How do you explain perfect pitch? No imprinting there but an individual can tell a perfect scale; what mechanism exists in the brain that allows for that? I mean how are you born knowing the musical scale? I ask as a general question of interest. The brain as computor thing; the last artcle on brain chemistry I read resulted ina perplexed group of neuro-scientists who could not understand how information could be processed in one part of the brain when the neural connections were severed with anothewr part of the brain; yet the information was available in a part of the brain that had no connectivity. They tried calling it Neural intuition as part of a neural net. But they remain perplexed. As do I. The pattern recognition is a theory that resolved from brain studies and was applied to the study of programmming algorythims; But that doesn't make the brain a computor; it makes certain aspects of thought to resemble computation. To say the brain is a computor is like saying the ruler is the distance. Or the backhoe is the building. No dispute here; just speculation.
