You clearly know little about psychological research techniques if you don't know how they test rats for memory. Ever heard of the term "rat in a maze"?
I meant complex memory, not simply pathing repetition that can be replicated with an EEPROM and a few lines of code.
And by that, I mean, how people are using activity in areas of the brain to say that a person is 'x' or what thinking about 'y'. It's phrenology for a new age.
Define "complex memory". Do you mean episodic memory?
fMRI only shows correlation, not causation; any neuroscientist knows this. To prove a causative relationship, you need to use other methods (lesions or TCMS, for example). Show me an example of what you're talking about.
And, what do you mean by "farce of fMRIs"?
