Modern psychiatric declamations about schizophrenia can be lot nonsense, propelled by the desire to show that they know something about a gadgetry about which they actually know nothing. Secondly there is the issue of eking a livelihood, with mastery over a dubious science.
Trying to find the real machine that runs and maintains the human brain without having a minimal understanding of the world of software is quite idiotic. It is time that mental science professional took a look at how software do run machines. From this point they can return back to conceptualizing on how the brain works.
Mental triggers can be connected to signals, both tangible as well as non-tangible. Tangible part can be even such things as words as well as codes in languages. Non-tangible inputs can be signals that can be slightly akin to Mobile signals or wireless networking.
The way that modern mental science professionals are seeking to understand the working of the human brain is like a Watch-mechanic tinkering with a mobile phone or a computer hard disk to repair them with a mechanical means. He or she should have the knowledge that there is a non-see-able entity called software that runs them. There is no way he can approach it with mechanical means. In many ways, this world of software is another phase of reality; not connected to matter.
