Spine density in the outer molecular layer is not altered in granule cells with hilar basal dendrites.

<p>(A) 2D-projected confocal image stacks of individual dendritic segments of dentate granule cells imaged in the outer molecular layer. Scale bar: 2 µm. (B) Spine density analysis of granule cells with and without hBDs (n = 13 segments from no-hBD and 10 segments from hBD-GCs; in 10 cultures). Spine densities were not significantly different.
