Invertebrate and vertebrate examples illustrate the mechanisms used in constructing nervous systems. Focus on the cellular and molecular mechanisms that underlie questions about the basis of neuronal diversity, axonal pathfinding and target recognition, synaptogenesis, and activity-dependent plasticity. Course overlaps with: NEUSCI 302. Prerequisite: minimum grade of 2.0 in either BIOL 350 or BIOL 355. Offered: Sp.
