Assessing Local and Branch-specific Activity in Dendrites

•Dendrites nonlinearly integrate inputs to increase neural complexity.•Branch-specific dendritic activity shapes selectivity, plasticity, and behavior.•Biophysics, spatiotemporal patterning, and inhibition structure dendritic activity.•Blind patch clamp electrophysiology facilitates intracellular dendritic access.•In vivo two-photon calcium imaging enables population dendritic imaging.
