This chapter uses the view of multilevel mechanistic explanation developed in the preceding chapters to construct a model of the mosaic unity of neuroscience. To develop the mosaic model, a historical example of progress toward the unity of neuroscience is considered: the LM research program. It is argued that the mosaic model of the unity of neuroscience is better suited than reduction to the descriptive, explanatory, and epistemic projects for which these classic models were designed.
