Then, if they stimulate the brain in a certain way, they can control what people think and create experiences. Therefore, if a person had never seen, heard of, tasted or smelled a cookie, a neurologist should be able to create exactly that experience through brain manipulation. Additionally, there should be no additional mental response when the subject eats their "first" cookie. However, this seems completely false. Neuroscience has progressed and shown that rudimentary manipulation of the brain is possible, but it is counterintuitive to believe that F-fiber firing can suddenly result in entirely new tactile and emotional knowledge. It is more plausible to consider that people describe sensations as what it means to experience something of which they are already aware. So when they receive the real product, they will likely have an emotional response or attachment to it that cannot be explained by their identity.
