Stereology Parameters from unilateral cerebral cortex neuron and volume estimation of control and fetal alcohol-exposed (FAE) monkeys (ΣQ− total number of neurons sampled; ΣF number of disectors sampled; V cortical gray volume; N total number of neurons CE (ΣQ−) coefficient of error for ΣQ; CE (ΣF) coefficient of error of ΣF; and CE (N) coefficient of error for N). Values are given as mean (CV = SD/mean).
