Why does Posit Science have more than one suite for brain fitness?

The brain is probably the most complex piece of machinery in the world. It has many diverse systems with unique exercise needs. To achieve widespread brain fitness, you must work out different areas of the brain. Part of the reason that Posit Science has a 40-person Scientific Advisory Board is that they each bring their specialized expertise to the team. Some advise us on the auditory system, some the visual system, some on the attention system, and so on.
