Nicotine-induced dendritic remodeling in the insular cortex

► Nicotine remodels basilar dendrites in the insular cortex. ► Nicotine increases total length and number of bifurcations of basilar dendrites. ► Dendrite remodeling occurs between 40 and 140 μm from the soma. ► Dendrite remodeling is specific to basilar, and not apical, dendrites in the insular cortex.
