I feel that Marr would also think it is time to look again at the levels of understanding framework—now emphasizing the connections between levels and their synergies.” — Tomaso Poggio, Afterward to the 2010 reprint of David Marr’s Vision
The fascinating detail in the hierarchical connectivity of the brain, particularly the visual system, is that the numerically dominant synaptic connectivity comes not from the sensory periphery but from many other brain areas. As Marcus Raichle describes it, this connectivity and intrinsic activity can be thought of as the “dark matter” of the brain {Raichle, 2006, #85; Raichle, 2010, #612}. Blah
