Figure 7. Apical dendrite morphology of Pyramidal Cells within the Central (CeA) and Medial (MeA) Amygdala.

Aged animals averaged significantly longer apical dendrites (a) and greater number of branch points (c) than Adult animals in the CeA. There were no significant differences in apical dendrite length in the MeA (b). Adult Female Control animals had a significantly greater number of branch points than Adult Female EtOH animals (d, indicated by line and star). No significant differences in total number of spines or spine density along apical dendrites in either the CeA (e,f) or MeA (f,h).
