There are sections of the brain that are specialized for certain tasks, for example auditory or visual processing, but concept-based linkages are very person-independent.
Neuron linkages work a little like a kind of sticky RAM. When a concept is learned, it builds connections between existing data units which are stored somewhat randomly. This is one of the reasons why BCI software is so difficult to nail down. In addition to scanner resolution problems, there must be a kind of baseline adaptation that needs to be performed to find what area corresponds to what data per person.
