CA3 pyramidal neuron number, volume, and density estimations in P14 rat hippocampus following prenatal nicotine exposure and/or maternal separation.

<p>MD or NIC alone did not alter neuron number (A) and volume (B), however when combine NIC+MD neurons were significantly increased by 41.3±8.0%, <i>p<0.01</i> (A), and the reference volume was increased by 26.2±4.7%, <i>p<0.05</i>(B). Neuronal density was not different between groups (C). */<i>#/+ p<0.05; **/##/++ p<0.01.</i>
