Recent research that was conducted seems to be contentious with the notion that memory is useful for sustaining a higher level of brain functions.
At the University of Wisconsin in Madison, researchers have found that brains tend to store unimportant information far away from the reaches of average, everyday brain functions. But they were subsequently able to recall that information using magnets applied to the brain.
This research that was conducted seems like it might be beneficial for people who struggle with diseases like schizophrenia and depression. A professor at this opportunity, Brad Postle, agrees with this assessment.
He believes that mental illness comes hand in hand with what the mind thinks about. But this research leads him to believe that they will be able to have complete and utter control over what the mind thinks about.
Postle also believes that people might be able to focus on more than what the memory is actually capable of containing. He compared it to vision, with many things being visible, but with only a few things actually existing in focus.
The conscious mind actually generates the idea that the mind is aware of all things at any given moment with the feeling that all of the things you think about are being stored in your mind all at once. But the research conducted seems to indicate you are only conscious of a very small number of things at any one moment.
