<p>(<b>A</b>) Average spontaneous firing rates of OT (left) and PCX units (right). Each point represents average within units of 2 sec prior to odor, across 4–6 trials (<i>n</i> = 30 OT units, 25 PCX units). Horizontal bars = average ± SEM. *<i>p</i><0.05, 2-tailed <i>t</i>-test. (<b>B</b>) Average spontaneous firing rates of males and female units within the OT (left) and PCX units (right). Same data as in (A). Horizontal bars = firing rate average across units ± SEM. n.s. = <i>p</i>>0.05, 2-tailed <i>t</i>-test.</p
