Fractional composition of CA1, CA2, CA3 and DG in P14 rat hippocampi after prenatal nicotine and/or maternal deprivation.

<p>The data for each hippocampal subregion is presented as a percentage of total neurons or neuronal volume of the hippocampus. The table summarizes data presented in pie graphs. Direction of arrows denotes relative increase (↑) or decrease (↓) in fractional composition of neuron number or volume compared to control animals. ↑ or ↓, p<0.05; ↑↑ or ↓↓, p<0.01; ↑↑↑ or ↓↓↓, p<0.001.
