Figure 2. Repeated stress increases BLA neuronal length and spine number.

Figure 2

BLA neurons (LAT and BA) were grouped together for initial analysis. A) Repeated restraint increased the dendritic length of BLA neurons in Sholl analysis (left) and total dendritic length (middle). There was a rightward shift in the cumulative frequency of BLA principal neurons when total dendritic length was measured (right). B) Repeated stress increased the number of intersections of BLA principal neurons in Sholl analysis. C) Repeated stress increased the number of spines in BLA principal neurons (Sholl analysis, left), increased total number of spines (middle), and caused a rightward shift in the cumulative frequency of total spines in neurons (right). D) Repeated stress increased spine density of BLA principal neurons, demonstrated in Sholl analysis (left), and average neuronal spine density (right).
