Quantitative analysis of reelin-positive immunostained Cajal–Retzius cells in tangential sections of 0.21 mm² from layer 1 of the somatosensory cortex of wildtype and 5-HT_3A receptor KO mice.

Analysis was performed on reelin layer 1 P4 and P14 tangential sections of three wildtype and four knockout mice. CV, coefficient of variation.
