Unformatted text preview: Suppose you had recordings for all neurons, would you know how we perceive things? Would we even know how the nonlinear voltages in this neuron arose? David Marrs three levels of understanding computations. Another level of complexity arises from circuits! This circuits function depend on nonlinear synaptic mechanisms. Different oscillations arise in this circuit, although individual neurons are simple. Summary ! To understand the brain, one must formulate computational theories and understand neural constraints. ! Marr expanded this notion to three levels of understanding, including representation as an intermediate step. ! Another level of complexity arises by interactions in neural networks....
