Fig. 2.

Effect of chronic stress and lithium treatment on CA3 pyramidal cell dendritic length and branch points in each experimental group. White bars, control chow (n = 7); light gray bars, lithium control (n = 7); black bars, stress (n = 9); and hatched bars, stress with lithium (n = 7). Chronic stress significantly reduced the length of apical (A), but not basal (B), dendrites. Chronic stress significantly reduced the number of branch points on the apical dendrites (C), and it had marginal effects on basal dendrites (D). CLT prevented the stress-induced decrease in apical dendritic length but did not have significant effects on its own or prevent stress effects on the number of branch points.
