, whatever it is, same results every time)
