Morphological changes in CA1 neurons

Morphological features	Low LG	High LG
Dendritic length (basal) (μm)	331.49 ± 23.11	463.25 ± 37.28**
Dendritic length (apical) (μm)	1216.79 ± 140.23	1570.91 ± 73.46*
Spine number per 20 μm (basal)	10.93 ± 0.72	13.85 ± 0.85*
Spine number per 20 μm (apical)	11.71 ± 0.86	16.33 ± 1.42*
Number of branching point (basal)	3.22 ± 0.71	3.98 ± 0.42
Number of branching point (apical)	12.6 ± 1.46	16.02 ± 1.02

Morphological features of CA1 dendritic trees are summarized. Note that dendritic length was significantly shorter for both basal and apical dendrites in low versus high LG offspring (*p < 0.05; **p < 0.01). Spine density was also found to be significantly lower in basal as well as apical dendrites in low compared with high LG offspring (*p < 0.05; **p < 0.01).
