highly significantp<0.01
There was a highly significant difference in the laminar distribution in number of cells (χ 2 = 15.6, df = 4, p<0.01) but the direction of this difference varied with lamina; when collapsed into supragranular, granular and infra-granular laminae, there was no significant difference between the two groups, (χ 2 = 3.65, df = 2, p>0.1).
