If thinking, language, memory, action and perception are all made thanks to common circuitry (prefrontal cortex), what issues does it raises about these 5 so old research thematics?
I might be wrong, but I view the prefrontal cortex much more as a coordinator/supervisor of the other functions than as the responsible of them. For instance (and simplifying a lot!): the memory storage could still be in the temporal lobes (I am oversimplifying), but the prefrontal cortex could contribute to memory when need to extract something from the storage, in other words, when you need to remember a world. PFC might be the responsible of the strategy to remember. Thus, PFC contributes to memory BUT it is a memory area only, as this same reasoning applies to all the other functions.
I concur with the notion of a coordinating matrix that sorts, retrieves and holds certain stimuli, however, from the perspective of clinical work, another central function may be to 'ignore' certain stimuli and inputs in order to bring others into central focus
