This chapter summarizes experiments and theory that are relevant to the role of dendrites in plasticity. Since the vast majority of synapses form connections onto the dendritic arbor of a neuron, synaptic plasticity is fundamentally a dendritic phenomenon. Dendrites integrate incoming information to elicit local dendritic spikes that help trigger plasticity mechanisms. However, synapses far from the soma may be relatively more isolated from axonally initiated action potentials, which are important—although not always required—for long-term synaptic plasticity. As the excitability of dendritic arbors is itself plastic, synaptic plasticity must be coordinated with dendritic plasticity for the control of neuronal computations and neural circuit functions.

Keywords:   dendrite, action potentials, synaptic plasticity, dendritic arbors, neural circuit, neuronal computation
