Neonatal Tactile Stimulation Downregulates Dendritic Spines in Layer V Pyramidal Neurons of the WAG/Rij Rat Somatosensory Cortex

<div>(a) Median number of spine subtypes in layer V pyramidal neurons of control Wistar, control WAG/Rij, maternally separated WAG/Rij, and tactile-stimulated WAG/Rij rats. (b) Photomicrographic (2000x) representation of different dendritic densities and dendritic spine types in four groups. The magnifications show examples of each dendritic spine type. (c) In the bottom, a schematic representation of each dendritic spine type is presented and matched with related arrows. Scale bar 5 <i>μ</i>m (b).</div>
